Comment (by hinder):

 The optionlist has been committed.  I would like to change the default
 optionlist for LoneStar to lonestar-openmpi.cfg for the ET release.  Two
 people (Frank and I) have now seen problems with MVAPICH and no one has
 reported a problem with OpenMPI.  The only problem at the moment is that
 we were doing production simulations and hence were using the stable
 version of Carpet, which means that the development version has not been
 tested with OpenMPI on LoneStar.  I would be surprised if this led to
 problems, given that OpenMPI is used on many other machines without
 problems.  In the time before the release, I can't do extensive testing,
 so I propose that I run a test BBH simulation on LoneStar and if that
 works with OpenMPI, then I will commit the OpenMPI parameter file.  I
 think this is better than releasing with MVAPICH which we have seen to
 have problems.
