[gmx-developers] thread_mpi for Power7 on Linux PPC64

[Brad Lambeth]

When configuring the git master branch on our Power7 system, the
configure script warns that our cpu+compiler combination does not
support atomics and suggests disabling threads in favor of MPI.
include/thread_mpi.h seems to suggest that our cpu+compiler
combination should be supported (xlc on PPC64).  The relevant portion
of config.log is included below.
