ABSTRACT
In this paper, we introduce the Join-Elect-Leave (JEL) model, a simple yet powerful model for tracking the resources participating in an application. This model is based on the concept of signaling, i.e., notifying the application when resources have Joined or Left the computation. In addition, the model includes Elections, which can be used to select resources with a special role. JEL supports several consistency models and is suitable for resource coordination of a wide variety of applications, ranging from the traditional fixed resource sets used in MPI, to flexible grid-oriented programming models.

JEL: unified resource tracking for parallel and distributed applications
When parallel applications are run in large-scale distributed environments, such as grids, peer-to-peer (P2P) systems, and clouds, the set of resources used can change dynamically as machines crash, reservations end, and new resources become available. ...
Adaptive resource allocation for embedded parallel applications
HIPC '96: Proceedings of the Third International Conference on High-Performance Computing (HiPC '96)Parallel and distributed computer architectures are increasingly being considered for application in a wide variety of computationally intensive embedded systems. Many such applications impose highly dynamic demands for resources (processors, memory, ...
