Re: MPICH-GM 1.2.5..9.

Greg,

Yes there is a performance benefit in using mpich-gm with intel versus gcc.
mpich-gm compilations with the intel compiler are comparable to mpich-gm
compilations with the pgi compilers.  When testing hpl runs with the differently
compiled mpich-gm releases, the intel and pgi compiled versions gave better results
than the gcc compiled version.

Regards,
