Subject: Re: [OMPI users] Using mtrace with openmpi segfaults
From: Jeffrey M Ceason (ceason_at_[hidden])

Is there a way to disable this at runtime? Also can an user app use
mallopt options without interfering with the memory managers?

We have these options set but are getting memory corruption that moves
around realloc in the program.

 mallopt(M_MMAP_MAX, 0);
 mallopt(M_TRIM_THRESHOLD, -1);

Re: [OMPI users] Using mtrace with openmpi segfaults

I have not tried to use mtrace myself. But I can see how it would be
problematic with OMPI's internal use of ptmalloc2. If you are not
using InfiniBand or Myrinet over GM, you don't need OMPI to have an
internal copy of ptmalloc2. You can disable OMPI's ptmalloc2 by
configuring with:

   ./configure --without-memory-manager
