NVIDIA Releases Code for Accelerated Machine Learning

Today NVIDIA made a number of announcements centered around Machine Learning software at the Computer Vision and Pattern Recognition Conference in Salt Lake City. “NVIDIA is kicking off the conference by demonstrating an early release of Apex, an open-source PyTorch extension that helps users maximize deep learning training performance on NVIDIA Volta GPUs. Inspired by state of the art mixed precision training in translational networks, sentiment analysis, and image classification, NVIDIA PyTorch developers have created tools bringing these methods to all levels of PyTorch users.”

Virtualizing AI & HPC Workloads with vSphere

In this video from the Dell EMC HPC Community Meeting, Josh Simons from VMware describes why more customers are moving their HPC & AI workloads to virtualized environments using vSphere. “With VMware, you can capture the benefits of virtualization for HPC workloads while delivering performance that is comparable to bare-metal. Our approach to virtualizing HPC adds a level of flexibility, operational efficiency, agility and security that cannot be achieved in bare-metal environments—enabling faster time to insights and discovery.”

Let’s Talk Exascale: Optimizing I/O at the ADIOS Project

In this episode of Let’s Talk Exascale, researchers from the ADIOS project describe how they are optimizing I/O on exascale architectures and making the code easily maintainable, sustainable, and extensible, while ensuring its performance and scalability. “The Adaptable I/O System (ADIOS) project in the ECP supports exascale applications by addressing their data management and in situ analysis needs.”

ARM goes Big: HPE Builds Petaflop Supercomputer for Sandia

Today HPE announced plans to deliver the world’s largest Arm supercomputer. As part of the Vanguard program, Astra, the new Arm-based system, will be used by the NNSA to run advanced modeling and simulation workloads for addressing areas such as national security, energy and science. “By introducing Arm processors with the HPE Apollo 70, a purpose-built HPC architecture, we are bringing powerful elements, like optimal memory performance and greater density, to supercomputers that existing technologies in the market cannot match,” said Mike Vildibill, vice president, Advanced Technologies Group, HPE.

Video: Calligo Technologies Demonstrates Posit Computing Implementation

Anantha Kinnal from Calligo Technologies gave this talk at the ConGA conference for Next Generation Arithmetic. “CalligoTech, based in Bangalore – India, built and demonstrated World’s First Posit-enabled System at the CoNGA track at Supercomputing Asia’18, Singapore. Our primary objective was to build a System capable of performing basic arithmetic operations using Posit Number System and capable of running existing C programs.”

Video: Announcing Summit – World’s Fastest Supercomputer with 200 Petaflops of Performance

Today Energy Secretary Rick Perry unveiled Summit, the world’s most powerful supercomputer. Powered by IBM POWER9 processors, 27,648 NVIDIA GPUs, and Mellanox InfiniBand, the Summit supercomputer is also the first Exaop AI system on the planet. “This massive machine, powered by 27,648 of our Volta GPUs, can perform more than three exaops, or three billion billion calculations per second,” writes Ian Buck on the NVIDIA blog. “That’s more than 100 times faster than Titan, previously the fastest U.S. supercomputer, completed just five years ago. And 95 percent of that computing power comes from GPUs.”

Supercomputing how Fish Save Energy Swimming in Schools

Over at CSCS, Simone Ulmer writes that researchers at ETH Zurich have clarified the previously unresolved question of whether fish save energy by swimming together in schools. They achieved this by simulating the complex physics on the supercomputer ‘Piz Daint’ and combining detailed flow simulations with a reinforcement learning algorithm for the first time. “In their simulations, they have not examined every aspect involved in the efficient swimming behavior of fish. However, it is clear that the developed algorithms and physics learned can be transferred into autonomously swimming or flying robots.”

The Simulation of the Behavior of the Human Brain using CUDA

Pedro Valero-Lara from BSC gave this talk at the GPU Technology Conference. “The attendees can learn about how the behavior of Human Brain is simulated by using current computers, and the different challenges which the implementation has to deal with. We cover the main steps of the simulation and the methodologies behind this simulation. In particular we highlight and focus on those transformations and optimizations carried out to achieve a good performance on NVIDIA GPUs.”

Quantum Computing in China: Progress on a Superconducting Multi-Qubits System

Dr. Xiaobo Zhu from China’s University of Science and Technology gave this talk at the HPC User Forum in Tucson. “CAS-Alibaba Quantum Computing Laboratory introduces quantum technology into computing sciences, aiming to manufacture high-speed quantum computers, and propelling quantum revolution in the computing world. This research has resulted in a Quantum Computing Cloud powered by a quantum processor which includes 11 superconducting qubits. This superconducting quantum chip works at extreme temperatures as low as 10mk (or -273.14℃).”
