A note on XGA’s parallelism
In every SAS function built into XGA (and indeed many functions in other parts of the module), you will find a num_cores keyword argument which tells the function how many cores on your local machine it is allowed to use. The default value is 90% of the available cores on your system, though you are of course free to set your own value when you call the functions.
To see the number of cores which have automatically allocated to XGA, you can import the NUM_CORES constant from the base xga module. You can also manually set this value globally, before running anything. Either set the num_cores option in the [XGA_SETUP] section of the configuration file, or simply set the NUM_CORES constant imported from xga.
