Hi to the List,

i am new to the Project and i am getting a little confused to get the 
best values for my headless system with that cards:

01:00.0 VGA compatible controller: nVidia Corporation GT200 [GTX280] 
(rev a1)
02:00.0 VGA compatible controller: nVidia Corporation GT200 [GTX280] 
(rev a1)
04:00.0 VGA compatible controller: nVidia Corporation GT200 [GTX280] 
(rev a1)
05:00.0 VGA compatible controller: nVidia Corporation GT200 [GTX280] 
(rev a1)

The cgi script generated me a setting for  --device cuda:operations=512, 
i played a little bit around with that value to improve the Speed.

with 512 i got 111 chains/s
with 1024 it was 123 chains/s
with 2048 it is stable with 143 chains/s

After that i searched in the posts from the List and there i found:

blocks and threads can be configured like

--device cuda:blocks=23:threads=42

so which way is the better way ?
can somebody give me a hint which way is better to test ?

Regards

Axel
