Just to strengthen this answer: here's a snipit from one of the
questions on the FAQ:
"Note that LAM has no concept of scheduling on CPUs -- this is the
responsibility of the operating system. The "C" notation is simply
convenitent representation of how many jobs should be launched on each
node. LAM will launch that many jobs and let the operating system
handle all scheduling/CPU issues. So the prior example would not
necessarily have manager and the first worker competing over the first
CPU (assuming that c0 is located on an SMP); it means that LAM would
schedule (M+1) programs on a machine with (M) processors."
