There is great potential if one could effectively harness the computation power of the plethora of low priced powerful yet under-utilized workstations connected by high-speed networks. In recent years, rapid improvement of advanced hardware and progress in networking technology is also making PC clusters a competitive platform for parallel computing. Traditionally, cluster programming has been performed with message passing libraries. As the performance, especially the latency, of the communication network improves, the expectation to support a shared memory programming model on clusters is reviving. In this paper, we put forward a system having both a distributed shared memory cluster and heterogeneous computers as system nodes which can support automatic distribution, migration, communication and coordination of multithreaded applications on a heterogeneous platform. This will be a creative application-driven experimental infrastructure that will explore challenging problems in distribution management and control, in middleware integration and deployment, in software architecture and software engineering.
