Re: [AMBER] Need help for PMEMD 10 installation

That's what we have seen on at least one comparison benchmark (from intel, I
believe, comparing their mpi implementation to several others on a large
cluster). I have never supported openmpi for pmemd because 1) when it first
came out, the release date was very close to an amber release and the
available documentation on openmpi was not very thorough, 2) later
indications were it is relatively slow. This may not remain the case
forever, but it has been true in the last couple of releases that there were
really no benefits associated with moving from the mpi implementations we do
support to openmpi.
