about catalyst 10.11

about catalyst 10.11

 

  Hi all:

        Recently I installed catalyst 10.11. It's bettter than 10.11 in that now two GPUs are working (in 10.10 only GPU0 works). I wrote a simple program that multiplies nature number by 2, below are the testing result. ( I run export DISPLAY=:0 before every run):

Verifying results for GPU0 : the first 10 reulits for this GPU is:0.000000,2.000000,4.000000,6.000000,8.000000,10.000000,12.000000,14.000000,16.000000,18.000000,Passed!
        Verifying results for GPU1 : the first 10 reulits for this GPU is:0.000000,2.000000,4.000000,6.000000,8.000000,10.000000,12.000000,14.000000,16.000000,18.000000,Passed!
        Verifying results for GPU2 : the first 10 reulits for this GPU is:-84904433160159100468813069988594188288.000000,-nan,-nan,-inf,-42369139830342992992350047053029572608.000000,-nan,-nan,-20687103343954414804234249086959616.000000,-nan,-nan,Failed!
        Verifying results for GPU3 : the first 10 reulits for this GPU is:18558779392.000000,0.000000,0.000000,25.004196,-0.000000,-1674.125488,0.000000,-4.253963,0.000217,0.000000,Failed!

       So is there any settings that I have to change or I should wait for even newer catalyst ?    

   I really appreciate any comments on this .

hi thomasUCF,

As per AMD support for second device in 5970 is not available as of now.So you will have to wait for future releases.

   Hi Himanshu:

       Even in Linux System?  I just need a definite answer so I can stop on this.  As a Linux beginner I always try different commands which I don't understand and install different apps, and some times that made my system collapse.

  Thanks a lot.

I think you are aware that some users have been able to use multidevices for 5970.http://forums.amd.com/devforum/messageview.cfm?catid=390&threadid=140518&enterthread=y

But AMD officially do not support it for now and advices users not to use the second device of 5970.
