[Key] grid.DeadlockDelay [Default] 10 [Description] 
The time, in seconds, the running nodes can be stalled during an ongoing computation. While a computation is in progress, the Master node, node 0, will query the state of executing nodes. If any node fails to indicate progress over a period longer than this parameter, the grid computations will be halted and an error returned. This parameter must be in the range 1 to 60 seconds.
