mpi_cleanup_alm_tools

This subroutine deallocates any private arrays previously allocated in the mpi_alm_tools module. It should be run (without arguments) by all processors in the current communicator after the last call to any of the working routines.

Location in HEALPix directory tree: src/f90/mod/mpi_alm_tools.f90 

FORMAT

call mpi_cleanup_alm_tools( )

ARGUMENTS

None.

EXAMPLE:

call mpi_comm_rank(comm, myid, ierr)
if (myid == root) then
call mpi_initialize_alm_tools(comm, nsmax, nlmax, nmmax,
zbounds,polarization, precompute_plms)
call mpi_map2alm(map, alms)
else
call mpi_initialize_alm_tools(comm)
call mpi_map2alm_slave
end
call mpi_cleanup_alm_tools

This example 1) initializes the mpi_alm_tools module (i.e., allocates internal arrays and defines required parameters), 2) executes a parallel map2alm operation, and 3) frees the previously allocated memory.
