Using the Launcher for Executing High Throughput Workloads

Launcher is a simple utility which enables the execution of high throughput computing workloads on managed HPC systems quickly and with as little effort as possible on the part of the user. Basic usage of the Launcher is straightforward, but Launcher provides several more advanced capabilities including use of Intel® Xeon Phi™ coprocessor cards and task binding support for multi-/many-core architectures. We step through the processes of setting up a basic Launcher job, including creating a job file, setting appropriate environment variables, and using scheduler integration. We also describe how to enable use of the Intel® Xeon Phi™ coprocessor cards, take advantage of Launcher's task binding system, and execute many parallel (OpenMP/MPI) applications at once.
