ok got some results - GTX 1080 Ti is getting 600+ sols/s - GTX 1070 is getting 350 sols/s peak. More results as i get them. This is not fully optimized for these high ends cards, so there is room for improvement.

Quote from: WelcomeHomeCrypto on October 16, 2017, 09:33:12 PM Wouldn't hurt if you give out some more details about the miner, would it? What GPUs it is designed for and should work on, what performance you are getting on what GPUs... things like that can help get people attention. Okay, I designed it for NVIDIA at the start, but AMD and Intel Gpu's work pretty good too. Its programmed in OpenCL, so it should be compatible with any gpu's and CPU's with OpenCL 1.2 support. The issue is I dont have any "high" end GPU's to test with, so I dont know the performance on them. GTX 650 - 13-17 sols/s AMD Oland - ~20 sols/s Intel HD4000 - 8-10 sols/s Uses ~580MB of GPU memory and Uses very little cpu time (except with some intel gpu's due to driver). For comparison EBWF gets 16-17 sols/s on my GTX 650.

Hello all, I got a Windows build working for my new OpenCL miner, im looking for people to test compatibility. Please check it out at https://github.com/maztheman/nheqminer/releases/tag/BETA1 Let me know if there is a gpu that is not working at all, or has terrible performance. Anyhow, thanks in advanced for testing it for me! maztheman

Looks like it was a combination of slightly off algorithm for collision detection and majorly bugged hashing algorithm. The hashing algorithm was causing the wrong solutions to be posted to the pool, and potentially correct solutions being lost. I have started from scratch and it looks like solutions are being found and at a good rate too.

No, it didnt work. Only a few shares got sent to the pool and they were all rejected due to too low difficulty. Im testing my miner's solutions vs other 3rd party miners. I must have a bug in my algorithm. Ill post some more once I figure out anything.

its a local pool I am running from my pc, a z-nomp pool.

Hello, I need some help with my OpenCL Miner for ZCash. It finds solutions but the pool keeps rejecting as "too low difficulty". I think when I find solution, im not sure i sorted the indexes properly. Is there a test case that has input and expected output?

(There was a bug in the code.) I am also thinking about rewriting GG in CUDA for a better performance. The miner is already running 40% faster on GTX 1060, but I need an extra boost to catch up with Eqminer. I made cuda port of SA5, no difference in performance vs opencl+nvidia cpu load fix. The only one thing that cannot be implemented in opencl is cudaDeviceSetCacheConfig. In openCL you can inline nvidia ptx asm easy, like in cuda. Thank you so much for letting me know. What I specifically had in my mind was "shfl." If that instruction can be exposed through inline PTX, I can save a considerable amount of time. Yeah you can but check the compute version needed, I think its compute 3.2+.
