1416 : !! FUNCTION
1417 : !! Redistribute an array of paw_an datastructures
1418 : !! Input paw_an is given on a MPI communicator
1419 : !! Output paw_an is redistributed on another MPI communicator
1420 : !!
1421 : !! INPUTS
1422 : !! mpi_comm_in= input MPI (atom) communicator
1423 : !! mpi_comm_out= output MPI (atom) communicator
1424 : !! mpi_atmtab_in= --optional-- indexes of the input paw_an treated by current proc
1425 : !! if not present, will be calculated in the present routine
1426 : !! mpi_atmtab_out= --optional-- indexes of the output paw_an treated by current proc
1427 : !! if not present, will be calculated in the present routine
1428 : !! natom= --optional-- total number of atoms
1429 : !! ----- Optional arguments used only for asynchronous communications -----
1430 : !! RecvAtomProc(:)= rank of processor from which I expect atom (in mpi_comm_in)
1431 : !! RecvAtomList(:)= indexes of atoms to be received by me
1432 : !! RecvAtomList(irecv) are the atoms I expect from RecvAtomProc(irecv)
1433 : !! SendAtomProc(:)= ranks of process destination of atom (in mpi_comm_in)
1434 : !! SendAtomList(:)= indexes of atoms to be sent by me

1439 : !! if present, the redistributed datastructure does not replace
