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.
