- A former student of mine and I did an extensive study of CM-2 execution
- time for basic operations. This work includes the relevant tests of
- the 76 tests done on the CM-1 by O'Farrell [OFA87] and an additional 42
- tests that we designed. These tests provide execution time information
- including the mean, minimum, maximum, and standard deviation, since
- timing on the CM-2 must be done through the front end and is subject to
- perturbation by other processes running on the front end host. The
- tests cover operations such as: integer add, subtract, multiply,
- divide; floating point add, subtract. multiply, and divide; inner
- product; image smoothing (3x3 kernel); and communications of many, many
- types.

- Our work is summarized in [MyA91]. The work was done in the summer of
- 1988 at the Research Institute for Advanced Computer Science at the
- NASA Ames Research Center. There is also a technical report [MyA88]
- that shows everything we did, including complete listings of the test
- codes and the performance measurement code.
-
- The technical report is available in hardcopy (113 pages) or postscript
- (0.56 MBytes).
