Usage

First load the related software module

module load mpip

which will set the '$MPIP_HOME' variable to the latest mpiP installation path.

The behaviour of mpiP is controlled by options provided via the `MPIP` environment variable. See the mpiP documentation for a detailed description of all options.

A good starting point is the following:

export MPIP="-t 10.0 -k 2"

Finally run your application with the mpiP profiling library preloaded:

LD_PRELOAD=$MPIP_HOME/lib/libmpiP.so mpirun <your_app and options>

This will create a single file with file extension `.mpiP` in the folder including the profiling data.
