Checkpointing protocols usually rely on the constitution of consistent global states, from which the application can restart upon a failure. This paper proposes a new characterization and technique to build a recoverable state, aiming at relaxing the constraints and overhead. , for Promised consistency, is proposed as such a recovery condition...

This research report first details a communication induced checkpointing fault tolerance protocol adapted to ProActive, a Java library that implements the ASP model. This model is based n a request/reply mechanism. In order to prove the correctness of this protocol, we introduce a local partial order between events occurring on a given process....

We propose in this paper, a mechanism for Grid computing frameworks, for specifying environmental requirements that may set and be optimized by deployers. Specified by designers by parameterizing deployment abstractions, the constraints can be dynamically mapped onto the infrastructure. This work is integrated in the ProActive middleware with...

This paper reports on the design, implementation and benchmarking of a Java version of the Nas Parallel Benchmarks. We first briefly describe the implementation and the performance pitfalls. We then compare the overall performance of the Fortran MPI (PGI) version with a Java implementation using the ProActive middleware for distribution. All...

Since the appearance of distributed computing technology, there has been a significant effort in designing and building the infrastructure needed to tackle the challenges raised by complex scientific applications that require massive computational resources. This increases the awareness to harness the power and flexibility of Clouds that have...
