A system and method for configuring a plurality of processing nodes into a parallel-processing database system are described herein. The cavity is configured to receive an end of a cable. A charge-pump circuit feeds back a slice-level control voltage to the comparator based on a result of the detection by the dropout detection circuit. The list includes those peers which are predicted to have the best QoS with the requesting peer. At least one of the resilient members is in the form of a flat spring of pin type, consisting of a juxtaposition of elongated wire arms connected in pairs by an elastic joint, where an articulation axis of the elastic joint is perpendicular to a plane containing the respective pair of wire arms.
