8.1. The MAST section

The $mast section contains this keyword:

system_name: Specify a single descriptive word here.

This keyword will become part of the recipe directory’s name, and allow you to spot the recipe more easily in the $MAST_SCRATCH directory.

This keyword comes in handy with pegged looping, in order to help you identify loops.

• Loops are otherwise differentiated by elements, if you were looping over elements, or simply by a 1-second timestamp difference.

Example:

$mast
system_name epitaxialstrain
$end

Example for pegged loop:

$mast
pegloop1 system_name (strain1,strain2,strain3)
$end
