I don't really know, I am not familiar with the linux scheduler. However
as far as I know there is no direct way to tell a process to execute on a
particular processor. The disadvantage of processes hopping from cpu to
cpu is that the cache does not hop with them. However perhaps linux is
already smart about this, I'm not sure.
