Tokyo Tech’s TSUBAME3.0 Will Be First HPE-SGI Super

Thu, 02/16/2017 - 22:37

In a press event Friday afternoon local time in Japan, Tokyo Institute of Technology (Tokyo Tech) announced its plans for the TSUBAME 3.0 supercomputer, which will be Japan’s “fastest AI supercomputer,” when it comes online this summer (2017). Projections are that it will deliver 12.2 double-precision petaflops and 64.3 half-precision (peak specs).

Nvidia was the first vendor to publicly share the news in the US. We know that Nvidia will be supplying Pascal P100 GPUs, but the big surprise here is the system vendor. The Nvidia blog did not specifically mention HPE or SGI but it did include this photo with a caption referencing it as TSUBAME3.0:

That is most certainly an HPE-rebrand of the SGI ICE XA supercomputer, which would make this the first SGI system win since the supercomputer maker was brought into the HPE fold. For fun, here’s a photo of the University of Tokyo’s “supercomputer system B,” an SGI ICE XA/UV hybrid system:

TSUBAME3.0 is on track to deliver more than two times the performance of its predecessor, TSUBAME2.5, which ranks 40th on the latest Top500 list (Nov. 2016) with a LINPACK score of 2.8 petaflops (peak: 5.6 petaflops). When TSUBAME was upgraded from 2.0 to 2.5 in the fall of 2013, the HP Proliant SL390s hardware stayed the same, but the GPU was switched from the NVIDIA (Fermi) Tesla M2050 to the (Kepler) Tesla K20X.

Increasingly, we’re seeing Nvidia refer to half-precision floating point capability as “AI computation.” Half-precision is suitable for many AI training workloads (but by no means all) and it’s usually sufficient for inferencing tasks.

With this rubric in mind, Nvidia says TSUBAME3.0 is expected to deliver more than 47 petaflops of “AI horsepower” and when operated in tandem with TSUBAME2.5, the top speed increases to 64.3 petaflops, which would give it the distinction of being Japan’s highest performing AI supercomputer.

According to a Japanese-issue press release, DDN will be supplying the storage infrastructure for TSUBAME 3.0. The high-end storage vendor is providing a combination of high-speed in-node NVMe SSD and its high-speed Lustre-based EXAScaler parallel file system, consisting of three racks of DDN’s high-end ES14KX appliance with capacity of 15.9 petabytes and a peak performance of 150 GB/sec.

TSUBAME3.0 is expected to be up and running this summer. The Nvidia release notes, “It will used for education and high-technology research at Tokyo Tech, and be accessible to outside researchers in the private sector. It will also serve as an information infrastructure center for leading Japanese universities.”

“NVIDIA’s broad AI ecosystem, including thousands of deep learning and inference applications, will enable Tokyo Tech to begin training TSUBAME3.0 immediately to help us more quickly solve some of the world’s once unsolvable problems,” said Tokyo Tech Professor Satoshi Matsuoka, who has been leading the TSUBAME program since it began.

“Artificial intelligence is rapidly becoming a key application for supercomputing,” said Ian Buck, vice president and general manager of Accelerated Computing at NVIDIA. “NVIDIA’s GPU computing platform merges AI with HPC, accelerating computation so that scientists and researchers can drive life-changing advances in such fields as healthcare, energy and transportation.”

We remind you the story is still breaking, but wanted to share what we know at this point. We’ll add further details as they become available.

Drug Developers Use Google Cloud HPC in the Fight against ALS

Thu, 02/16/2017 - 21:00

Within the haystack of a lethal disease such as ALS (amyotrophic lateral sclerosis / Lou Gehrig’s Disease) there exists, somewhere, the needle that will pierce this therapy-resistant affliction. Finding the needle is a trial-and-error process of monumental proportions for scientists at pharmaceutical companies, medical research centers and academic institutions. As models grow in scale so too does the need for HPC resources to run simulations iteratively, to try-and-fail fast until success is found.

That’s all well and good if there’s ready access to HPC on premises. If not, drug developers, such as ALS researcher Dr. May Khanna, Pharmacology Department assistant professor at the University of Arizona, have turned to HPC resources provided by public cloud services. But using AWS, Azure or Google introduces a host of daunting compute management problems that tax the skills and time availability of most on-site IT staffs.

These tasks include data placement, instance provisioning, job scheduling, configuring software and networks, cluster startup and tear-down, cloud provider setup, cost management and instance health checking. To handle these cloud orchestration functions tied to 5,000 cores of Google Cloud Preemptive VMs (PVMs), Dr. Khanna and her team at Arizona turned to Cycle Computing to run “molecular docking” simulations at scale by Schrödinger Glide molecular modeling drug design software.

The results: simulations that would otherwise take months have been compressed to a few hours, short enough to be run during one of Dr. Khanna’s seminars and the output shared with students.

Dr. May Khanna

Developing new drugs to target a specific disease often starts with the building blocks of the compounds that become the drugs. The process begins with finding small molecules that can target specific proteins that, when combined, can interact in a way that becomes the disease’s starting point. The goal is to find a molecule that breaks the proteins apart. This is done by simulating how the small molecules dock to the specific protein locations. These simulations are computationally intensive, and many molecules need to be simulated to find a few good candidates.

Without powerful compute resources, researchers must artificially constrain their searches, limiting the number of molecules to simulate. And they only check an area of the protein known to be biologically active. Even with these constraints, running simulations takes a long time. Done right, molecular docking is an iterative process that requires simulation, biological verification, and then further refinement. Shortening the iteration time is important to advancing the research.

The objective of Dr. Khanna’s work was to simulate the docking of 1 million compounds to one target protein. After a simulation was complete, the protein was produced in the lab, and compounds were then tested with nuclear magnetic resonance spectroscopy.

“It’s a target (protein) that’s been implicated in ALS,” the energetic Dr. Khanna told EnterpriseTech. “The idea is that the particular protein was very interesting, people who modulated it in different ways found some significant improvement in the ALS models they have with (lab) mice.   The closer we can link biology to what we’re seeing as a target, the better chance of actually getting to a real therapeutic.”

“Modulating,” Dr. Khanna explained, is disrupting two proteins interacting in a way that is associated with ALS, a disease that currently afflicts about 20,000 Americans and for which there is no cure. “We’re trying to disrupt them, to release them to do their normal jobs,” she said.

She said CycleCloud plays a central role in running Schrödinger Glide simulations. Without Google Cloud PVMs, simulations would take too long and model sizes would be too small to generate meaningful results. Without CycleCloud, the management of 5,000 PVM nodes would not be possible.

CycleCloud provides a web-based GUI, a command line interface and APIs to define cloud-based clusters. It auto-scales clusters by instance types, maximum cluster size and costing parameters, deploying systems of of up to 156,000 cores while validating each piece of the infrastructure. Additionally, it syncs in-house data repositories with cloud locations in a policy / job driven fashion, to lower costs.

It should be noted that the use of Google Cloud’s PVMs, while helping to hold down the cost of running simulations to $200, contribute an additional degree of complexity to Dr. Khanna’s project work. Preemptible compute capacity offers the advantage of a consistent price not subject to dynamic demand pricing, as are other public cloud instances. PVMs are assigned to a job for a finite period of time but – here’s the rub – they can be revoked at any moment. While Dr. Khanna’s workflow was ideal for leveraging PVMs, since it consists of small, short-running jobs, PVMs can disappear at without warning.

In the case of Dr. Khanna’s ALS research work, said Jason Stowe, CEO of Cycle Computing said, “if you’re willing to getting rid of the node, but you’re able to use it during that timeframe at substantially lower cost, that allows you get a lot more computing bang for your buck. CycleCloud automates the process, taking care of nodes that go away, making sure the environment isn’t corrupted, and other technical aspects that we take care of so the user doesn’t have to.”

The simulation process is divided into two parts. The first step uses the Schrödinger LigPrep package, which converts 2D structures to the 3D format used in the next stage. This stage started with 4 GB of input data staged to an NFS filer. The output data was approximately 800KB and was stored on the NFS filer as well. To get the simulation done as efficiently as possible, the workload was split into 300 smaller jobs to assist in scaling the next stage of the workflow. In total, the first stage consumed 1500 core-hours of computation.

The Schrödinger Glide software package performs the second stage of the process, where the actual docking simulation is performed. Each of the 300 sub-jobs consists of four stages, each with an attendant prep stage. The total consumption was approximately 20,000 core-hours using 5,000 cores of n1-highcpu-16 instances. Each instance had 16 virtual cores with 60 gigabytes of RAM. The CycleCloud software dynamically sized the cluster based on the number of jobs in queue and replaced preempted instances.

Dr. Khanna’s research is the early stages of a process that, if successful, could take several years before reaching human clinical trials.

“The faster we can do this, the less time we have to wait for results, so we can go back and test it again and try to figure out what compounds are really binding,” she said, “the faster the process can move along.”

Dr. Khanna said plans are in place to increase the size of the pool of potential compounds, as well as include other proteins in the simulation to look for interactions that would not typically be seen until later in the process. The team will also simulate over the entire surface of the protein instead of just a known-active area unlocking “an amazing amount of power” in the search process, she said.

“That jump between docking to binding to biological testing takes a really long time, but I think we can move forward on that with this cloud computing capacity,” she said. “The mice data that we saw was really exciting…, you could see true significant changes with the mice. I can’t tell you we’ve discovered the greatest thing for ALS, but showing that if we take these small molecules and we can see improvement, even that is so significant.”

Dutch Startup Offers Immersive Cooling for Cloud, Edge and HPC Datacenter

Thu, 02/16/2017 - 19:53

HAARLEM, The Netherlands, Feb. 16, 2017 — Asperitas, cleantech startup from the Amsterdam area, one of the world’s datacentre hotspots, is introducing a unique solution based on a total liquid cooling concept called Immersed Computing.

After 1.5 years of research and development with an ecosystem of partners Asperitas is launching their first market ready solution, the AIC24, at the leading international industry event Data Centre World & Cloud Expo Europe.

The AIC24

The Asperitas AIC24 is at the centre of Immersed Computing. It is a closed system and the first water-cooled oil-immersion system which relies on natural convection for circulation of the dielectric liquid. This results in a fully self-contained and Plug and Play modular system. The AIC24 needs far less infrastructure than any other liquid installation, saving energy and costs on all levels of datacentre operations. The AIC24 is the most sustainable solution available for IT environments today. Ensuring the highest possible efficiency in availability, energy reduction and reuse, while increasing capacity. Greatly improving density, while saving energy at the same time.

The AIC24 is designed to ensure the highest possible continuity for cloud providers. Total immersion ensures no oxygen gets in touch with the IT components, preventing oxidation. Thermal shock is greatly reduced due to the high heat capacity of liquid. The immersed environment only has minor temperature fluctuations, greatly reducing stress by thermal expansion on micro-electronics. These factors eliminate the root cause for most of the physical degradation of micro-electronics over time.

Plug and Play green advanced computing anywhere

The AIC24 is Plug and Play. A single module requires only power, access to a water loop and data connectivity to operate. Combined with its silent workings, these limited requirements enable high flexibility in deployment sites and scenarios for the AIC24.

Two specially designed Convection Drives for forced water and natural flow of oil, are capable of transferring 24 kW of heat from the oil while keeping all the IT components at allowable operating temperatures.

Maximised IT capacity, the Asperitas Universal Cassette can contain multiple physical servers. Each module accommodates 24 AUC’s, as well as 2 Universal Switching Cassettes. This currently adds up to 48 immersed servers and 2 immersed switches.

Immersed Computing

Immersed Computing is a concept driven by sustainability, efficiency and flexibility and goes far beyond just technology. In many situations, Immersed Computing can save more than 50% of the total energy footprint. By using immersion, 10-45% of IT energy is reduced due to the lack of fans, while other energy consumers like cooling installations can achieve up to 95% energy reduction. It allows for warm water cooling which provides even more energy savings on cooling installations. One more benefit, Immersed Computing enables high temperature heat reuse.

Immersed Computing includes an optimised way of work, highly effective deployment, flexible choice of IT and drastic simplification of datacentre design. Offering great advantages on all levels of any datacentre value chain, Immersed Computing realises maximum results in Cloud, Private and Edge environments.

About Asperitas

Asperitas is a cleantech company focused on greening the datacentre industry by introducing immersed computing.

The Asperitas Development partners include University of Leeds, Aircraft Development and Systems Engineering (ADSE), Vienna Scientific Cluster, Super Micro, Schleifenbauer and Brink Industrial. Asperitas is furthermore recognised and supported by the Netherlands Enterprise Agency as a promising new cleantech company.

Data Analytics Gets the Spotlight in Distinguished Talk Series at ISC 2017

Thu, 02/16/2017 - 08:42

FRANKFURT, Germany, Feb. 16 — In a continuous effort to diversify topics at the ISC High Performance conference, the organizers are pleased to announce that two of this year’s presentations in the Distinguished Talk series will focus on data analytics in manufacturing and scientific applications.

The ISC 2017 Distinguished Talk series will offer five talks, spread over Tuesday, June 20 and Wednesday, June 21. The five-day technical program sessions will be held from Sunday, June 19 through Thursday, June 22. Over 3,000 attendees are expected at this year’s conference.

On Tuesday afternoon at 1:45 PM, cybernetics expert, Dr. Sabine Jeschke, who heads the Cybernetics Lab at the RWTH Aachen University, will deliver a talk about “Robots in Crowds – Robots and Clouds.” Jeschke’s presentation will be followed by one from physicist Kerstin Tackmann, from the German Electron Synchrotron (DESY) research center, who will discuss big data and machine learning techniques used for the ATLAS experiment at the Large Hadron Collider.

Jeschke’s research expertise lies in distributed artificial intelligence, robotics, automation, and virtual worlds, among other areas. In her talk, she will discuss new trends in mobile robotic systems, with special emphasis on the relationship between AI, cognitive systems and robotics. She will also present new paradigms for robotic platforms, for example, humanoids, robots on wheels, animal-like robots and industrial robots, with respect to their application areas and their physical realization.

In her abstract, she specifies the need to consider big data and its analytics as a critical aspect of robotics. At the same time, Jeschke also identifies how high performance computing will need to be applied to robotic systems. She will be sharing all of these topics and more with the ISC 2017 audience.

Tackmann, who will be speaking immediately after Jeschke, will give an overview of the ATLAS experiment, with particular attention to its enormous flow of data generated by the ATLAS detectors. She will present some of the experiment’s results, and give an overview of the technologies employed to store, search and retrieve experimental data and metadata, including the use of analytics tools and machine learning techniques.

The ATLAS experiment is one of the two multi-purpose experiments at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva. Since ATLAS began collecting data in 2009, it has been used to understand the processes described by the Standard Model of elementary particle physics, identify the Higgs boson, and search for particles and phenomena beyond the Standard Model.

Tackmann, who earned her PhD in Physics (experimental particle physics) from the University of Berkeley in California, has been involved in the ATLAS Experiment since 2011. She leads the Helmholtz Young Investigators Group Higgs Physics with Photons, which is a part of the ATLAS group at the DESY center.

ExxonMobil and NCSA Achieve Simulation Breakthrough

Thu, 02/16/2017 - 07:27

SPRING, Tex., Feb. 16 — ExxonMobil, working with the National Center for Supercomputing Applications (NCSA), has achieved a major breakthrough with proprietary software using more than four times the previous number of processors used on complex oil and gas reservoir simulation models to improve exploration and production results.

The breakthrough in parallel simulation used 716,800 processors, the equivalent of harnessing the power of 22,400 computers with 32 processors per computer. ExxonMobil geoscientists and engineers can now make better investment decisions by more efficiently predicting reservoir performance under geological uncertainty to assess a higher volume of alternative development plans in less time.

The record run resulted in data output thousands of times faster than typical oil and gas industry reservoir simulation. It was the largest number of processor counts reported by the oil and gas industry, and one of the largest simulations reported by industry in engineering disciplines such as aerospace and manufacturing.

“This breakthrough has unlocked new potential for ExxonMobil’s geoscientists and engineers to make more informed and timely decisions on the development and management of oil and gas reservoirs,” said Tom Schuessler, president of ExxonMobil Upstream Research Company. “As our industry looks for cost-effective and environmentally responsible ways to find and develop oil and gas fields, we rely on this type of technology to model the complex processes that govern the flow of oil, water and gas in various reservoirs.”

The major breakthrough in parallel simulation results in dramatic reductions in the amount of time previously taken to study oil and gas reservoirs. Reservoir simulation studies are used to guide decisions such as well placement, the design of facilities and development of operational strategies to minimize financial and environmental risk. To model complex processes accurately for the flow of oil, water, and natural gas in the reservoir, simulation software must solve a number of complex equations. Current reservoir management practices in the oil and gas industry are often hampered by the slow speed of reservoir simulation.

ExxonMobil’s scientists worked closely with the NCSA to benchmark a series of multi-million to billion cell models on NCSA’s Blue Waters supercomputer. This new reservoir simulation capability efficiently uses hundreds of thousands of processors simultaneously and will have dramatic impact on reservoir management workflows.

“NCSA’s Blue Waters sustained petascale system, which has benefited the open science community so tremendously, is also helping industry break through barriers in massively parallel computing,” said Bill Gropp, NCSA’s acting director. “NCSA is thrilled to have worked closely with ExxonMobil to achieve the kind of sustained performance that is so critical in advancing science and engineering.”

ExxonMobil’s collaboration with the NCSA required careful planning and optimization of all aspects of the reservoir simulator from input/output to improving communications across hundreds of thousands of processors. These efforts have delivered strong scalability on several processor counts ranging from more than 1,000 to nearly 717,000, the latter being the full capacity of NCSA’s Cray XE6 system.

Here’s What a Neural Net Looks Like On the Inside

Wed, 02/15/2017 - 12:54

Ever wonder what the inside of a machine learning model looks like? Today Graphcore released fascinating images that show how the computational graph concept maps to a new graph processor and graph programming framework it’s creating.

Graphcore is a UK-based startup that’s building a new processor, called the Intelligent Processing Unit (IPU), which is designed specifically to run machine learning workloads. Graphcore says systems that have its IPU processors, which will plug into traditional X86 servers via PCIe interfaces, will have more than 100x the memory bandwidth than scalar CPUs, and will outperform both CPUs and vector GPUs for emerging machine learning workloads for both training and scoring stages.

The company is also developing a software framework called Poplar that will abstract the machine learning application development process from the underlying IPU-based hardware. Poplar was written in C++ and will be able to take applications written in other frameworks, like TensorFlow and MXNet, and compile them into optimized code to execute on IPU-boosted hardware. It will feature C++ and Python interfaces.

All modern machine learning frameworks like TensorFlow, MxNet, Caffe, Theano, and Torch use the concept of a computational graph as an abstraction, says Graphcore’s Matt Fyles, who wrote today’s blog post.

“The graph compiler builds up an intermediate representation of the computational graph to be scheduled and deployed across one or many IPU devices,” Fyles writes. “The compiler can display this computational graph, so an application written at the level of a machine learning framework reveals an image of the computational graph which runs on the IPU.”

This is where the images come from. The image at the top of the page shows a graph based on the AlexNet architecture, which is a powerful deep neural network used in image classification workloads among others.

“Our Poplar graph compiler has converted a description of the network into a computational graph of 18.7 million vertices and 115.8 million edges,” Fyles writes. “This graph represents AlexNet as a highly-parallel execution plan for the IPU. The vertices of the graph represent computation processes and the edges represent communication between processes. The layers in the graph are labelled with the corresponding layers from the high level description of the network. The clearly visible clustering is the result of intensive communication between processes in each layer of the network, with lighter communication between layers.”

Graphcore also generated images of the graph execution plan a deep neural network built on Resnet, which Microsoft Research released in 2015. Graphcore was used to compile a 50-layer deep neural network composed of a graph execution plan with 3.22 million vertices and 6.21 million edges.

One of the unique aspects of the ResNet architecture is that it allows deep networks to be assembled from repeated section. Graphcore says its IPU only needs to define these sections once, and then can call them repeatedly, using the same code but with different “network weight data.”

“Deep networks of this style are executed very efficiently as the whole model can be permanently hosted on an IPU, escaping the external memory bottleneck which limits GPU performance,” the company says.

Finally, Graphcore shared a computational graph execution plan that involved time-series data gathered from astrophysicists working at the University of Illinois. The researchers used the MXnet DNN framework to analyze data collected from the LIGO gravitational wave detector, which looks for gravitational abnormalities caused by the presence of black holes. The image that Graphcore shared is the “full forward and backward pass of the neural network trained on the LIGO data to be used for signal analysis,” the company says.

“These images are striking because they look so much like a human brain scan once the complexity of the connections is revealed,” Fyles writes, “and they are incredibly beautiful too.”

Graphcore emerged from stealth mode last October, when it announced a $30 million Series A round to help finance development of products. Its machine learning (ML) and deep learning acceleration solutions include a PCIe card that plugs directly into a server’s bus.

Azure Edges AWS in Linpack Benchmark Study

Wed, 02/15/2017 - 09:43

The “when will clouds be ready for HPC” question has ebbed and flowed for years. It seems clear that for at least some workloads and on some clouds, the answer is now. HPC cloud specialist Nimbix, for example, focuses on providing fast interconnect, large memory, and heterogeneous architecture specifically tailored for HPC. The goliath public clouds have likewise steadily incorporated needed technology and (perhaps less decisively) pricing options.

A new study posted on arXiv.org last week – Comparative benchmarking of cloud computing vendors with High Performance Linpack – authored by Exabyte.io, an admittedly biased source, reports the answer is an unambiguous yes to the question of whether popular clouds can accommodate HPC and further examines some of the differences between a few of the major players.

“For high performance computing (HPC) workloads that traditionally required large and cost-intensive hardware procurement, the feasibility and advantages of cloud computing are still debated. In particular, it is often questioned whether software applications that require distributed memory can be efficiently run on ”commodity” compute infrastructure publicly available from cloud computing vendors,” write the authors, Mohammad Mohammadi, Timur Bazhirov of Exabyte.io.

“We benchmarked the performance of the best available computing hardware from public cloud providers with high performance Linpack. We optimized the benchmark for each computing environment and evaluated the relative performance for distributed memory calculations. We found Microsoft Azure to deliver the best results, and demonstrated that the performance per single computing core on public cloud to be comparable to modern traditional supercomputing systems.

“Based on our findings we suggest that the concept of high performance computing in the cloud is ready for a widespread adoption and can provide a viable and cost-efficient alternative to capital-intensive on- premises hardware deployments.”

Exabyte.io is a young company building a cloud-based environment to assist organizations with materials design – hence it has a horse in the race. Company marketing info on its website states, “Exabyte.io powers the adoption of high-performance cloud computing for design and discovery of advanced materials, devices and chemicals from nanoscale. We combine high fidelity simulation techniques, large-scale data analytics and machine learning tools into a hosted environment available for public, private and hybrid cloud deployments.”

Leaving its interest aside the study is interesting. Here’s a list of the cloud offerings evaluated:

The benchmarking was done using the High Performance Linpack (HPL) program, which solves a random system of linear equations, represented by a dense matrix, in double precision (64 bits) arithmetic on distributed-memory computers. “It does so through a two-dimensional block- cyclic data distribution, and right-looking variant of the LU factorization with row partial pivoting.” It is a portable and freely available software package.

Three different AWS scenarios were tested including– hyper-threaded, non-hyper-threaded, and non-hyper-threaded with placement groups. On Azure, three different instance types were used, F-series, A-series, and H-series. Compute1-60 instances were used on Rackspace. The benchmark was also run on NERSC Edison supercomputer with hyper-threading enabled. Edison, of course, is a Cray XC30, with a peak performance of 2.57 PFLOPS, 133,824 compute cores, 357 terabytes of memory, and 7.56 petabytes of disk, holding number 60 rank on the top500. Specific configurations shown below.

In many cases the performances were quite similar but each also had strengths and weaknesses. For example, network saturation at scale and slower processor clock speeds affected IBM Softlayer’s performance according to the study. The authors also noted: “AWS and Rackspace show a significant degree of parallel performance degradation, such that at 32 nodes the measured performance is about one-half of the peak value.”

The brief paper is best read in full for the details. The performance data for each of the clouds is presented. Below is a summary figure of cloud performances.

Figure 1: Speedup ratios (the ratios of maximum speedup Rmax to peak speedup Rpeak) against the number of nodes for all benchmarked cases. Speedup ratio for 1,2,4,8,16 and 32 nodes are investigated and given by points. Lines are drawn to guide the eye. The legend is as follows: AWS – Amazon Web Services in the default hyper-threaded regime; AWS-NHT – same, with hyperthreading disabled; AWS-NHT- PG – same, with placement group option enabled; AZ – Mi- crosoft Azure standard F16 instances; AZ-IB-A – same provider, A9 instances; AZ-IB-H – same provider, H16 instances; RS – Rackspace compute1-60 instances; SL – IBM/Softlayer virtual servers; NERSC – Edison computing facility of the National Energy Research Scientific Computing Center.

On balance, argue the authors, “Our results demonstrate that the current generation of publicly available cloud computing systems are capable of delivering comparable, if not better, performance than the top-tier traditional high performance computing systems. This fact confirms that cloud computing is already a viable and cost-effective alternative to traditional cost- intensive supercomputing procurement.”

LBNL Develops Machine Learning Tool for Alloy Research

Tue, 02/14/2017 - 10:48

New and interesting uses for machine learning seem to arise daily. Researchers from Lawrence Berkeley National Laboratory recently trained an algorithm to predict structural characteristics of certain metal alloys that slashes computational power usually required for such calculations. The new approach is expected to accelerate research of new advanced alloys for applications spanning automotive to aerospace and much more.

Their work – Predicting defect behavior in B2 intermetallics by merging ab initio modeling and machine learning – is published in a recent issue of Nature Computational Materials. As an extension of this proof-of-concept work, an open source Python toolkit for modeling point defects in semiconductors and insulators (PyCDT) has been developed.

Traditionally, researchers have used a computational quantum mechanical method known as density functional calculations to predict what kinds of defects can be formed in a given structure and how they affect the material’s properties. This approach is computationally challenging and has limited its use, according to an article on the work posted on the NERSC site.

“Density functional calculations work well if you are modeling one small unit, but if you want to make your modeling cell bigger the computational power required to do this increases substantially,” says Bharat Medasani, a former Berkeley Lab postdoc and lead author of the paper. “And because it is computationally expensive to model defects in a single material, doing this kind of brute force modeling for tens of thousands of materials is not feasible.”

Medasani and his colleagues developed and trained machine learning algorithms to predict point defects in intermetallic compounds, focusing on the widely observed B2 crystal structure. Initially, they selected a sample of 100 of these compounds from the Materials Project Database and ran density functional calculations on supercomputers at the National Energy Research Scientific Computing Center (NERSC), a DOE Office of Science User Facility at Berkeley Lab, to identify their defects.

The overall result is it is no longer necessary to run costly first principle calculations to identify defect properties for every new metallic compound, say the researchers.

“This tool enables us to predict metallic defects faster and robustly, which will in turn accelerate materials design,” says Kristin Persson, a Berkeley Lab Scientist and Director of the Materials Project, an initiative aimed at drastically reducing the time needed to invent new materials by providing open web-based access to computed information on known and predicted materials.
