Gather-to-all

void Intracomm.Allgather(Object sendbuf, int sendoffset,
                         int sendcount, Datatype sendtype,
                         Object recvbuf, int recvoffset,
                         int recvcount, Datatype recvtype)
Java binding of the MPI operation MPI_ALLGATHER. Arguments as for Gather, except for the omission of root.

void Intracomm.Allgatherv(Object sendbuf, int sendoffset,
                          int sendcount, Datatype sendtype,
                          Object recvbuf, int recvoffset,
                          int recvcount, int [] displs,
                          Datatype recvtype)
