Importantly, I have 12 GPUs in every node, with an i3-7100 cpu. The nodes with gtx1070ti keep the CPU at 100% utilisation (on both 1.45 and 1.46/1.47) and the GPUs cannot handle anything else (even nvidia-smi fails, takes 5 minutes to show 1 line).

Try --watchdog 0 --pec 0 options to temper gminer's thirst for NVML calls. And, I guess, you have old nvidia drivers like 3xx.something. Try 4xx branch, it's kinda optimized for multi-gpu environment--less LA, more responsiveness.

p.s. @Zminer777, it would be nice to add smth like --no-nvml option, it'll help a lot.

As I said above, I'm using 415.29 drivers, cuda10.0. I'm also already using --pec 0 and --watchdog 0. None of these are an issue though, since the problem is only on gtx1070ti and not on gtx1070. I've tried even newer drivers (no luck).

p.s. this problem of 100% cpu on gtx1070ti (but not on gtx1070) exists for all other algos with Gminer, but not with other mining software, suggesting the problem is Gminer, not drivers or hardware.

I have same issues with multiple rigs with 13mining cards. All running ubuntu linux GMiner takes 100% CPU usage with Core i3, Core i5 and Core i7. It just kills it. I can mine GMiner with under 10GPUs but anything over that will cause rejected shares and 100% CPU usage. I am getting bit better results with 1.41. It still hits 100% CPU time but will mine with less rejected.

This is 19GPU with Core i5 7500.
