[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.
