Call for Participation: OSC Statewide User Group Conference in October

The Ohio Supercomputer Center Statewide Users Group (SUG) has issued its Call for Participation. Featuring a talk on OSC’s pending Pitzer cluster, the event takes place Oct. 4 in Columbus, Ohio. The purposes of the SUG conference are to foster connections, update OSC’s user base on OSC’s direction, highlight new scientific developments produced using OSC resources, and obtain constructive feedback as to the future of OSC and our role in supporting science across Ohio. “We will have a flash talk and poster session to highlight the research and emerging ideas from OSC clients. Talks and posters will be selected from abstracts submitted via the registration form. We encourage posters by students just starting their work, to show creative ideas on how high-performance computing will enhance their research.”

Extreme Computing for Extreme Adaptive Optics: The Key to Finding Life Outside our Solar System

Hatem Ltaief from KAUST gave this talk at PASC18. “The real-time correction of telescopic images in the search for exoplanets is highly sensitive to atmospheric aberrations. The pseudo-inverse algorithm is an efficient mathematical method to filter out these turbulences. We introduce a new partial singular value decomposition (SVD) algorithm based on QR-based Diagonally Weighted Halley (QDWH) iteration for the pseudo-inverse method of adaptive optics. The pseudo-inverse simulation code will be deployed on-sky for the Subaru telescope during observation nights scheduled early 2018.”

Lenovo Takes the TOP500 with Liquid Cooling at ISC 2018

In this video from ISC 2018, Rick Koopman from Lenovo describes the company’s latest HPC innovations including their new Neptune liquid cooling technology. Lenovo is the world’s largest TOP500 supercomputing provider measured by the number of systems ranked on the TOP500 list. 117 of the 500 most powerful supercomputers included in the TOP500 are Lenovo installations, meaning nearly one out of every four systems (23.4 percent) on the prestigious list is a Lenovo solution.

One Stop Systems rolls out Magma ExpressBox eGPU with Thunderbolt 3

Today One Stop Systems introduced the Magma ExpressBox 3T-V3-eGPU, a new external graphics card solution with Thunderbolt 3. The ExpressBox 3T-V3-eGPU can transform both computers and laptops with Thunderbolt 3 connections into powerful workstations. “We’re committed to providing mobile professionals with the latest technologies for performing AI, CAE and rendering applications,” said Steve Cooper, CEO of OSS. “Our new ExpressBox 3T-V3-eGPU, like all of our Magma ExpressBox expansion products, enables professionals to remain mobile without sacrificing office workstation performance, but now takes it to a whole new level with NVIDIA technology.”

Training Generative Adversarial Models over Distributed Computing Systems

Gul Rukh Khattak from CERN gave this talk at PASC18. “We use a dataset composed of the energy deposition from electron, photons, charged and neutral hadrons in a fine grained digital calorimeter. The training of these models is quite computing intensive, even with the help of GPGPU, and we propose a method to train them over multiple nodes and GPGPU using a standard message passing interface. We report on the scalings of time-to-solution.”

PASC18 Panel Discussion Big Data vs. Fast Computation

“The panelists will discuss the critical challenges facing key HPC application areas in the next 5-10 years, based on a mix of knowledge and speculation. They will explore whether we need to make radical changes to our practices, methods, tools, and techniques to be able to use modern resources and make faster and bigger progress on our scientific problems.”

Ubercloud Posts 2018 Compendium of HPC Cloud Case Studies

Our friends at the UberCloud have published their 2018 Compendium of HPC Cloud Case Studies. “The Annual UberCloud Compendium of Case Studies is out! This is the 5th edition of this set of case studies relating to the world of Technical Computing. This year’s collection features case studies based on 13 select UberCloud Experiments, and the whole project is sponsored once again by Hewlett Packard Enterprise and Intel.”

Radio Free HPC Looks at China’s Exascale System Prototypes

In this podcast, the Radio Free HPC team looks at China’s new ARM-based Exascale supercomputer prototype. “The Sunway exascale computer prototype is very much like a concept car that can run on road,” said Yang Meihong, director of the National Supercomputing Center in Jinan. “We expect to build the exascale computer in the second half of 2020 or the first half of 2021.”

Video: Recent Results and Open Problems for Resilience at Scale

In this video from PASC18, Yves Robert from École normale supérieure de Lyon in France presents: Recent Results and Open Problems for Resilience at Scale. “The talk will address the following three questions: (i) fail-stop errors: checkpointing or replication or both? (ii) silent errors: application-specific detectors or plain old trustworthy replication? In terms of workflows: how to avoid checkpointing every task?”

Job of the Week: HPC Architecture and Performance Engineer at LBNL

Lawrence Berkeley National Lab is seeking an HPC Architecture and Performance Engineer in our Job of the Week. “Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC) has an opening for a Computer Systems Engineer 3. The incumbent will contribute to an on-going Advanced Technology Group (ATG) group effort to develop a complete understanding of the issues that lead to improved application and computer system performance on extreme-scale advanced architectures. As a team member, they will contribute to efforts for NERSC in evaluating existing and emerging High Performance Computing (HPC) systems by analyzing the performance characteristics of leading-edge DOE Office of Science application codes.”
