¹ The hints prefixed with sbg: are specific for the Seven Bridges execution environment. CWL 1.0 introduces coresMin / coresMax (minimum and maximum number of CPU cores) and ramMin / ramMax (minimum and maximum amount of RAM) in resource requirements, which can be found on any level (Workflow, Step, Tool). If your CWL 1.0 app description contains only the -Min or the -Max value, the Seven Bridges execution environment will use the specified value as the number of cores or amount of RAM required for execution. If both the -Min and the -Max value are specified, the execution will ignore the -Max value and provide enough resources to accommodate the -Min requirement, in order to provide consistency in execution of apps described using either sbg:draft-2 or 1.0 version of CWL. Finally, if sbg:CPURequirement or sbg:MemRequirement are evaluated along with the corresponding CWL 1.0 -Min requirements (coresMin or ramMin), the execution will use the higher of these two values as the required number of cores or amount of RAM.

Disk space requirements introduced in CWL 1.0 (tmpdirMin / tmpdirMax and outdirMin / outdirMax) are unfortunately not currently supported by the Seven Bridges Platform.
