I did a hand-optimized version of the albert code. (windows, no SSE)
It produces absolutely correct results, but at least two times faster.
Can I use it without any kickback?
I do not work here or anything, but speaking in general, I think it would be best to submit your changes to the E@H staff, so 1. they can validate your claims, and 2. they can possibly use those changes in their main albert client
Having a 2x improvement in windows would be a huge help if the results are really just as accurate.
such things just should not be writ so please destroy this if you wish to live 'tis better in ignorance to dwell than to go screaming into the abyss worse than hell
Who's to say he did. Hand optimizing asm isn't much less difficult than running a disassembler on an executable to get (undocumented) asm out. Farthermore, running the app under a debugger would allow you to profile the execution and determine where the code was spending most of it's time, and thus where to concentrate the optimzation.

I'm very interested in this. I'll send you an email off list.
Any results on this so far? Any beta-testers needed? :)
I would like to help on speed optimization, but i don't know what is the way of it. Probably i can put my code on a webpage, but i think it would be not legal. I didn't get any e-mails in connection with legitimacy.

Are you currently using your modified binaries? Because wow, 345.38 RAC is pretty good for an athlon 1700

I second that one: a 2x

I second that one: a 2x speed-up would be huge. May I ask how you got the source code?

Try emailing Bruce directly. You can find his email at the bottom of his personal page. http://www.lsc-group.phys.uwm.edu/~ballen/

I seems so. He's crunching 1.5 times faster than my 2.5GHz X2 (for one WU)! That's damn impressive, even if the 1700+ may be OC'ed :)
