Abstract

Version 3.4.3 of PVM had previously been enhanced by the addition of a new architecture, BEOLIN, which allowed a PVM user to abstract a Beowulf class computer with a private network to appear as a single system, visible to the outside world, which could spawn tasks on different internal nodes. This new enhancement to PVM handles the case where each node on the Beowulf system may be composed of multiple processors. In this case, the software will, at the user’s request, spawn multiple jobs to each node, to be run on the individual processors.
