Add flag
useCrossRegionCommunicationtopimShiftElementsLeftandpimShiftElementsRight. If true, shift normally. If false, assume that PIM cannot shift across region boundaries. If false, do not model function or performance of shifting across regions. This will be used to benchmark options for cross region communication for stencil/string matching.Does not add flag for
pimRotateElementsLeft/pimRotateElementsRightbecause handling the end elements for a rotation requires cross region computation.
