I was playing with the reaper code, mostly just pulling it apart to get an idea of how it worked, and I thought it would be useful to hack it up to run through a range of scrypt GPU settings and measure the performance so I don't have to slog through it manually. It seems like the "stab in the dark" settings I was previously using for my NVIDIA cards were way off base, because I've easily picked up another 50% hash rate by using settings found with my hacked miner.
If anybody else wants to try it out, I can post the (still extremely ugly) source and some Windows binaries on Github this weekend. Right now I've only run this on NVIDIA cards, but I'll pop an ATI card in my machine and make sure that works before I post it. I'm not sure I'll get around to making sure Linux works before I post, but I can do that later on this week.
I don't plan on spending a lot of time polishing this thing, as I'd still prefer to work on things that would be more useful for making LTC adoption easier (assuming I can learn the things I need in order to do that effectively), but I did want to throw this out there if it seems like it would save people some time.
CGMINER.
See if you can help there.
Reaper is useful for those who can't get cgminer to work right.
