Re: MPICH-GM 1.2.5..9.

Patrick,

In trying to keep things as simple as possible we used:
	mpicc
which called icc, that linked to the mpich library compiled with the intel compilers.

And the same for gcc,
	mpicc -> gcc -lmpich (compiled with gcc)
And the same for pgi,
	mpicc -> pgcc -lmpich (compiled with pgi suite)

I haven't tried a hybrid or can't remember trying it :-) 
	mpicc -> icc -lmpich (compiled with gcc)

I can try it ... or rather put it on the list to try ...

Regards,
