A user-level process package for PVM

Abstract

This paper describes an approach to supporting efficient processor virtualization and dynamic load balancing for message-based, parallel programs. Specifically, a user-level process package (UPVM) for SPMD-style PVM applications is presented. UPVM supports light-weight virtual processors that are transparently and independently migratable. It also implements a source-code compatible PVM interface, which means that existing PVM programs only need to be recompiled and re-linked. The performance of UPVM is discussed and compared with that of standard PVM.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
