This is much slower than bminer on Grin. I get only 1.5 h/s for gtx1070. It looks heavily bottlenecked when you have many GPUs on one motherboard. I have 13 gtx1070 on a motherboard, with either G3930 @ 2.9GHz or G4600 @ 3.3GHz. bminer get's me 3.2 h/s per card, 41 h/s total. Gminer barely manages 18.0 h/s in total.

I can also see it's using around 80W per GPU whereas the limit I set was 105W. There is headroom it's not using.

EDIT: ALSO, I forgot to say, it's not finding any solutions!

Using eu-west-stratum.grinmint.com, also tried grin29.f2pool.com

Ubuntu 16.04. CUDA 9.2. drivers 396.54.

bminer has no issues, and it finds about 1 solution every 2 seconds.

Needs a lot more optimisation it seems . Come on, you can do it! I'd like to switch away from bminer.

EDIT2: I switched to CUDA 9.1 with drivers 390.48 and it is now finding solutions, but the speed isn't any better (power usage per gpu is still around 80W only)
