Abstract: A system for managing air flow computing devices in a rack includes a stall and filler elements. The stall includes a stall top panel and two side panels spaced apart from one another. The stall accommodates a rack computing system. The filler elements fill gaps between the computing devices of the rack computing systems and the panels of the stalls. An air moving system moves air from the cold aisle through cold-aisle facing air inlets of the computing devices. The filler elements inhibit air moving toward the cold aisle-facing inlets from leaking through gaps between the computing devices of the rack computing systems and the stall panels such that the filler elements inhibit air moving toward inlets in the computing devices from leaking through the gaps between the computing devices in the rack and the stall panels.

Abstract: The technology performs obligations fulfillment monitoring. An input data stream of data messages is received including transaction data and reference data, obligation control logic, and a set of obligation parameters associated with the obligation control logic. An event data processor processes the input data stream using a current version of the obligation control logic and the set of obligation parameters. Subsequently, the event processor receives information to implement and execute obligation control logic that is dynamically-modified and different from the current version of the obligation control logic. The event processor generates and outputs an obligation fulfillment message based on the dynamically-modified obligation logic and transmits to an interested entity.
