  1. Does not work on 32-bit (though that’s not a problem with the algorithm).
  2. Patch is against older SVN. There’s a git repo at http://github.com/tcatm/bitcoin-cruncher
  3. Compiles on every 64bit Linux.

It’s not intended as a replacement for a standard client but for a dedicated bitcoinminer box. I’m planning a pluggable bitcoinminer someday. But at current difficulty it’s easier to work for bitcoins than finding faster ways for mining.

  1. Do we know why it doesn’t work on 32bit? Is is it because it’s using 128bits and if so, would it help if we dropped it to 64?

  2. Thank you, I will look into implementing it on my 64bit systems.

  3. Excellent to hear. I’m looking forward to using it.

I was planning on using it on a PE2650 dual proc Xeon @3.2GHz w/HT. I would really like to get this figured out to utilize that system. I am planning one as well. At current difficulty I would agree, except when the system needs to be run anyway and latency isn’t an issue.
