SW compiles kernel with vectorization factor = 8, while HW only support 4 vector width. In such case, most ops/execution on II cycles won't change, but the index-related (vectorization factor related) variables cannot change unless the vector execution reaches its bound. https://www.comp.nus.edu.sg/~tulika/FLEX_ICCAD.pdf
Above temporal vector execution requires global synchronization if the kernel is dynamically mapped onto two CGRAs.
