[gmx-developers] thread_mpi for Power7 on Linux PPC64

[Brad Lambeth]

That compiler flag didn't work, I think the compiler actually defaults
to -qasm=gcc now.  The OS is Red Hat Enterprise Linux 5.4 with the
2.6.32 kernel.  The compiler versions are 11.1 for xlc and 13.1 for
xlf.  It appears to be something syntax related in
include/thread_mpi/atomic/xlc_ppc.h, but I can't figure out how to fix
it.  I can provide any other information you need, including the full
config.log.
