Grid Support Functions and Tools
• Support functions and tools allow end users to
– Verify that the specific Grid resources they require are available
by checking basic functionality such as authentication, file
transfer, and job submission,
– Check that their applications and files exist on the Grid resource,
– Make sure that user security settings are configured correctly.
• Matlab functions are available.
• They are also integrated to the workflow editor.
