+===== VSC-3: Performance Report (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 simple 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 [[doku:slurm|SLURM]]
+   #!/bin/bash
+   #
+   #SBATCH -J prflng
+   #SBATCH -N 2
+   #SBATCH --time=00:10:00
+   module purge
+   module load intel-mpi/5
+   module load allinea/5.10
+   perf-report mpirun -np 32 a.out
+This produces .edf and .trc files. Then one has to
+merge these files via:
+<code>
+tau_merge -e events.*.edf -m vasp_events.edf tautrace.*.0.0.trc vasp.trc
+</code>
+and finally the 'vasp.trc' and the 'vasp_events.edf' files need to
+be converted into .slog2 format:
+<code>
+tau2slog2 vasp.trc vasp_events.edf -o vasp.slog2
+</code>
+This file (vasp.slog2) can be visualized with jumpshot.
+===== Visualization of Profiles and Traces =====
+==== VAMPIR ====
+Currently a demo version of [[http://www.vampir.eu|VAMPIR]] is installed on VSC-1. It can visualize VAMPIRTRACE files, as well as other formats such as OTF
+Location on VSC-1: ''/opt/vampir''
+==== JUMPSHOT and PARAPROF ====
+Both are installed together with TAU.
