What kind of speeds does GG give for XMR with RX 470/480?

I am almost done. 11 out of 12 Equihash kernels work flawlessly.
GCN support of LLVM is incredibly buggy, but I can at least fix them now!

Are you seeing any speeds ups from using LLVM vs stock compiler?

Not yet, not yet. I'm still ironing out compatibility issues with the last kernel.

Pretty much the same as Claymore for me, but download it and try it out

Alright, all the Equihash kernels are working without problems with the new compiler now!
The speed is so-so, but it's a pretty good starting point.
Now I have all the goodies like inline assembly and compiler hints, he he he..

One word of caution: There seems to be a really nasty bug introduced in the LLVM 4.0 branch that involves either loop optimization or dead code elimination for GCN. Just to let you guys know.

Also, I would recommend the "amd-common" branch of LLVM 5 at ROCm's repository as this seems to have the most recent updates:

https://github.com/RadeonOpenCompute/llvm

GG's Equihash kernels are now running at 202 sol/s on stock RX 480 without parallel writes and GDS.
I can optimize parallel writes and GDS access with inline assembly, so it is getting pretty interesting.

Inline assembly is working as expected. So much better than writing the whole thing in assembly!
I will save the fun for tomorrow.

Hey zawawa, can you possibly mod you zcash implementation to work with new N & K Values like in this coin:

https://bitcointalk.org/index.php?topic=1796036.0

It's 192,7 instead of 200,9.

I've already modded tromp's solver to work with it but it's, of course, hell slow:

Hi Ocminer, is normal equihash solver working with it..like EWBF or nhqminer?

Well Yeah I was reading through the spec change of the parameter. Well I have asked EWBF if he could add Zero too.

I don't see any reasons why it cannot be done.
Let's see what I can do. Donations are not mandatory but always appreciated. Wink

The kernel is done. Let's see if this actually works...

All the coding is done, and I'm debugging right now...

Thanks! It is taking longer than I expected, but I will definitely let you know when I'm done.

Actually, given the increased memory requirement, it probably makes more sense to rewrite SA v5's kernel instead.
I should take care of the ASM stuff first, then. I am over the hump with it, so it *shouldn't* take much longer...
