Add sha256q algo #174

Closed pyritepirate closed 5 years ago

JayDDee commented 5 years ago

I don't need to, the existing miner is as fast as it gets.

pyritepirate commented 5 years ago

It's different than sha256d and sha256t, but okay I'll close the PR.

JayDDee commented 5 years ago

I didn't mean I won't do it. I was just saying you already have the optimizations, essentially the same ones I did for sha256t, so I can't make it faster. I'll get to it eventually but I have a lot of other things going on.

I won't accept the pull but it can be used like an issue. I'll close it after the release that includes sha256q. I may make a couple of minor changes resulting from the work I'm currently doing.

JayDDee commented 5 years ago

I can add sha256q fairly quickly but I have nowhere to test, it's not on the major pools. If you can provide a place I can test it you have the shares I mine. Or I can just submit it untested. It's so close to sha256t it's hard to mess up. You can send the mining credentials by email if you wish.

ok, mining credentials below: -a sha256q -o stratum+tcp://us.coinminingpool.org:4800 -u PRk42ijnW5UAAAZUZyUjY4bJexX9xQ9YRM

Testing in progress, so far so good.

Everything is ok with testing. Thanks for your help. I have a few more things to do before it's released

JayDDee commented 5 years ago

v3.9.2 is released.If you have a Ryzen make sure you compile properly to use its SHA feature.

Let me know of any problems.

pyritepirate commented 5 years ago

Thanks for including it in the latest release.
