I have two Nvidia Telsa cards that I use for work, they are good for certain tasks around data mining and machine learning, and I have been interested in trying to use them for Zcash mining. I have a Antminer U3 that mines Bitcoins (slowly, and not that well sometimes), however I fancied a go at mining Zcash too. How hard could it be? Harder than it should have been.
Being Cuda cards I would obviously need a cuda enabled miner to use them. I already mine with Antpool, and they allow users to mine Zcash so that bit was easy. What wasn’t easy was trying to get a miner to compile. I tried nheqminer, that wouldn’t compile and also the newest version doesn’t work with the tesla cards I have as they are not compute 5. The older versions wouldn’t compile either. I also had a few problems with getting cuda running on Kubuntu 16.04 as I needed to upgrade the nvidia drivers which was a pain!
I got there in the end as I found a binary of nanopool’s ewbf-miner that works with cuda cards! This works great, I get about 70 Sol/s on the K20 and 95Sol/s on the K40. So that is pretty good, you would get about 40 Sol/s on a i7-6700K CPU @ 4.00GHz. I am sure that with a newer telsa or CPU you would get more. This only an experiment however, not a mining operation so I am happy.
