i noticed your stream results don't include any measurements for
non-supercache SS10 systems, so i went ahead and compiled things up on
one of our SS10/30s and ran some measurements.
the specific details are:
- SS10/30 (36 MHz, 20/16 kbyte on-chip I/D caches)
- SunOS 4.1.3
- compiled with "f77 -O4 -Bstatic" (using whatever version of f77 we
got from sun at the same time they shipped us sun C 1.0; it's almost
cetainly not the latest and greatest FORTRAN compiler from sun)
