template <typename Void>
constexpr std::tuple<Void*, communicator::stride>
normalize_strided_pointer(
Void* ptr,
communicator::stride stride)Description
Strides that only differ e.g. in their dim0 allocation size are equivalent when adjusting the base pointer. This not only improves mpi_communicator type cache efficiency, but is in fact necessary to make sure all boxes that instruction_graph_generator emits for send instructions and inbound pilots are representable in the 32-bit integer world of MPI.
Template Parameters
- Void
- Either `void` or `const void`.
Parameters
- Void* ptr
- communicator::stride stride
