But if openmpi is installed, I can automatically instrument my application with Vampir (ie I don't have to install vtf separately - right?)
And I can view with Vampir Trace the results of my app's parallel run? -----Original Message----- From: George Bosilca [mailto:bosi...@eecs.utk.edu] Sent: Thursday, April 10, 2008 8:31 AM To: Open MPI Users Cc: Swati Kher Subject: Re: [OMPI users] configuring with --enable-mpi-profile option 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. george.
