Progress report on the Cuckoo Cycle GPU solver
============

UPDATE
------
This document is obsoleted (in part) by photon's 4x faster GPU solver from early April 2018.

Since completing my rewrite of xenoncat's performance quadrupling CPU solver (winning a double bounty)
in the form of mean_miner.cpp, I've been slowly grinding away at porting that code to CUDA.

I consider myself an amateur GPU coder, having previously ported the latency bound lean_miner to CUDA
(and having to pay a bounty to fellow Dutchman Genoil for improving performance by merely
tweaking the threads-per-block which I had naively fixed at 1), as well as my own
[Equihash miner](https://github.com/tromp/equihash) submission to the
[Zcash Open Source Miner Challenge](https://z.cash/blog/open-source-miner-winners.html).
That Equihash CUDA miner achieved a paltry 27.2 Sol/s on an NVIDIA GTX 980,
matching the performance of my Equihash CPU solver. But it did serve as the basis for far more capable
rewrites such as this
[Nicehash miner](https://github.com/nicehash/nheqminer/blob/master/cuda_djezo/equi_miner.cu)
by Leet Softdev (a.k.a. djezo), which achieves around 400 Sol/s on similar hardware.
