What about Multicore?
Heroux / Edwards / Doerfler
Chip multi-processors (CMPs) offer a new challenge and opportunity for
application developers. Although using MPI to access all cores is possible
in principle, it is very likely that MPI-only will not be sufficient. At
the same time, no one knows what other approaches will be best, or when and
how. Characterizing the effective use of CMPs is essential at all levels
of computing. At the low end, exploiting increasing core counts is the
only way to see performance improvement from hardware. At the high end,
all paths to petascale (and exascale) performance require effective use of
large-core-count CMPs in some form.
