[mvapich-discuss] Unable to compile IBM test suite

[Jonathan Perkins]

This doesn't appear to be an mpi issue.  The code that is failing is
using the mmap
system call but MAP_ANONYMOUS is not available for some reason.

Excerpt from mmap man page:
      Of  the above flags, only MAP_FIXED is specified in POSIX.1-2001.  How-
      ever,  most  systems  also  support  MAP_ANONYMOUS  (or   its   synonym
      MAP_ANON).

Maybe your system isn't like most?  You should try compiling a simple c
program using mmap with MAP_ANONYMOUS and whatever compiler mpicc is
using.  If it fails the problem is there, otherwise we can investigate
further.
