We have another speedup ready, mostly beneficial to GDDR5X cards (Titan X Pascal will go over 600 for sure). Stock GTX 1070 gets 390 Sol/s.
We have decided to release source of miner and open it up to work on every pool in near future. We will prepare full statement why we have decided that.
Regarding linux: somewhere along the line of optimisations, linux version simply stopped working correctly (is giving incorrect results). We do not have enough man power (+ there are holiday times) to track down the issue, but I am sure community will find it and fix once we release the source.
Weird, interested to hear why that is... I could understand opening up to pools and making it a fee based miner, but open source is something else entirely.
Maybe has something to do with the first release by nicehash, which was open source and used work by a few different contributors. Although there is no doubt nicehash has made a great many optimizations to the CUDA code, which will be really interesting to see. This is great news for miners and also very generous by nicehash for sure!
I'm actually thinking Nicehash coders have reached a brick wall and they're going open source to get 'input' before going closed source again.
BTW Nicehash as I've asked in other threads, consider tackling Cryptonote. The code basically hasn't been touched in years and it's a pretty big economy. Definitely something worth taking a look at.
