    Mapping a large matrix to NDRange?


      If I have 2 large matrices (say, 10K x 10K) I wish to muliply, too large to completely reside on any GPU device, how should I map it to the NDRange? How do I divide up the problem?

      How best should I define NDRange? Obviously work_dim=2, but what about global_work_size and local_work_size?

      Obviously, only part of each matrix could be loaded.  This is more of a question about global_work_size and local_work_size.
