another minor question... Is there any way to force CPU affinity, or does
mprime do that automatically?
Unlike Windows, linux has a smart CPU/task allocation algorithm that tries
hard (but not too hard) to run a thread on the same CPU it used last. So
there's no need to force CPU affinity, in fact this might well damage
throughput.
As for hyperthreading - I believe the development kernel (2.5.x) has support
for hyperthreading. You will almost certainly need to build your own custom
kernel to obtain this support.
The best sources of information on task allocation on a multiprocessor linux
system are, not surprisingly, the kernel documentation and the source code
itself.
