Paraver is a GUI-based performance visualisation and analysis tool that can be used to analyze parallel programs using MPI, OpenMP and MPI & OpenMP (Mixed-Mode).

poe.realmust be used rather than

poeis a script which points to the executable
export PARAVER_HOME = /usr/local/packages/paraver
During the run, Paraver will have created a temporary trace file for each process (*.mpit and *.sim files). After the run has completed the user must submit an instruction to pack the individual profile files into one global output. This is undertaken by issuing the command:
$PARAVER_HOME/bin/ompi2prv *.mpit -s *.sym -o trace_prm.prv
