The PARALLELSERVERTARGET parameter is the all important concurrency slider here. Setting this parameter to a higher number means more statements get to run at their maximum parallel degree before queuing kicks in. PARALLELSERVERTARGET is set per instance (so needs to be set to the same value on all 8 nodes in a full rack Database Machine).
