Running MPI applications in Singularity and Docker containers. ... The Message Passing Interface (MPI) is one of the frameworks used in high-performance computing (HPC) for a wide variety of parallel computing architectures. It can be used for running applications ... Running MPI applications in Singularity and Docker containers. ... MPI Apps with Singularity and Docker ... MPI Apps with Singularity and Docker

We discuss how two tools for processor and memory affinity – taskset and numactl – can be used in OpenMP and Message Passing Interface (MPI) applications to control how processes are moved around ... with various HPC applications. In this article, I present examples for (1) serial applications, (2) OpenMP applications, and (3) MPI applications. I’ll use the same architecture as before: a single-socket system ...
