Arctic Region Scientists Slated for April Parallel Computing Conference

COLUMBUS, Ohio -- The conference " Parallel Computing: The T3D and Beyond " is scheduled for April 2-3, 1997, in Columbus, Ohio. Computational scientists from across the country are encouraged to attend and submit papers on parallel processing topics. The conference, co-sponsored by the Arctic Region Supercomputing Center (ARSC), the Ohio Supercomputer Center (OSC), and the Pittsburgh Supercomputing Center (PSC), will feature sessions on code development for applications such as atomic physics calculation, DNS-based fluid flow simulation, and adaptive finite element methods.

Other sessions include selecting the best parallel architectures for the particular science, learning how the Department of Defense is promoting parallel processing, and a forum for exploring the future direction of parallel processing. Don Morton from the Department of Mathematical Sciences at Cameron University in Oklahoma states that "the benefits of the CRAY T3D communications system are demonstrated in my recent timing data between a cluster of Pentium workstations and the CRAY T3D system." Morton, who uses the Cray Research systems at ARSC , said his adaptive finite element code was recently packaged into a single executable, allowing for SPMD implementation on the CRAY T3D/E systems for increased portability and enhanced performance.

According to ARSC's Massively Parallel Processing (MPP) Specialist Guy Robinson , "The continued advancement of parallel systems, both in terms of faster hardware and developments in the supporting software tools, present new opportunities for Arctic researchers." Robinson will present an overview of some work recently started on a code which models three-dimensional seismic wavefields using a newly developed pseudospectral technique. This code will be used to simulate the impact of earthquakes in the Alaska Range and surrounding area. Such a large and detailed model requires parallel supercomputers and high performance visualization, both in setting up the modelŐs parameters and in the simulation of possible events for study.

University of Alaska Fairbanks Geophysical Institute software engineer Thomas Logan will talk about Parallel Processing and Synthetic Aperture Radar Imagery. Advances in supercomputer hardware and software combined with Logan's program development have reduced the time from two days to ten minutes to combine many satellite images of Alaska into one 'mosaic' image.

The conference will be at the Ramada University Hotel near The Ohio State University campus. For more information, see the conference web page: http://www.osc.edu/pcomputing/ or contact conference organizer, Stephen I. Gordon, (614) 292-4132, sgordon@osc.edu .

Partial funding for the conference is provided by the National Science Foundation (NSF) through the Metacenter Regional Alliance Program. The three sponsoring centers are a part of PhAROh , a NSF Metacenter Regional Alliance. This is an alliance between centers with similar and compatible computational facilities and operational philosophies. All of the centers have CRAY T3D or T3E systems and share documentation and information resources through e-mail and WWW applications.

By pooling resources, the PhAROh MRA centers effectively share developing expertise and understanding of the CRAY T3D and T3E environments, share code porting strategies and performance analysis tools, and co-develop outreach training and remote user service programs.

In operation since 1992, ARSC continues to support computational research, science, and engineering--with emphasis on the high latitudes and the Arctic. ARSC provides scalar-vector and massively parallel processing (MPP) talent and related resources--high-performance computing, networking facilities, training, and technical support--to federal and state agencies, the academic community, and commercial affiliates.
