I have a problem similar to this topic clBuildProgram performance and limits?
I'm trying to compile OpenCL program on my 7850. It is strange that clBuildProgram takes 100s ms.When I using graphic card of other brands, it only takes 1-2 ms.
Is this normal? Or did I use it in a wrong way?
|cl_program program = clCreateProgramWithSource(cl_gpu_context_,1,(const char **)&ptr_program_source,&program_length,&cl_error_num);|
|if(cl_error_num != CL_SUCCESS)|
|cl_error_num = clBuildProgram(program,0,NULL,ptr_build_option,NULL,NULL);|
OS: Win7 64bits
Graphic card: AMD Radeon HD 7850
