Some tests...
A test machine with one 970 and one 750ti, Ubuntu 14.04, ccminer 45, quark algo, compiled with both 50/52 capability
default config (without -d and -g parameters): no performance increase and validate errors
-d 0 -g 2 (only 970 runs): 35% performance increase, no errors
-d 1 -g 2 (only 750ti runs): no performance increase and validate errors
The problem is that the 750ti is out of resources.
I will fix it so that it will give a boost and no validation errors on all the maxwell cards. I just need to reduce the constmem/sharedmem usage and reduce threads per block for the kernals.
I think I will recode the -g parameter to support the -d parameter.
just give me some more time. This will be the biggest boost in hashrates in months..
For a 35% boost I think it is time to include a small developer fee of 2%. What do you think guys?
I will keep the sourcecode opensource and linux compatible.
