I have an issue similar to https://community.amd.com/thread/166307.

 

I have the issue with OpenCL not recognizing the 295x2 properly in my system.
$ aticonfig --lsa
* 0. 05:00.0 Supported device 67B9
  1. 06:00.0 Supported device 67B9
  2. 83:00.0 Supported device 67B9
  3. 84:00.0 Supported device 67B9

 

* - Default adapter

 

clinfo | grep "Board name\|Device Topology"
  Board name:                     AMD Radeon R9 200 Series
  Device Topology:                 PCI[ B#5, D#0, F#0 ]
  Board name:                    
  Device Topology:                 PCI[ B#5, D#0, F#0 ]
  Board name:                    
  Device Topology:                 PCI[ B#5, D#0, F#0 ]
  Board name:                    

 

My system is RHEL 6.5 on a dual Xeon ASUS Z10PE-D8 WS motherboard.

 

As you can see aticonfig recognize 4 GPUs (0x05, 0x06, 0x83, 0x84) which are the two(2) 295x2 in the system.  The clinfo only recognize three(3) and it showed all of the same PCI bus ID (B#5).

 

I'm having an issue with multi-GPU OpenCL and I'm hoping that somehow OpenCL is not being recognized properly (the above) issue is the cause of my Multi-GPU issue.

 

I have a beta test coming up next week and this issue is holding me up.
Thank you in advance for your prompt reply.

 

Additional info.  I've tried this both fglrx-15.504 and fglrx-15.5.  OpenCL is using the v3.0 beta sdk.
