About me
Senior manager, Deep Computing Software and Applications
Research lab: Watson Research Center
I received the B.S. and M.S. degrees in electrical engineering from Oklahoma State University, and the Ph.D. degree in electrical engineering from the University of Illinois in 1990, where I was a student in the Center for Reliable and High-Performance Computing
Since 1990 I've been a Research Staff Member at IBM's Thomas J. Watson Research Center in Yorktown Heights, NY. Here at IBM Research I was one of the co-designers of the Vulcan parallel computer, and worked to transfer the Vulcan switching network into the High-Performance Switch of IBM's RS/6000 SP parallel system offerings. Since that time I contributed to three more generations of SP switching networks, including architecting and co-designing the Federation switching network used in the ASC Purple machine at Lawrence Livermore National Lab. The cluster offerings that use these networks are now known as Cluster 1600 systems.
I'm currently serving as Senior Manager of the Deep Computing Software and Applications department. In this role I lead several efforts within the high-performance computing (HPC) software space:
- Blue Gene software design
- Cell algorithms and applications
- Performance tools for HPC systems, including IBM's HPC Toolkit
- Visualization systems, including IBM's Deep Computing Visualization (DCV) system
I have served as an associate editor for IEEE Transactions on Parallel and Distributed Systems, co-chaired CANPC '97 and CANPC '98, the Workshops on Communication and Architectural Support for Network-based Parallel Computing, co-chaired CAC '01 - CAC '05 and CAC '07 - CAC '08, the Workshops on Communication Architecture for Clusters, and am serving as the Networks Area chair for the Supercomputing '07 and '08 program committees.
My research interests include parallel architectures, algorithms, applications, and performance analysis.
