[mvapich-discuss] MVAPICH2 with TCMALLOC

[Jonathan Perkins]

Hello Hector.  I believe that you're hitting an issue with tcmalloc
overriding an internal version of ptmalloc2 in MVAPICH2.  Can you try
disabling registration cache by specifying the --disable-registration-cache
option when building MVAPICH2?  Please let us know if this works out for
you.
