I would like to second the notion of converging on a single MPI interface. My parallel project encapsulates most of the inter- processor communication within higher-level objects because the lower- level communication patterns can usually be determined from higher- level data structures. But still, there are times when a user would like access to the lower-level MPI interface. I haven't tried to make my project compatible with any of the several MPI python interfaces out there, because it isn't clear to me which one is most widely used. If one were to emerge -- and even better, if the various independent projects were to then combine their efforts in an open source environment (the way Numeric and numarray are converging to NumPy) -- then this choice would be easy. ** Bill Spotz ** ** Sandia National Laboratories Voice: (505)845-0170 ** ** P.O.
