[clAmdBlas] Some problems using clAmdBlasTune tool
Hi all,
I am trying to import clAmdBlas library (particularly the GEMM algorithm) into OpenCV's OpenCL module.
The tune program looks to be the right thing I looked for improving algorithm performance. However it turns to crash in the middle of running process. The execution command is like this:
bin32/clAmdBlasTune.exe --store-kernels --float --GEMM
Every time I run the program it will crash at a percentage of GEMM tuning process. When I start it over again the percentage will increase a bit, but will then crash as usual.
I am using 64bit Windows 7 system, however; I used 32bit tune program as I need 32bit libraries for the OpenCV project.
Alternatively, if I run 64bit tune program, there is another problem arises, which is some clc kernel compiling error like this:
\Users\CARLZH~1\AppData\Local\Temp\OCLEDFF.tmp.cl", line 342: error: a
value of type "float4" cannot be assigned to an entity of type "int"
pC[mad24(7u, ldc, 3u)] = tempC7;
^
errors detected in the compilation of "C:\Users\CARLZH~1\AppData\Local\Temp\O
DFF.tmp.cl".
ernal error: clc compiler invocation failed.
Here is my clinfo. I am on a windows 7 64bit. I have AMD APP SDK 2.7 and clAmdBlas v1.8 beta installed; there is also another platform supported by Intel OpenCL SDK. My graphic card is ATI Mobility Radeon HD 5650.
ernal error: clc compiler invocation failed.

I ran clAmdBlasTune.exe on Tahiti. Unfortunately, I could not reproduce your problem. By the way, the commandline parameters passed to clAmdBlasTune.exe are case sensitive: --GEMM should be --gemm.

Are you saying that this program is able to complete on 64bit Windows but not 32bit Windows? (did you test both?)
I also had several problems with tune tool on Linux as well...It appears to be notoriously unreliable.

I read the thread you posted but there seems no solution to my problem. The engineer said they could complete the tuning on their machines. However I have tried several machines with different architectures and specs, none could finish at 100%.
