LAM, MPICH, something else? I've used Lahey with LAM with no problem. MPICH is a little harder because of their use of command line arguments to spawn the processes, and I have had to monkey with the configuration parameters to build a library I can link from several Fortran 90 compilers, but it can be done. Also, are you sure you're linking in all the necessary MPI libraries? I suspect that Nils's suggestion that checking that the name manglings agree will solve the problem. IIRC, by default Lahey appends an underscore, but if the MPI libraries were built for g77 (usually the default) then procedure names that contain an underscore (i.e. all MPI routines which begin with mpi_) will have two underscores appended. When I build an MPI library I always look for a configuration parameter to keep it at a single underscore. -- William F.
