What do you mean by "I believe that a new release is imminent"? do you know is inminent, or you HOPE it is? I do not have any reference about this future implementation but, if you do have any idea about when will it be available, I'd thank you very much if you told the newsgroup. Another question around this: Is there any risk for MPI to left the world of free implementations, relying only on commercial versions? (there are already some commercial MPI-2 implementations avaliable now, far before the "hypotetical" free versions). Did MPI-1 public versions suffered from the same delay with respect to commercial? Thanks all for your answers.
