Load thresholds are needed if you deliberately oversubscribe your machines, and you need a mechanism to prevent excessive system load. Suspend thresholds are also used for this. The other case in which load thresholds are needed is when the execution node is open for interactive load which is not under control of Grid Engine, and you want to prevent the node from being overloaded. If a compute farm is more single-purpose, e. g., each CPU at a compute node is represented by only one queue slot, and no interactive load is expected at these nodes, then load_thresholds can be omitted. To disable both thresholds set load_thresholds to none and suspend_thresholds to none. See queue_conf(5).
