since 1.3.8 i noticed a drop in keccak performance (7.1GH v1.3.7a) vs (6.6GH v1.3.8+) could you take a look ? (6x1080Ti rig)

I'll take a look into this. We haven't made any changes on keccak though.

I finally had some time to look at this.

Platform: Windows
Driver version: 390.65

Excavator version: 1.3.7a_nvidia | 3456 | 2017-11-17 13:26:36
GeForce GTX 1080: speed = 1.00 GH/s, 0.00 H/s, power usage = 179.39 W

Excavator version: 1.4.1a_nvidia | 4380 | 2018-01-22 10:16:39
GeForce GTX 1080: speed = 1.00 GH/s, 0.00 H/s, power usage = 179.11 W

It looks fine. I tested it on 1080 (not 1080 Ti) though, but it shouldn't be a difference. Which OS are you using?

I use windows 10 enterprise, lemme recheck with 1.4.1 in both cuda 8 and 9

Yeah with 1.4.1 it's back to proper numbers, thanks for publishing this
