The Tool-set Project: Towards an Integrated Tool Environment for Parallel Programming

Writing parallel programs eeciently is still a problematic issue due to the lack of a uniform and integrated tool support. A new project at LRR-TUM works towards changing this situation for the most popular programming environment on workstation clusters: for PVM. The Tool-set for PVM will comprise a set of integrated tools, consisting of a debugger, a performance analyzer, a visualizer, a deterministic execution controller, a load balancer including a checkpoint generator, and a parallel le system. In contrast to previous work, these tools are compatible to each other by using a common monitoring system, thus avoiding special preparation of a parallel program for each single tool. In addition they can be used together to observe and control diierent aspects of a single program run.
