Do you want to use MPI to chain a bunch of such laptops together (e.g. via
ethernet) or just for the cores to talk to each other? If the latter; you do
not need MPI. Your SMP operating system (e.g. Linux) will automatically
utilize both cores. The Linux 2.6 kernel also supports processor affinity
which will always schedule the kernel on a fixed core, avoiding cache
invalidation and stuff like that.

Thanks

Durga
