High CPU usage with more cards #203

Open Eneen opened 6 years ago

When run on 13x1070ti rig ccminer takes almost 100% of 1 CPU thread on neoscrypt. Mining is about 5-10%slower then on 7 card rig. I've got pentium 4560 2c/4t 3.5GHz, hope some tweaks can be made to optimize cpu usage. If not please close and I'll just get faster CPU. System: linux, hiveos.

3 days ago I have added the option --cuda-schedule Maybe you could try this. --cuda-schedule 0 is the default, but maybe it works better with --cuda-schedule 2 in your case.

Will this be in the .21 release? What does it do?

When the gpu is hashing the CPU has nothing to do in the meantime. With this option you can choose what the CPU willl do. The best setting depends on your system and your preferences. It's a balance between CPU load and speed, basically.
