[comp.sys.apollo] Benchmarks for DN10000?

sullivan@msor.exeter.ac.uk (Rob Sullivan) (07/13/89)

My department (theoretical solid state physics) is interested in buying a new
machine in the near future. It would be very useful if someone could provide a
reliable set of benchmarks for the DN10000, which we would expect to use as a
three processor system. Benchmarks for the Stellar DS2500 and DS2000 would also
be extremely valuable.

                                     Thanks in advance,

I don't know how reliable these benchmarks are but here are some
results obtained with a single cpu loaner from the local office.
Not sure how much memory it had, but swapping was not a factor.
Time was measured using /bin/time, except the graphics benchmark.

The results are in seconds.  The numerical integration involves
single and double precision floating point for the most part.
The FFT's are single precision.  The beam pattern involves
a 2 dimensional FFT and false color intensity plot, about 5000
trapezoids.  This was a single processor machine with the 
extra graphics hardware.  The pascal compiler was used which
according to the salesman is already one revision behind.

First there is no such animal as a "reliable set of benchmarks".  But to
answer your question, we have seen from 4 to 15 times faster wall clock
times than a DN4000.  Our DN10k is a multi-processor, four CPUs.
When running three jobs in parallel each job ran less than 10% longer
on wall clock time.  Note all programs and all data resided in the single
DN10K's disk.

Your real question should be what will be the easiest machine to use in
our Apollo environment.  The answer hands down is a DN10K.  For us, it
was a plug and play, and on the ring in a couple of days (due to newness
of SR10).
