Building and running containers on HPC systems - a (not at all) comprehensive talk”

On Friday May 10 1 - 3pm ET (10am - 12pm PT), the Education and Training Seminar Series presents Subil Abraham who will speak about “Building and running containers on HPC systems - a (not at all) comprehensive talk”.

Abstract: The use of containers on a typical HPC system is a little different from running it on your personal computer or in something like Kubernetes. You want it to be up and running in a way similar to the typical applications that are built on HPC systems and run via a scheduler, and still perform as good as the bare metal applications. Your users might need to be able to build their container images on your HPC system (on your login nodes or build nodes without root privileges) so that they are being built on the same environment as the typical applications, and especially important if your HPC system has an uncommon microarchitecture like ARM or PowerPC. Getting the performance needed for MPI enabled applications would mean hunting for your system’s MPI libraries and binding them into your container so that the application can link to it. And that’s just a few of the factors to consider. In this talk I’ll go over what we do to solve these and other problems on the HPC systems at ORNL and what lessons we learned in the process that can apply to your efforts to use containers at your HPC center.

Bio: Subil Abraham is an HPC Engineer in the Oak Ridge Leadership Computing Facility in the Oak Ridge National Laboratory. He spends half his time solving problems for scientists who contact the OLCF help desk with issues they have on the supercomputers, the other half testing containers and advocating for container functionality on the various systems the OLCF supports, and the third half is spent doing various other odd work in user training and user advocacy while being bad at math.

Intended Audience: Engineers looking to support containers at their HPC center, and users looking into using containers in their HPC work.
