dear amd dev team,
i am using ubuntu 10.04 x64, amd APP SDK 2.8 and the AMD Catalyst Driver 12.10.
Now i tried to profile my OpenCL kernel with the CodeXL 1.0 and i get some discrepancies of the measured values. See the attached figures:
You can see that the VGPR and SGPR usage of the kernel occupancy tab is not consistent to the values of the performance counter tab. So which ones i should trust?
Also i got VALUUtilization, CacheHit and MemUnitStalled values, which are far away from the 100% border. Are they per mille instead of per cent, or why they are greater than 100%?
