mpi_alm2map_simple*


This subroutine provides a simplified (one-line) interface to the MPI version of alm2map. It supports both temperature and polarization inputs in both single and double precision. It must only be run by all nodes in the MPI communicator.

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


FORMAT

call mpi_alm2map_simple*( comm, alms, map )


ARGUMENTS

name & dimensionality kind in/out description
       
comm I4B IN MPI communicator.
alms(1:nmaps,0:lmax,0:nmax) SPC or DPC IN Input alms. If nmaps=1, only temperature information is included; if nmaps=3, polarization information is included
map(0:npix,1:nmaps) SP or DP OUT Output map. nmaps must match that of the input alms array.


EXAMPLE:

call mpi_alm2map_simple(comm, map, alms)
This example executes a parallel map2alm operation through the one-line interface. Although all processors must supply allocated arrays to the routine, only the root processor's information will be used as input, and only the root processor's alms will be complete after execution.
