This paper presents CPVM, a library that provides the user with a support to implement non blocking, blobal checkpoint- restart algorithms for applications written using PVM thereby achieving fault-tolerance. A salient feature of CPVM is the way in which, solely on the basis of a simple set of new PVM primitives, it provides several advanced facilities useful to solve different problems. CPVM can also be used as a platform on top of which to implement different algorithms to detect stable properties such as deadlocks and termination, and to support job-swapping and migration in an environment where there previously was none.

Abstract
This paper presents CPVM, a library that provides the user with a support to implement non blocking, blobal checkpoint- restart algorithms for applications written using PVM thereby achieving fault-tolerance. A salient feature of CPVM is the way in which, solely on the basis of a simple set of new PVM primitives, it provides several advanced facilities useful to solve different problems. CPVM can also be used as a platform on top of which to implement different algorithms to detect stable properties such as deadlocks and termination, and to support job-swapping and migration in an environment where there previously was none.
