Hi,
I just bought ATI Radeon HD 4600 series also HD 5670. I tried to get the information from my program (I use the 4600), the result is shown below:
Device name: ATI RV730
Device vendor: Advanced Micro Devices, Inc.
Device profile: FULL_PROFILE
Device version: OpenCL 1.0 ATI-Stream-v2.2 (302)
Driver version: CAL 1.4.815
Max clock frequency (MHz): 750
Global memory size (MB): 256
Maximum size of memory object allocation (MB): 128
Global memory cache size (MB): 0
Local memory size (KB): 16
Max Work Group size = 128
Max Work Item dimensions = 3
Max Work Item sizes = 003BBD48
Number of parallel compute cores = 8
Endianess = LITTLE ENDIAN
The question: I doubt about the correctness of the "Max Work Item size" information. I think I did some mistake in the code.
Here is the part of my code:
status = clGetDeviceInfo(devices[0], CL_DEVICE_MAX_WORK_ITEM_DIMENSIONS, sizeof(cl_uint), (void *)&maxWorkItemDimensions, NULL);
cout <<"\tMax Work Item Dimensions = " << maxWorkItemDimensions << endl;
maxWorkItemSizes = (size_t *)malloc(maxWorkItemDimensions * sizeof(size_t));
status = clGetDeviceInfo(devices[0], CL_DEVICE_MAX_WORK_ITEM_SIZES, sizeof(size_t)*maxWorkItemDimensions,(void *)maxWorkItemSizes, NULL);
cout << "\tMax Work Item Sizes = " << maxWorkItemSizes << endl;
Can someone point out my mistake?
I also try to query using CL_DEVICE_LOCAL_MEM_TYPE, but it can not found a "CL_LOCAL" type? Is this correct?
Thank you very much
