Radio Free HPC Looks at the New Coral-2 RFP for Exascale Computers

In this podcast, the Radio Free HPC team looks at the new Department of Energy’s RFP for Exascale Computers. “As far as predictions go, Dan thinks one machine will go to IBM and the other will go to Intel. Rich thinks HPE will win one of the bids with an ARM-based system designed around The Machine memory-centric architecture. They have a wager, so listen in to find out where the smart money is.”

Using the Titan Supercomputer to Develop 50,000 Years of Flood Risk Scenarios

Dag Lohmann from KatRisk gave this talk at the HPC User Forum in Tucson. “In 2012, a small Berkeley, California, startup called KatRisk set out to improve the quality of worldwide flood risk maps. The team wanted to create large-scale, high-resolution maps to help insurance companies evaluate flood risk on the scale of city blocks and buildings, something that had never been done. Through the OLCF’s industrial partnership program, KatRisk received 5 million processor hours on Titan.”

Video: DOE Issues RFP for Exascale Supercomputers

Today Energy Secretary Rick Perry announced the DOE has issued a Request for Proposal for 2-3 Exascale machines. “Called CORAL-2, this RFP is for up to $1.8 billion and is completely separate from the $320 million allocated for the Exascale Computing Project in the FY 2018 budget. Those funds are mostly focused at application development and software technology for an exascale software stack.”

Video: Powering the Road to National HPC Leadership

Jack Wells from ORNL gave this talk at the 2018 OpenPOWER Summit. “The Summit supercomputer coming to Oak Ridge is the next leap in leadership-class computing systems for open science. Summit will have a hybrid architecture, and each node will contain multiple IBM POWER9 CPUs and NVIDIA Volta GPUs all connected together with NVIDIA’s high-speed NVLink. Each node will have over half a terabyte of coherent memory (high bandwidth memory + DDR4) addressable by all CPUs and GPUs plus 800GB of non-volatile RAM that can be used as a burst buffer or as extended memory.”

Agenda Posted: OpenPOWER 2018 Summit in Las Vegas

The OpenPOWER Summit has posted its speaker agenda. Held in conjunction with IBM Think 2018, the event takes place March 19 in Las Vegas. “The OpenPOWER Foundation is an open technical community based on the POWER architecture, enabling collaborative development and opportunity for member differentiation and industry growth. The goal of the OpenPOWER Foundation is to create an open ecosystem, using the POWER Architecture to share expertise, investment, and server-class intellectual property to serve the evolving needs of customers and industry.”

Radio Free HPC Looks at Diverging Chip Architectures in the Wake of Spectre and Meltdown

In this podcast, the Radio Free HPC team looks at the tradeoff between chip performance and security. In the aftermath of the recently disclosed Spectre and Meltdown exploits, Cryptograpy guru Paul Kocher from Rambus is calling for a divergence in processor architectures:

Application Readiness Projects for the Summit Supercomputer Architecture

Dr. Tjerk P. Straatsma from ORNL gave this talk at SC17. “The Center for Accelerated Application Readiness (CAAR) projects are using an Early Access Power8+/Pascal system named SummitDev to prepare for the Power9/Volta system Summit. This presentation highlights achievements on this system, and the experience of the teams that will be a valuable resource for other development teams.”

Video: Lustre File System on ARM

Carlos Thomaz from DDN gave this talk at LAD’17 in Paris. “With the first set of Arm-based HPC servers debuting at SC17 in Denver, the platform is being evaluated for Lustre performance by a number of other organizations including Cray, DDN, and ORNL.”

CesgaHack GPU Hackathon Returns to Spain in March

The Galicia Supercomputing Center (CESGA) and Appentra Solutions will host a GPU Hackathon March 5-9 in Santiago de Compostela. “CesgaHack18 aims to help scientists and developers accelerate the execution of their scientific simulation applications using the hardware, software and a team of expert mentors in optimization, parallelization and execution of simulation programs.”

Video: Thomas Zacharia from ORNL Testifies at House Hearing on the Need for Supercomputing

In this video, Thomas Zacharia from ORNL testifies before the House Energy and Commerce hearing on DOE Modernization. “At the OLCF, we are deploying a system that may well be the world’s most powerful supercomputer when it begins operating later this year. Summit will be at least five times as powerful as Titan. It will also be an exceptional resource for deep learning, with the potential to address challenging data analytics problems in a number of scientific domains. Summit is among the products of CORAL, the Collaboration of Oak Ridge, Argonne, and Livermore.”
