Subject: IBM 1990 Supercomputing Competition


"Call for Papers" to be presented at the
IBM Large Scale Computer Analysis and Modeling Conference
Park City, Utah April 24 - 26, 1991

Sponsored by the IBM Corporation and IBM Canada Ltd.

IBM invites authors from industry, research and academia to submit
papers in competition for major cash awards. The competition is for
First, Second and Third Prizes in each of five divisions:

Physical Sciences and Mathematics
Life and Health Sciences
Social Sciences, Humanities and the Arts
Computer Sciences - Distributed and Cooperative Processing

The prizes in each of the five divisions are:

1st - $25,000, 2nd - $15,000, and 3rd - $10,000

Each paper must describe large scale analysis and modeling work
using an IBM 3090 with Vector Facility as the primary computational
system or the paper must describe new and innovative approaches to
analysis and modeling using distributed or cooperative processing in
which IBM technical workstations are linked to IBM mainframes.
Judging will be done by panels of noted non-IBM experts in each
division. IBM will join in publishing the winning and honorable
mention papers selected by the panels of judges. The PROCEEDINGS
will include all prize and honorable mention papers and abstracts of
selected additional papers. To enter the competition, authors must
submit an acceptable abstract and complete the registration
procedures. All necessary information is provided in the General
Information Brochure which can be obtained from your local IBM
Branch Office or by contacting:

FAX: (203) 792-7507 (416) 758-4136

Registrations must be received by October 16, 1990. Final papers
must be received by January 15, 1991. Papers will be presented at
the IBM Large Scale Analysis and Modeling Conference, Park City,
Utah, in April 1991.

The competition is open to any individual or team working or living
in the U.S.A. or Canada, excluding employees of the IBM Corporation,
IBM Canada Ltd., and IBM related companies and their families.
