The original ptsminer, that is the one current implementation on github. I might ask compared against what else?

I'm currently working on an optimised ptsminer v0.5, I'm looking for people that might want to give it a try! The current version of the optimised version is some 30-35% faster depending on the cpu used (and what compile flags I give it), at the moment I'm only bothering with OSX and linux clients only.

So, anyone want to give this miner a test? drop me a PM if your interested.

I've tested thoroughly on Intel Core i7 based cpu's with good results. I'm not likely to push this much further, although that would definitely be possible with work.

All - well I wanted to post this to a different forum, but alas 'newbies' post here.

Anyway, I was asked by a friend with a bit of CPU power to optimise the sse2_64 core, a couple of hours later and I have a new core, sse2_64_atom. The development and the mainstay of the testing took place on an Intel Atom, so please forgive the name. However, it should give speed ups on many cpu's, particularly Intel as you all know 4way is still fastest on AMD (although this significantly decreases the gap).

An example on an Intel Atom D525 (dual core),

[2011-06-14 14:18:42] 2 miner threads started, using SHA256 'sse2_64' algorithm.

[2011-06-14 14:18:19] 2 miner threads started, using SHA256 'sse2_64_atom' algorithm.
[2011-06-14 14:18:31] thread 0: 16777216 hashes, 1234.20 khash/sec

That is about +18% and counting.

Benchmarks are much appreciated! although comments/flames are also welcome.
