The SPEC benchmarks (sources) have been officially released, and about
a dozen machines' results (their "SPECmark" ratings) have been published;
see, for example, EETimes Oct 9, page 1.
One of the machines that did quite well* was the Apollo DN10000, which has,
among other things, multiple instruction issue (superscalar) and a
"FP multiply and add" instruction. {was this the inspiration for the
i860 which appeared 2 years later? :-)}
So this makes me wonder, how will a Serious multiple-instruction-issue
machine like a VLIW perform on SPECmarks? Does anybody out there have
SPEC measurements on a Multiflow computer, preferably one of the big
bohunker maxi-config models with lots of parallel execution units?
Measured *data* preferred (vs. conjecture/opinion).
Thanks in advance.
* one or two plain-vanilla scalar
machines SPECmarked about as fast
or slightly faster than the DN10000
