My grafic card is a GeForce 690 GTX, this card has 2 seperate GPU's onboard

My question:
What need i to add to the bat file line off text so that i can run 2 bat files at same time.
So that i can do 2 Manual Sieving files in the same time frame..
Example: 1st Bat file list crunch on 1st GPU and the 2nd bat file list on the 2nd GPU.

1st bat file: GFNSvCUDA-0_7-win32.exe 16 9658 9659
2st bat file: GFNSvCUDA-0_7-win32.exe 16 9661 9662

As a test iam now running these 2 bat files at same time, but i see that ONLY 1 GPU is been in use for this...

Temperature 1st GPU 0 = @ 60 dgrC = 100% use
Temperature 2nd GPU 1 = @ 29 dgrC = 0% use

Note:
I do not have to worry about the temperature getting to high, becouse iam using the program TThrottle (http://efmer.com/b/)
With this program you can set a max temp, and the programm do the rest to keep your GPU under that pre set temp.
Works like a charm..

You will need to add "d1" switch to the end of one of the commands so it uses device 1 as well as device 0. You can pause & swap device switches at will if required.

Note that usually you have to run at least two instances of sieve program on each GPU to get 100% GPU usage and maximum possible daily output. Increasing "B" parameter above default "B7" also may help to get more out of it but screen lag becomes noticeable with high values.

Thanks.. Dave

Have done this..

1st bat file > GFNSvCUDA-0_7-win32.exe 16 9658 9659 d0
2nd bat file > GFNSvCUDA-0_7-win32.exe 16 9661 9662 d1

Works now nicely with both GPU's @100% with a max teperature between 57 - 59 dgrC
Both does run there task in aprox. 1h50m
