pvm: PVM (Parallel Virtual Machine) pvm: pvm: PVM is a software system that enables a collection of heterogeneous pvm: computers to be used as a coherent and flexible concurrent pvm: computational resource. PVM support software executes on each machine pvm: in a user-configurable pool, and presents a unified, general, and pvm: powerful computational environment of concurrent applications. User pvm: programs written in C or Fortran are provided access to PVM through pvm: the use of calls to PVM library routines for functions such as process pvm: initiation, message transmission and reception, and synchronization pvm: via barriers or rendezvous.
