Re: [OMPI users] configuring with --enable-mpi-profile option

[George Bosilca]

I think you're expect something that the MPI profiling interface is not supposed to provide you. There is no tool to dump or print any profile information by default (and it is not mandated by the standard). What this option does, is compile the profiling interface (as defined by the MPI standard) allowing external tools to gather information about the MPI application.

But you need an extra tool.

1) Once build is complete, how do I specify profile name and location in the “mpirun” command? Do I have to set any flags with the “mpirun” command to view profile? 2) If vampire trace by default is built with openmpi, if I set VT_CC flag for compiling my application, where I can view “.vtf” files after a parallel run ?
