Here are the outputs from a series of runs. They include
1 and 2 processor tests for real*4 and real*8 data on
the C3200 series and C3400 series (total of 8 data results).
I could not get access to a fully configured C3800 to run this benchmark,
as the few we have are dedicated to paying customer benchmarks and final
product development. Next quarter I expect to have some impressive
results (clock speed diffs suggest a 2.4 times increase in speed).
As we have discussed before, these benchmarks don't properly represent
our compiler's ability to reuse vector data for many common loops such
as linpack and matrix multiply to obtain a MUL-ADD for each memory
reference. However, they do measure one important aspect of total
system performance.
I separated each set of results with a line of +++'s and a one line
description of the machine configuration which it ran on.
