mpi_alm2map_slave


This subroutine complements the master routine mpi_alm2map, and should be run by all slaves in the current MPI communicator. It is run without arguments, but after an appropriate call to initialize_mpi_alm_tools.

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


FORMAT

call mpi_alm2map_slave( )


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_alm2map(alms, map)
else
call mpi_initialize_alm_tools(comm)
call mpi_alm2map_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 alm2map operation, and 3) frees the previously allocated memory.
