Monthly Topic: Wraprun
Wraprun is a wrapper utility for ALPS/Aprun that bundles tasks into single aprun calls. It permits launching multiple independent instances of an application on singular nodes or even multiple unique applications on several nodes in a single aprun call. Bundling tasks reduces aprun overhead and allows more tasks to be started per batch job. Wraprun works with both MPI-aware and serial executables. We will give an overview of how it works, how to use it, and its limitations.
Speakers: Adam Simpson and Matt Belhorn
