I am forwarding some queries of mine on MPI to this list in hopes of getting some help.

As I mentioned earlier, MPI is clearly available (have used it in several other projects but not yet einsteintoolkit).  The option list file I have used makes explicit mention of various env variables which indicate where to care and feed the system&#39;s mpi.  Please help.<div>

<div><br></div><div>One would think that MPI would be wanted by default on any computing environment that one would want to do real computation on, with the exception of one&#39;s laptop or desktop I guess.</div><div><br>
