divides the processing loads
across several CPU
s. Two processors are not twice as fast as one because the main CPU controls the scheduling
and resource assignment
s. Windows NT
with two processors is theoretically
150% faster than one processor, but I've seen an average of 167% increase on my home server
There are two types of multiprocessing:
Symmetric shares the total processing load among all available processors as equally as possible.
Asymmetric dedicates certain program threads to particular processors.
