Plz explain autoconfiguration of blocks and threads
I am interested in how xmrig-nvidia decides what blocks and threads should be used by a GPU. This is because I have three rigs with mixed nvidia GPUs (GTX 750 non-Ti 1 GB, GTX 750 TI 2GB, GTX 770 3GB, GTX 1060 3GB, GTX 1060 6GB), and the autoconfigurated values of b x t nearly always give some errors (mostly "out of memory") on one or more cards.
