Debugging action items :

• [x] Factor scrblnrd3 code into HiPerC layout for differential analysis
• [x] Read OpenCL spec to understand what, exactly, clCreateProgram and clCreateKernel are doing
• [x] Using gdb, set breakpoint just before clCreateKernel and print addresses and values of OpenCLData struct leading into segfault
• [x] Suspend all but one program with one kernel and test
