I think it is exactly that.  Well, not so much "poor coding" as just coding
aimed at the machines most likely to run the program.

I ran Distributed Folding (Blueprint.org/U. of Toronto) on my 4xR10K
Challenge L, and did very well.  I started late, but when the experiment
closed, I was still gaining ground on the leaders.

Since I can't find anything better to do now, I'm running the Golumb Ruler
thing from distributed.net, and performance is very, very poor.

Given the realities of the installed base available to run distributed.net,
I'd be astounded if the code were not optimized for Intel processors, with
everything else relegated to the "if it runs at all, swell" classification.

If anyone knows of a medical-research distributed computing project that
runs well on IRIX/MIPS, please let me know.
