Processes versus Processors


In ScaLAPACK, algorithms are presented in terms of processes, rather than physical processors. In general there may be several processes on a processor, in which case we assume that the runtime system handles the scheduling of processes. In the absence of such a runtime system, ScaLAPACK assumes one process per processor.
