Comment (by knarf):

 I don't care which mpi version is used, as long as it works. I just
 commented here because nobody else reported either failure nor success
 with mvapich2, and I didn't see these problems so far. Maybe the
 differences between the git and hg version are large enough to not be a
 problem here, whether that problem might be in Carpet or mvapich2. I
 actually have something running now using the git version (not because of
 this ticket) and it might be interesting to see if I can checkpoint this.
 Also, I believe Roland is using the Curie-ET on lonestar and I know that
 he could checkpoint without problems using the git version as well. So,
 while I am not per se against changing the MPI version, I also see some
 people who do not have any problem with the current setup. It would be
 interesting to know why, although it might be hard to find out, I agree.
 How many people tried OpenMPI on lonestar, and was there a speed-penalty?
