MPI.Win_create(base::Array, comm::Comm; infokws...)

Create a window over the array base, returning a Win object used by these processes to perform RMA operations

This is a collective call over comm.

infokws are info keys providing optimization hints.

MPI.free should be called on the Win object once operations have been completed.

MPI.Win_create_dynamic(comm::Comm; infokws...)

Create a dynamic window returning a Win object used by these processes to perform RMA operations

This is a collective call over comm.

infokws are info keys providing optimization hints.

MPI.free should be called on the Win object once operations have been completed.

(win, ptr) = MPI.Win_allocate_shared(T, len, comm::Comm; infokws...)

Create and allocate a shared memory window for objects of type T of length len, returning a Win and a Ptr{T} object used by these processes to perform RMA operations

This is a collective call over comm.

infokws are info keys providing optimization hints.

MPI.free should be called on the Win object once operations have been completed.
