Hi all -
I'm trying to use jemalloc with my project, but I get a crash in
opal_memory_linux_ptmalloc2_open when jemalloc is linked. If I use
tcmalloc, this does not happen.
Any ideas? Is there a sanctioned way to override malloc libraries in
conjunction with openmpi?
Thanks,
Brian
Ralph and I talked some more about this.
Here's what we think:
1. The root cause of the issue is that you are assigning a non-existent IP
address to a name. I.e., maps to 127.0.1.1, but that IP address does not
exist anywhere. Hence, OMPI will never conclude that that is "local".
If you h
You can build Open MPI with --without-memory-manager -- that will turn off our
malloc hooks stuff.
But if you're using OpenFabrics, you'll get lower bandwidth for large messages.
