changes required to do this (this enables oclReduction SDK 3.1 to pass
and is a prerequisite to Fermi style concurrent kernel launching)
- separate kernel launch for cuda and opencl (and init_grid functions)
- add pgm_info structure for holding kernel function_info pointer in
_cl_program object after ptx compilation
** added support for clEnqueueNDRangeKernel with local_work_size==NULL
which is part of OpenCL spec and used in oclSortingNetworks (however,
this is a braindead implementation that only handles the case where
global_work_size[0] is smaller than the max number of threads per
shader; moreover oclSortingNetworks is still not working but for what
looks like another reason)
** refactoring / cleanup
- g_global_symbol_table made static to ptx_parser.cc
- remove g_kernel_name_to_symtab_lookup (not really being used)
- moving various function prototypes into headers (e.g., if foo() defined
in bar.cc, then place prototype in bar.h)
- adding icnt_reg_options()

is installed for math intrinsics used in instructions.cc (since
CUDA 3.1 does not seem to define __uint2float).
- currently cuda-math.h has hardcoded paths to my own install of
CUDA 2.3 (need to determine whether we can build simulator with
CUDA 2.3 and run CUDA 3.1 / compute_2x PTX, or need to make
current setup more portable)
- modified ptxinfo.l to print out meaningful error message if
error occurs on first line
- modified ptxinfo.l,y to understand "for 'compute_NN'" syntax
- updated template to 3.1 SDK version
- updated cuda_runtime_api.cc to select highest compute capability
version when multiple versions are present.
- updated template/BlackScholes Makefiles to generate a "DLL build"
instead of static linked build (still confusing... requires one to
copy config files... probably need to modify config scripts)
