I believe the issue deals partially with the interoperability of the FORTRAN function call interface. (meaning: case, underscores, and implicit string length argument placement) Do ifc/efc and g77 use the same conventions? I don't know if cc=gcc and fc=ifc works when compiling mpich.

If there's no proven performance advantage to compiling the Myrinet stuff with the Intel compiler, then why should Myricom work around bugs in the Intel compiler? greg _______________________________________________ Myrinet mailing list [email protected] http://email.osc.edu/mailman/listinfo/myrinet
