dc.description.abstractPM-PVM is a portable implementation of PVM designed to work on SMP architectures supporting multithreading. PM-PVM portability is achieved through the implementation of the PVM functionality on top of a reduced set of parallel programming primitives. Within PM-PVM; PVM tasks are mapped onto threads and the message passing functions are implemented using shared memory. Three implementation appproaches of the PVM message passing functions have been adopted. In the first one, a single message copy in memory is shared by alI destination tasks. The second one replicates the message for every destination task but requires less synchronization. Finally, the third approach uses a combination of features from the two previous ones. Experimental results comparing the performance of PM-PVM and PVM applications running on a 4-processor Sparcstation 20 under Solaris 2.5 show that PM-PVM can produce execution times up to 54% smaller than PVM.pt_BR
