2021 ECP Annual Meeting - HPC System and Software Testing via Buildtest

This talk was held on April 15, 2021 as part of the 2021 ECP Annual Meeting.  

HPC computing environment is a tightly coupled system that includes a cluster of nodes and accelerators interconnected with a high-speed interconnect, a parallel file system, multiple storage tiers, a job scheduler and a software stack for users to run their workflows. This environment is highly interdependent, therefore it is essential to regularly test various components of the HPC system and the software stack. There is significant progress in software build frameworks (spack, easybuild) for installing software packages for HPC systems, however there is little consensus on the testing front.
