/*@
MPI_Ineighbor_allgatherv - Nonblocking version of MPI_Neighbor_allgatherv.
Input Parameters:
+ sendbuf - starting address of the send buffer (choice)
. sendcount - number of elements sent to each neighbor (non-negative integer)
. sendtype - data type of send buffer elements (handle)
. recvcounts - non-negative integer array (of length indegree) containing the number of elements that are received from each neighbor
. displs - integer array (of length indegree). Entry i specifies the displacement (relative to recvbuf) at which to place the incoming data from neighbor i.
. recvtype - data type of receive buffer elements (handle)
- comm - communicator (handle)
Output Parameters:
+ recvbuf - starting address of the receive buffer (choice)
- request - communication request (handle)
.N ThreadSafe
.N Fortran
.N Errors
