Parallel Imaging

The parallelization of imaging is achieved through task tclean. The parallelization itself is tied closely to the major-minor cycles of the imager and follows a different approach of that used by other tasks. The parallelization inside tclean does not need the MS to be partitionted into a Multi-MS. It will work in the same way if the input is an MS or MMS. But in order to run tclean in parallel it is necessary to launch CASA with mpicasa, in the same way as for other tasks. One extra step necessary to run tclean in parallel is to set the parameter parallel=True. All the details of the parallelization are described in the section mentioned above.
