I'm curious if I could run to instances of ccminer using my 4 - 750ti.
1 instance calling 2 cards to run GRS and 1 instance calling 2 cards to run on FC.
I honestly have no idea if this is possible.
no promises but it might just work by default. The other night I accidentally (quadrupal?) clicked my Groestl_start.bat and went to bed. The bat launched twice. so when I went to look in the morning, I had two ccminer cmd windows open, and each one was reporting back half my expected hash rate. It did take a reboot to get one single instance running back at full hash however.
Maybe Chris B can weigh in. There must be a way to indicate which GPU threads you want to use.
I've heard some chatter that running two miners at once can be beneficial. I haven't investigated this or know which miner / algo they were talking about. My guess is it didn't hinder you at all.
The GPU callouts are in the ccminer readme. It does work. I also accidentally called out 1 GPU by mistake once. Looking at precision x and the config it became obvious.
I'm going to try it later today and see what happens. I now have no reason to doubt it wouldn't work.
