In both cases, it seems to me to be a case of information overload. For someone running their first MPI program, there's so much there that it's a bit confusing. I've had about 20 years experience deciphering *nix man pages, and while all the info was there, it was difficult to find the relevant info. On a re-read, now that I know what I'm looking for, I was able to find the info in the man page. Perhaps an "EXAMPLES" section... I know that I wouldn't really have looked under "Location Nomenclature" for an example of how to run an MPI program. The mpirun -h, again, on re-reading, is clear. I guess part of my problem is the horrendous error message. Perhaps a reasonable default (such as C) might solve some issues. ------------------------------------------------------- This SF.Net email is sponsored by: New Crystal Reports XI.
