Parallel Processing using PVM
Although PVM rather quickly became a de facto standard, critics pointed out that in actuality there was no formal, enforced standard. It was also clear that the message passing was slower than optimized protocols native to an architecture. Very soon after the spread of PVM, a standard was put forward called MPI, the Message-Passing Interface. MPI has advantages (e.g., faster message passing, a standard) and disadvantages (e.g., not interoperable among heterogeneous architectures, not dynamically reconfigurable) with respect to PVM. PVMPI is a newer project which will combine the virtues of both approaches. The success of this project together with any standardization efforts of PVMPI may determine the future viability of PVM.
