The
presentation describes two projects in the area of performance
evaluation. The first project, Parallelism Evaluation Methodology,
demonstrates the relationship of parallelism to performance,
and shows where various agents change the parallelism on
the path to performance. A simulation tool is described
which allows the study of executed parallelism within a
single CPU of a CRAY Y-MP. A methodology is presented and
applied to the measurement and comparison of executed parallelism
within several of the Perfect Benchmarks.
In
the second project, Benchmark Set Construction Methodology,
results are presented on the profile of usage, by populations
of academic users in different application areas, on the
CRAY Y-MP/464 at the National Center for Supercomputing
Applications. Hardware Performance Monitor data collected
over a period of one year is analyzed. The collected data
contains HPM group 0 performance information for approximately
300,000 jobs representing about 18,000 CPU-hours. This data
serves as a specification to be approximated by a benchmark
set which represents the workload at this site.
If
time allows, a short presentation will be given on the practice
of BenchMARKETing: The Art of Selling Inferior Goods.
