A Performance Comparison of Different MPI Implementations on an ARM HPC System
August 28, 2019 by
Nicholas Brown from EPCC gave this talk at the MVAPICH User Group. “In this talk I will describe work we have done in exploring the performance properties of MVAPICH, OpenMPI and MPT on one of these systems, Fulhame, which is an HPE Apollo 70-based system with 64 nodes of Cavium ThunderX2 ARM processors and Mellanox InfiniBand interconnect. In order to take advantage of these systems most effectively, it is very important to understand the performance that different MPI implementations can provide and any further opportunities to optimize these.”

Features and releases for Microsoft Azure and Amazon AWS will also be presented. Current status and future plans for OSU INAM, OMB, and Best Practices Page will also be presented.”
Video: InfiniBand In-Network Computing Technology and Roadmap
August 25, 2019 by
Gilad Shainer from Mellanox gave this talk at the MVAPICH User Group. “In-Network Computing transforms the data center interconnect to become a “distributed CPU”, and “distributed memory”, enables to overcome performance barriers and to enable faster and more scalable data analysis. These technologies are in use at some of the recent large scale supercomputers around the world, including the top TOP500 platforms. The session will discuss the InfiniBand In-Network Computing technology and performance results, as well as view to future roadmap.”

Mellanox Rocks the TOP500 with Ethernet and InfiniBand
June 20, 2019 by
Today Mellanox announced that the company’s InfiniBand solutions accelerate six of the top ten HPC and AI Supercomputers on the June TOP500 list. The six systems Mellanox accelerates include the top three, and four of the top five: The fastest supercomputer in the world at Oak Ridge National Laboratory, #2 at Lawrence Livermore National Laboratory, #3 at Wuxi Supercomputing Center in China, #5 at Texas Advanced Computing Center, #8 at Japan’s Advanced Industrial Science and Technology, and #10 at Lawrence Livermore National Laboratory. “HDR 200G InfiniBand, the fastest and most advanced interconnect technology, makes its debut on the list, accelerating four supercomputers worldwide, including the fifth top-ranked supercomputer in the world located at the Texas Advanced Computing Center, which also represents the fastest supercomputer built in 2019.”
Agenda Posted: Exacomm 2019 Workshop at ISC High Performance
June 5, 2019 by
“The goal of this workshop is to bring together researchers and software/hardware designers from academia, industry and national laboratories who are involved in creating network-based computing solutions for extreme scale architectures. The objectives of this workshop will be to share the experiences of the members of this community and to learn the opportunities and challenges in the design trends for exascale communication architectures.”
Radio Free HPC Ponders Amdahl’s Law, GPUs, and the ASC19 Student Cluster Competition
June 3, 2019 by
In this podcast, the Radio Free HPC team reviews the results of the ASC19 Student Cluster Competition and HPC workshop in China. “For the first time, a non-mainland-Chinese team wins the top spot. Taiwan takes the gold in part by their stellar performance in HPCG benchmark where they achieved 2 TFlops, some 25% better than the 2nd best team. The system was a 5-node cluster with Infiniband FDR interconnect.”
Scalable and Distributed DNN Training on Modern HPC Systems
May 31, 2019 by
DK Panda from Ohio State University gave this talk at the Swiss HPC Conference. “We will provide an overview of interesting trends in DNN design and how cutting-edge hardware architectures are playing a key role in moving the field forward. We will also present an overview of different DNN architectures and DL frameworks. Most DL frameworks started with a single-node/single-GPU design.”
