numNodes

The number of nodes to use with a multi-node parallel job. This value overrides the number of nodes that are specified in the job definition. To use this override, you must meet the following conditions:

• There must be at least one node range in your job definition that has an open upper boundary, such as : or n:.

• The lower boundary of the node range that's specified in the job definition must be fewer than the number of nodes specified in the override.

• The main node index that's specified in the job definition must be fewer than the number of nodes specified in the override.
