Abstract

Vectorization reduces CPU time, whereas parallelization leads to a reduction of wall-clock time at the cost of more CPU cycles. Application programs will in general not be perfectly parallel. Therefore a static scheduling scheme for processor usage will lead to a waste of cycles. In contrast with this, dynamic allocation of processors will prevent CPUs from being idle as long as there is work to do.
