I disagree. I've been examining the gcc benchmark of the SPEC suite for
perhaps a month, now, and it is a /very/ scalar benchmark. Although I may
not at this time release a SPECratio (lest it be set in stone), I can
say that the majority of the 10 SPEC benchmarks smile favorably on the
Convex C-series computers, especially when you consider the price of the
computer. A couple of them might blow your formidable mind (regardless of
price), but you'll have to wait until we're ready to unveil them. As of yet,
I have only run the gcc SPEC benchmark using a scalar compiler built for
portability, not optimization for speed, so I can't give you a good feel for
the speed. However, the profile does indicate that it will be a very
scalar benchmark.
I can't give you a date when we'll be releasing the numbers, but we seem to
be very close. I've made trial runs of the SPECthruput as well. The C-series
once again performed very well. I'll keep you posted of the release date for
the actual numbers.
I am also a fan of the SPEC benchmarks. I think they're a really good
indication of performance. However, inevitably, the best measure of a
machine's speed is to see how fast a customer's application will run on it
with a customer's typical load. Convex's do what they were designed to do
/extremely/ well. Vectorization and parallelization are very important
factors for most of our customers. Therefore, our customers are usually very
happy with the product. We have the /best/ machines in our price bracket for
semi-vectorizable/parallelizable jobs.
