The slalom benchmarks were developed at NASA Ames Laboratory, and are described in
John Gustafson, Diane Rover, Stephen Elbert, and Michael Carter
SLALOM --- The First Scalable Supercomputer Benchmark
Supercomputing Review 3(11), 56--61, November 1990.
John Gustafson, Diane Rover, Stephen Elbert, and Michael Carter
The design of a scalable, fixed-time computer benchmark
Journal of Parallel and Distributed Computing 12(4), 388--401, August 1991.
The benchmark code does not appear to be available at the developer's Web site, http://www.scl.ameslab.gov/, but a copy can be provided from this site on request; send electronic mail to beebe@math.utah.edu
