/*@
MPI_Raccumulate - Accumulate data into the target process using remote memory
access and return a request handle for the operation.
'MPI_Raccumulate' is similar to 'MPI_Accumulate', except that it allocates a
communication request object and associates it with the request handle (the
argument request) that can be used to wait or test for completion. The
completion of an 'MPI_Raccumulate' operation indicates that the origin buffer is
free to be updated. It does not indicate that the operation has completed at
the target window.
Input Parameters:
+ origin_addr - initial address of buffer (choice)
. origin_count - number of entries in buffer (nonnegative integer)
. origin_datatype - datatype of each buffer entry (handle)
. target_rank - rank of target (nonnegative integer)
. target_disp - displacement from start of window to beginning of target
buffer (nonnegative integer)
. target_count - number of entries in target buffer (nonnegative integer)
. target_datatype - datatype of each entry in target buffer (handle)
. op - predefined reduce operation (handle)
- win - window object (handle)
Output Parameters:
. request - RMA request (handle)
Notes:
The basic components of both the origin and target datatype must be the same
predefined datatype (e.g., all 'MPI_INT' or all 'MPI_DOUBLE_PRECISION').
