Performing I/O in a logical and coherent manner from disparate processes is not easy. It’s even more difficult to perform I/O in parallel. I’ll begin

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 ...
