VSC-3: Performance Reports (Allinea)

Synopsis:

perf-report is a lightweight profiling tool that provides basic information about where the computing time is actually spent in a given application. It is developed by Allinea http://www.allinea.com/products/allinea-performance-reports and very easy to use, i.e. by simply inserting the call to perf-report prior to the usual execution of the program.

Usage:

For example, analyzing a simple MPI job could be done with the help of the following submit script to SLURM

 #!/bin/bash
#
#SBATCH -J prflng
#SBATCH -N 2
#SBATCH -L allinea@vsc
#SBATCH --time=00:10:00

module purge
