The software from ftp://ftp.cs.wisc.edu/sohi/Code/simplescalar ?

Hm, can you explain that? 96% complexity reduction means what?
That 20 CPUs in parallel need only 4% of the time that 1 CPU needs?
That would be a speedup factor of 25, which I supposed is impossible
(well, at least very unlikely).
And how did you parallelization look like? Just ME? Or everything?
I'm really curious, because I did some experiments with parallel video
encoding a while ago myself. If you stuff is "private", maybe we can
discuss via private mail: gruel at gmx.de
