Runtime attributes can be configured within a WDL's task block, but if no value is specified for any one of the customizable attributes your task will run with the default runtime attribute value. The chart below shows the defaults for each runtime attribute, and how to customize to a value of your choosing.
For more information on runtime attributes, please see Cromwell's Runtime Attribute Descriptions documentation.
