At this time, we are not using non-temporal stores for shared memory
operations.

Does the sm btl use a memcpy with non-temporal stores like MPI

Interestingly enough on the SPARC platform the Solaris memcpy's actually
use non-temporal stores for copies >= 64KB. By default some of the mca
parameters to the sm BTL stop at 32KB. I've done experimentations of
bumping the sm segment sizes to above 64K and seen incredible speedup on
our M90
