« on: September 15, 2014, 07:13:38 pm »could you check a readme file file on -g parameter, clearly said i check the readme and don`t understand how to run(( i will use old one what have -t parameterPerformance numbers without details on OS, Catalyst version and configuration are pretty useless, but 4300 cpm is slow if the newest drivers are used and if the GPU does not run into thermal throttling. The Linux and Windows drivers have totally different characteristics.
also it will be good to have an example.but in all archives.
also i would like to know what is current speed on amd 290? - my shows 4300
I hope that I can explain the use of the -g parameter with some examples. It controls the number of threads which are run on each GPU. Let's assume that you used -t 0,0 previously. That means that you run 2 threads on the device with ID 0. Therefore the new syntax would be -d 0 -g 2. -t 0,0,1,1,2,2,3,3 is equivalent to -d 0-3 -g 2 and -t 0,0,0,1,2,3,3 would become -d 0-3 -g 3,1,1,2. Using the newest Catalyst version on Windows, I have observed that spawning 4 threads per R9 290 and -a 2 gives a significant performance boost (-g 4 -a 2). Please note that the -d parameter is optional. If it is not specified than all AMD GPUs are used by clpts. You can still use the -t parameter but people with many GPUs per rig reported problems and something like -t 0,0,0,0,1,1,1,1 instead of -d 0,1 -g 4 is not convenient.
Ok so if i have 3 gpu in the rig my option will be so
-d 0-3 -a 2 -g 4,4,4
i have win 7 64 catalist 14.6 8 gb ram
with new parameters i write upper i have 5000 cpm om card(stock 947/1250 elpida)
and what cpm did you get?
