Parallel Calibration

List of internally parallelized calibration tasks
Some of the calibration tasks are internally parallelized and will run in parallel if the input MS is a Multi-MS. Other tasks are not and will work normally in the presence of an input MMS. A typical calibration cascade will work normally in parallel when it sees an input MMS. In order to do that, the first step is to set createmms=True inside importasdm to create a Multi-MS. Once that is done, the calibration steps will distribute the processing in parallel if CASA is started with mpicasa, or in serial otherwise.
 
Contrary to the MS, the calibration tables created by calibration tasks are not partitioned. For instance, when gaincal is run on a Multi-MS, it will create the same output gaincal table as if the input was a normal MS.
 
The following calibration tasks are internally parallelised and will work on each Sub-MS in parallel.
