Paul Messina

ORG Argonne National Laboratory, CERN, and University of Southern California Title Distinguished Senior Computer Scientist BIO Paul Messina is Distinguished Senior Computer Scientist at Argonne National Lab, visiting professor at CERN, and visiting research scholar at the Information Sciences Institute of the University of Southern California. From 1987 to 2002 he was at the California Institute of Technology (Caltech), where he held the positions of Faculty Associate in Scientific Computing, Assistant Vice President for Scientific Computing, and Director of Caltech''s Center for Advanced Computing Research. In 2002, he was named to the NSF Blue Ribbon Panel on Cyberinfrastructure. During a leave from Caltech from January 1999 to December 2000, he was Director of the Office of Advanced Simulation and Computing for Defense Programs in the National Nuclear Security Administration, Department of Energy. In that capacity he had responsibility for managing the Accelerated Strategic Computing Initiative, the world''s largest scientific computing program, which is defining the state of the art in that field. He holds the position of Chief Architect for the National Partnership for Advanced Computational Infrastructure (NPACI), a partnership established by the National Science Foundation and led by the University of California, San Diego. His recent interests focus on advanced computer architectures, especially their application to large-scale computations in science and engineering.

He has also been active in high-speed networks, computer performance evaluation, and Petaflops computing issues. Prior to his assignment in DOE, he led the Computational and Computer Science component of Caltech''s research project funded by the Academic Strategic Alliances Program (ASAP) of the Accelerated Strategic Computing Initiative (ASCI). In the mid 1990s he established and led the Scalable I/O Initiative (SIO), a large scale-effort to address input/output scalability issues in large-scale computing; the SIO had over 15 participating institutions. In the early 1990s he was the Principal Investigator and project manager of the CASA gigabit network testbed. During that period he also conceived, formed, and led the Consortium for Concurrent Supercomputing, whose thirteen members included several Federal agencies, National Laboratories, universities, and industry. That Consortium created and operated the Intel Touchstone Delta System, which was the world''s most powerful scientific computer for two years. He also held a joint appointment at the Jet Propulsion Laboratory as manager of High-Performance Computing and Communications from 1988 to 1998.

Messina is associate editor of the journal Concurrency: Practice and Experience and on the editorial Board of the IEEE Journal Computing in Science and Engineering. He has been keynote speaker at a number of international conferences, including the 1999 International Meshing Roundtable, the 1997 SIAM Annual Meeting, the 1997 Mannheim Symposium, the 1996 ICPP Workshop on Challenges for Parallel Processing, HPCN Europe ''95, Supercomputing Japan ''92, the 1993 High Performance Distributed Computing 2 Conference in Spokane, WA, and the 1991 IMA Conference on Parallel Computation, Oxford, England. Paul will continue at Caltech on a part-time basis for the near term to facilitate the Institute''s participation in the Teragrid project during its formative first year. He will also assume part-time senior advisor positions at CERN and Argonne National Laboratory.
