Looking for suggestions: Inferring GPU memory accesses
...emory accesses. For how many of
those M accesses we can statically infer its location given concrete values
for the grid/block and executing thread?
(Assume CUDA only for now)
My initial idea is to replace all uses of dim-related values, e.g:
__cuda_builtin_blockDim_t::__fetch_builtin_x()
__cuda_builtin_gridDim_t::__fetch_builtin_x()
and index related values, e.g:
__cuda_builtin_blockIdx_t::__fetch_builtin_x()
__cuda_builtin_threadIdx_t::__fetch_builtin_x()
with ConstantInts. Then run constant folding on the result and check how
many GEPs have constant values.
Would something like this work or ar...
