All, Per George's recommendation, I found the following definition of ompi_fortran_integer_t
#define ompi_fortran_integer_t long long My application is working fine with the MPI_STATUS_IGNORE flag set Cheers, --Jim On Tue, Nov 12, 2013 at 3:42 AM, George Bosilca <bosi...@icl.utk.edu> wrote: > On Nov 12, 2013, at 00:38 , Jeff Squyres (jsquyres) <jsquy...@cisco.com> > wrote: > > > 2.
