SPEC CPU2000 Benchmark Description File
Benchmark Name
171.swim
Benchmark Author
Paul N. Swarztrauber
Benchmark Program General Category
Meteorology: Shallow Water Modeling
Benchmark Description
Benchmark weather prediction program for comparing the performance of
current supercomputers. The model is based on the paper, "The
Dynamics of Finite-Difference Models of the Shallow-Water
Equations", by Robert Sadourny, J. ATM. SCIENCES, VOL 32, NO 4,
APRIL 1975.
Adapted by SPEC for use in the SPEC CPU Suites as an example of a compute
intensive floating point program that was once relegated only to
"supercomputers" but can now be done on current computer systems.
Input Description
It does a 1335x1335 area array of data and iterates over 512 timesteps.
Output Description
It prints the diagonal elements of the velocity field.
Programming Language
Fortran 77
Known portability issues
None.
