Dell Technologies HPC Community Event
About the Event
High performance computing systems today are able achieve high performance by aggregating the performance of CPUs, and sometimes also GPUs or accelerators. This is most often achieved by clustering servers with high end processors (and accelerators) to create a virtual supercomputer with the combined theoretical peak performance of all the servers. The network connecting these servers, or interconnect, is thus fundamental to HPC clusters, and must itself be very high performance to enable the HPC cluster to allow parallel applications to scale well. In most HPC clusters and workloads, the network (or second network) is also crucial for facilitating high performance IO that can keep up with the demands of HPC applications. For HPC systems, this means latency, bandwidth, topology, NICs and routers, protocols, and more must be designed and implemented efficiently to realize the potential of HPC clusters.
In this presentation, Jeff Kirk, an HPC & AI Technologist in the CTIO Office at Dell Technologies, will give a basic tutorial on types and characteristics of networks, and what HPC customers should understand to make wise design choices for their workloads.
About the Speaker
Jeff Kirk, HPC & AI Technologist in CTIO Office, Dell Technologies
Jeff has spent his career working at the leading edge of computing and networking. Jeff is currently working in the Dell Technologies ISG CTIO Office and is an HPC and AI Technology Strategist where he has helped grow the HPC program with a new vision, strategy, business development efforts, and new partnerships and solutions. Prior to joining Dell EMC, Jeff worked at several cutting edge semi-conductor companies. At AMD he specialized in superscalar RISC and x86 platforms for high performance computation (1999). At Mellanox he worked on some of the first InfiniBand HPC installations, including the Virginia Tech cluster that reached number three on the top 500 (Big Mac) using Apple workstations (Nov 2004). While at Mellanox he supported Dr. D.K. Panda and the first implementation of MVAPICH at his alma mater, The Ohio State University. Later at Solarflare his focus was OS bypass technology and financial markets (2010).
