OpenCL

Hello,

I own a AMD Kaveri A10-7850K APU. I'm trying to find the size of the local data store (LDS). I tried clinfo and obtained 32KB of local memory. However I know from the data sheet that AMD Kaveri belongs to GCN 1.1 architecture and APU based on this architecture has 64 KB LDS. Could somebody explain the reason for the discrepancy?

Please do consider me as a newbie in both opencl & AMD GPU architectures

Thanks a lot in advance !!

Hi,

Yes, you are right. In GCN, the total local memory size/CU is 64KB. But, only 32 KB can be allocated per work-group. So IMO, the clinfo may be showing that number [need to check with some concern person].
