Hello

i would use many HD5870 card under my RedHat linux 5.3 for GPGPU compute.

I have installed ati-opencl-beta-driver-v2.0-beta4-lnx and ati-stream-sdk-v2.0-beta4-lnx64.

i have 4  hd5870 and 1 monitor under each

i make a aticonfig --adapter=all --initial for configure it.
my Xorg.conf is attached

when i start my Xserver , i have the badge "AMD Testing Use  only" in right-bottom of each monitor

in the amdcccle, i have 4 screen

for the command :

aticonfig --list-adapters
* 0. 13:00.0 ATI Radeon HD 5800 Series
  1. 0c:00.0 ATI Radeon HD 5800 Series
  2. 8d:00.0 ATI Radeon HD 5800 Series
  3. 86:00.0 ATI Radeon HD 5800 Series

* - Default adapter

 

but when i run FindNumDevices, i have

$./FindNumDevices
Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.467
Use -? for help
CAL initialized.
Finding out number of devices :-
Device Count = 1
CAL shutdown successful.

Press enter to exit...

for lspci i have :

$ /sbin/lspci | grep VGA
0c:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 6898
13:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 6898
86:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 6898
8d:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 6898

...?

ANSWER : how use many hd5870 for compute with CAL??

Thank
