Cuckaroom CPU and OpenCL implementations? #240

Closed dagonharett closed 4 years ago

dagonharett commented 4 years ago

AFAICT only the Cuckaroom CUDA implementation is currently working on master (28f39532a5879a49bfed81d9e27aa59ccb773597). Since Hardfork2 is now live, are there any plans to finish both the CPU and OpenCL implementations?

Upon building grin-miner and the OpenCL plugins I got cuckaroo and cuckarood plugins for the CPU and cuckaroo for OpenCL. As expected, they all produce invalid shares on a synced grin node:

ERROR grin_servers::mining::stratumserver - (Server ID: 0) Failed to validate share at height 529882, hash 4af5931a5bfa, edge_bits 29, nonce 6745532596357350798, job_id 3. Err(Error { inner:Verification Error: endpoints don't match up })

It just feels strange that there are no official CPU and OpenCL implementations. Was all the testing done with just the CUDA implementation?

Hi @dagonharett, yes the testing was done with the CUDA solver. I don't personally have the bandwidth to work on an OpenCL solver. So if you are able to implement it, that'd more than welcome (or if you know anyone able to).

Closing this issue as Cuckaroom is going to be phased out pretty soon. CPU and OpenCL implementations would now be useful for Cuckarooz, check #250.
