Home > Parallel Virtual Machine


The Parallel Virtual Machine (PVM) is a software tool for parallel networking of computers. It is designed to allow a network of heterogeneous machines to be used as a single distributed parallel processor.

PVM was developed by the University of Tennessee, The Oak Ridge National Laboratory and Emory University. The first version was written at ORNL in 1989, and after being rewritten by University of Tennessee, version 2 was released in March 1991. Version 3 was released in March 1993, and supported fault tolerance and better portability.

Though PVM is not being actively developed, it was a significant step towards modern trends in distributed processing and grid computing.
