[gmx-developers] thread_mpi for Power7 on Linux PPC64

[Sander Pronk]

I fixed that part of the library to work on ppc/power with xlc a while ago; what OS is this? Unfortunately, I don't have access to a Power/ppc machine right now, so unfortunately I can't reproduce it. 
One thing you might want to try is adding the compiler flag '-qasm=gcc'. Please let me know if that works.
