Hi,
	Are MPICH2 calls optimized for SMP/multi-core architectures if I 
allocate buffers using MPI_Alloc_mem()? I was reading the in the MPI2.1 
spec that MPI_Alloc_mem can be implemented to take advantage of shared 
memory pools when available meaning I can keep my code portable and 
clean. Presumably this would only be available in ch3:ssm and nemesis 
channels.

Regards
James
