    CAL vs. OpenCL


      Hi guys,

      Probably a dumb question, but I can't find the answer.  Under the 2.0 SDK, there are CAL and OpenCL samples.  However, I can't find any references to CAL in the documents (no programming manual or command references).  There are references to IL, but not CAL.  Is CAL ATI's API (like CUDA is to NVIDIA)?  If so, is there a performance increase over OpenCL on ATI GPUs?
