Biography

A staff member of the NRC Information Management Services Branch, Dr. Gabriel Mateescu works as a systems and applications analyst in the Research Computing Support Group. He is a partner with the NRC Institute for Information Technology High Performance Computing Group Grid Infrastructure project. Gabriel holds a Ph.D. in Computer Science from Virginia Tech, Blacksburg, VA, USA.

Gabriel has been responsible for the deployment and customization of middleware for cluster and grid computing. He has extended the Portable Batch System (PBS), a cluster scheduling system, to support a flexible scheduling strategy suitable for dynamic workloads. He has deployed Globus to several sites across Canada, from Fredericton NB, to Montreal, to Ottawa, and has built several extensions to Globus, from adding new information providers to parallel job submission tools. In addition, Gabriel has contributed to the construction of several Beowulf clusters and has designed and implemented new algorithms for load balancing and collective communication for parallel and distributed applications.

Before joining NRC, Gabriel worked at Platform Computing in Toronto, participating in the development of the Load Sharing Facility (LSF) distributed workload management system. Previously, he worked in scientific computing at Los Alamos National Laboratory and at Virginia Tech, developing parallel scalable software and algorithms for solving very large systems of linear equations and for fluid flow problems.
