yep, the whole work was done by tpruvot, djm, tsiv and others, alexis78 forked or palginmod based of this fork are ok. They are fast and free as original ccminer. For some fckd up reason that SP dude decided that he can take others huge work, change it a tiny bit to add 5-10% hashrate and sell it as a private miner while not paying 95% of his earnings to the original developers. This is outrageous, i hope sp will get a huge d*k in the a for this

It seems tpruvot constantly tries to improve the latest versions and still somehow Alexis78 beats all that in those algo that it supports (neoscrypt, blake2s, nist5, keccak, lyra2v2, C11, mir-gr) and people say that's because of Pascal/Maxwell (aka Paxwell) has hardware implemented CUDA 7.5 features and since then all CUDA versions are are just software emulation, maybe because they've made for GP100 and GV100 chips that look different from any Maxwel or Pascal anyway
