> Did anyone encounter this problem before? Any workarounds? Valgrind significantly increases the memory usage, and manages the address space itself (and differently from a native run). Which version of Valgrind are you using on which OS ? 32 or 64 bits ? I suggest to start valgrind with various tracing options to see what happens e.g. --trace-syscalls=yes -v -v -v -d -d -d and observe the traces around the mpich error msg Philippe ------------------------------------------------------------------------------ _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
