Areas of Interest Resource management in parallel and
distributed systems, system and application
performance, scientific computing
Summary of Research
Dr. Weissman's research interests center on runtime resource
management in parallel, distributed, and metasystem environments. He
has investigated topics in load balancing, granularity control for
parallel computations, and network-based job scheduling. He is
interested in building tools to support efficient, seamless, resource
management, and in applying the tools to real workloads including
parallel scientific applications. Some future topics of interest
include computational biology, mobile computing, and wide-area
Dr. Weissman received
a Nasa Graduate Research Fellowship from 1991-1995.
