Super-Connecting the World’s Number One Supercomputers - Scot Schultz, Mellanox Technologies

Mellanox continues leadership as the best interconnect worldwide for both HPC and AI. With the latest intelligent interconnect devices, such as Mellanox Quantum HDR 200Gb/s and ConnectX-6 are enabling the next generation of in-network co-processing. With a more effective mapping of communication between devices in the system dramatically increases system performance.

Architecture Effects When Interacting with GPU Technologies - Christopher M. Sullivan, Oregon State University

Oregon State University’s Center for Genome Research and Biocomputing (CGRB) works closely with its users to determine the best computing platform for computational research. In the past several years we have seen many differences associated with architecture and GPU interactions. As we continued our testing we found tremendous benefits from using the OpenPOWER platform with Power9 processors and NVIDIA GPU. In an effort to truly determine the best platform for different types of GPU processing we created a set of test. We will be showing all the current data comparing some of the most bleeding-edge platforms and a demo of the machines racing each other. Our goal is to provide users with the ability to bring online the best platform for the work they are planning with GPU technology.

OpenPower Solution Builder Community - John Pace, Mark III & Christopher Sullivan, Oregon State University

The OpenPower Solution Builder Community is for those who design, implement, operate and maintain Power and OpenPower solution stacks. The Group is self-governing and provides a means for builders to share insights and innovation. There are three primary elements 1) questions & answers and pointers to relevant information, 2) best practices on building hardware-software solution stacks and reference architectures, 3) innovations of applications, libraries, methods, and approaches. The initial focus is solution stacks around the IBM POWER9 AC922 integrated GPU Server but will expand to additional systems and workloads. You do not need to be an OpenPower member to participate. This talk will discuss the community formation, topics that are active, and will solicit participation.

Developing Applications using Acceleration Hardware on Power - Gerrit Huizenga, IBM

This session will share the goals of the newly chartered Accelerated Application Ecosystem Working Group, which will help identify resources needed when porting accelerated applications to Power specific hardware accelerators. This session will provide an overview of some of the available accelerators, some of the existing porting resources, and solicit information from ISVs and software developers on any gaps in the software ecosystem today.
