Many-core chips that look like a big x86 SMP don't look anything like
a GPU. With the addition of a few commuications primitives, MPI
will run even better on big x86 SMPs. All of the programming
approaches for GPUs and Clearspeed and historical array processors
are yucky compared to "high level language + MPI".
