Parallel Virtual Machine (PVM) is software system that allows a homogenous (same type) or heterogeneous (different types) networks of computers to be used as a single computational resource . The individual computers may be interconnected by a variety of networks such as Ethernet or FDDI. PVM is used to build and manage the virtual parallel machine and provide the necessary message passing communication. By sending and receiving messages, multiple tasks can be used co-operatively to solve problems in parallel. Under PVM a network of workstations can be used as a single distributed memory computer. The individual machines may have shared or local. This can be used to solve problems which need high computational power
