    OpenCL LDS on 4870

    bayoumi

      Although the ATI OpenCL manual says that LDS is not supported for R7xx family, I seem to be writing ocl code whice uses LDS & local threads, plus barriers, and seems to be giving the correct results, using the HD4870 X2?

      It is not complaining during compile or run time. Probably the performance is not ideal, but is it some how using the smaller LDS or is using registers?

       

      Thanks
