Launcher: A simple tool for executing high throughput computing workloads

Abstract

Launcher (Wilson and Fonner 2014, Wilson (2016), Wilson (2017)) is a utility for performing simple, data parallel, high throughput computing (HTC) workflows on clusters, massively parallel processor (MPP) systems, workgroups of computers, and personal machines. It can be easily run from userspace or installed for system-wide use on shared resources. Launcher will perform automatic process binding on multi-/many-core architectures where hwloc (“Portable Hardware Locality (Hwloc)” n.d.) is installed.
