[Valgrind-users] valgrind and MPI wrappers

[Andrew T B. <And...@Co...>]

I'm trying to use Valgrind to debug an MPI program.  The user manual gives some instructions (section 2.16) and I follow them, and it says that if things are working I should get notices like this when I run my program:

valgrind MPI wrappers 31901: Active for pid 31901
valgrind MPI wrappers 31901: Try MPIWRAP_DEBUG=help for possible options

I do not get such notices, and Valgrind seems to be giving me lots of false positives from the MPI libraries.  The configure script for Valgrind reports that it finds a usable mpicc.

What am I missing?  Thanks for any help.
