Optimizing Heterogeneous Task Migration in the Gardens Virtual Cluster Computer

The 9th Heterogeneous Computing Workshop (HCW 2000) is a forum to discuss latest ndings in heterogeneous computing and promising work in progress. Heterogeneous computing systems range from diverse elements within a single computer to coordinated, geographically distributed machines with di erent architectures. A heterogeneous computing system provides a variety of capabilities that can be orchestrated to execute multiple tasks with varied computational requirements. Applications in these environments achieve performance by exploiting the a nity of di erent tasks to di erent computational platforms or paradigms, while considering the overhead of inter-task communication and the coordination of distinct data sources and administrative domains. Such computing systems support information infrastructure and other terms including Cluster Computing and Grid Computing are also used to describe heterogeneous computing. HCW 2000 is co-sponsored by the IEEE Computer Society, through the technical committee of Parallel Processing, and the U. S. O ce of Naval Research. 42 submissions were received of which 32 papers were selected for presentation. The papers are grouped into 10 sessions along two parallel tracks. The following is the technical program.
