Re: Re: gtk+ and MPI

[Jim Parker <hopeye cfl rr com>]

Thank you for your help.  I'll play with it some once my test machine(s)
are back up.
Too bad the beowulf at work uses a queying system that does not allow
interactive programs.

BTW both my test and work machines use MPICH

cheers,
Jim Parker
