Slidecast: Rethinking Server Power Architecture in the Post-Silicon World

In this slidecast, Alexander Lidow from EPC describes how the company is leading a technological revolution with Gallium Nitride (GaN). More efficient than silicon as a basis for electronics, GaN could save huge amounts of energy in the datacenter and has the potential to fuel the computer industry beyond Moore’s Law. “Due to its superior switching speeds and smaller footprint, Texas Instruments is working with EPC to build a simpler topology that achieves better efficiency with smaller footprints and significantly lower cost.”

Radio Free HPC Looks at What Chip Architectures Need to Succeed

In this podcast, the Radio Free HPC team welcomes Shahin Khan from OrionX to a discussion on chip architectures for HPC. “More and more new alternative architectures were in evidence at ISC in Germany this year, but what does it take for a chip architecture to be a winner? Looking back, chips like DEC Alpha had many advantages over the competition, but it did not survive.”

Podcast: Micron’s Steve Pawlowski on the Latest Memory Trends for HPC

In this podcast from ISC 2016 in Frankfurt, Steve Pawlowski from Micron discusses the latest memory technology trends for high performance computing. “When you look at a technology like 3D XPoint and some of the new materials the industry is looking at, those latencies are becoming more DRAM-like, which makes them a more attractive option to look at. Is there a way we can actually inject persistent memory that’s fairly high-performance so we don’t take a performance hit but we can certainly increase the capacity on a cost-per-bit basis versus what we have today?”

Podcast: Supercomputing Better Ways to Produce Gamma Rays

In this podcast, researchers from the University of Texas at Austin discuss how they are using TACC supercomputers to find a new way to make controlled beams of gamma rays. “The simulations done on the Stampede and Lonestar systems at TACC will guide a real experiment later this summer in 2016 with the recently upgraded Texas Petawatt Laser, one of the most powerful in the world. The scientists say the quest for producing gamma rays from non-radioactive materials will advance basic understanding of things like the inside of stars. What’s more, gamma rays are used by hospitals to eradicate cancer, image the brain, and they’re used to scan cargo containers for terrorist materials. Unfortunately no one has yet been able to produce gamma ray beams from non-radioactive sources. These scientists hope to change that.”

Podcast: What a Supercomputer Does

In this WBEZ podcast, Katherine Riley from Argonne explains what a supercomputer does. “Argonne National Laboratory is celebrating its 70th anniversary. The science and engineering research center has had a prominent place in historical research developments. They’re currently in the process of installing their newewst supercomputer, Theta.”

Slidecast: Announcing the Nvidia Tesla P100 for PCIe Servers

In this slidecast, Marc Hamilton from describes the Nvidia Tesla P100 for PCIe Servers. “The Tesla P100 for PCIe is available in a standard PCIe form factor and is compatible with today’s GPU-accelerated servers. It is optimized to power the most computationally intensive AI and HPC data center applications. A single Tesla P100-powered server delivers higher performance than 50 CPU-only server nodes when running the AMBER molecular dynamics code, and is faster than 32 CPU-only nodes when running the VASP material science applications.”

Radio Free HPC Looks at Sunway TaihuLight – the World’s Fastest Supercomputer

In this podcast, Shahin Khan from OrionX joins the Radio Free HPC team for a look at the new TOP500 list of the world’s fastest supercomputers. “The 93 Petaflop Sunway TaihuLight supercomputer is not a one-time effort from China. Not only do they now have the two top two supercomputers, China also sponsors the world’s largest state-sponsored Student Cluster Competition with over 170 university teams. The takeaway from today; China is serious about supercomputing, they are in it for the long haul, and they are willing to write the checks to make it happen.”

Slidecast: Announcing Mellanox ConnectX-5 100G InfiniBand Adapter

“Today, scalable compute and storage systems suffer from data bottlenecks that limit research, product development, and constrain application services. ConnectX-5 will help unleash business potential with faster, more effective, real-time data processing and analytics. With its smart offloading, ConnectX-5 will enable dramatic increases in CPU, GPU and FPGA performance that will enhance effectiveness and maximize the return on data centers’ investment.”

Podcast: Laconia Supercomputer Coming to MSU

In this WKAR podcast, Andy Keen from Michigan State University describes MSU’s new Laconia supercomputer. The $3-million system is part of a cluster that’s run by their ICER High Performance Computing Center. “It’s an exciting time for the computational sciences at MSU,” said iCER Director Kennie Merz. “Our researchers are poised to tackle transformative problems ranging from the discovery of new drugs to understanding the universe we live in.”

Podcast: CUDA Programming for GPUs

In this Programming Throwdown podcast, Mark Harris from Nvidia describes Cuda programming for GPUs. “CUDA is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for GPU computing with CUDA.”
