4.6.7. Displaying Resource Availability on ARC Nodes (arcnodes)

Use the arcnodes command in the ARC command directory to view the cores, memory and disk space available for job execution on ARC execution nodes at any given time.

To view resource information for a specific node, append the node's machine name to the command:

arcnodes <nodeName>

If a node name is not provided, the command will list information for all execution nodes, as shown below:

                                                      Cores            Memory           DiskSpace
Exec Node Name   Associated Master   State     Avail   Max     Avail     Max     Avail     Max

    * Indicates that resources have not been set up.  Any resource request will be accepted.

The available cores, memory and disk space will vary depending on how much is currently being consumed by jobs.
