Originally posted by: zhuzxy My workitems need do some computing on a image regions. and I don't know the max sz for the private mem in the A3850. To make the wavefronts number maxmized, the private mem sz is important. Can anyone tell me how to get the private memory sz on A3850? Thanks
Register size is 128KB or 256KB based on GPU. There is no way to get this value from runtime. I don't see any importance of knowing this value.
You can get number of registers used per thread from AMP APP profiler. Please see following counter values from AMD APP profiler
GPRs and ScratchRegs.
