Abstract: A parallel multiprocessor system includes a packet-switching communication network comprising a plurality of processor nodes operating concurrently in parallel. Each processor node generates messages to be sent simultaneously to a plurality of other processor nodes in the communication network. Each message is divided into a plurality of packets having a common destination processor node. Each processor node has an arbiter that determines an order in which to forward the packets onto the network toward their destination processor nodes and a network interface that sends the packets onto the network in accordance with the determined order. The determined order operates to substantially avoid sending consecutive packets from a given source processor node to a given destination processor node and to randomize the destination processor nodes of those packets presently traversing the communication network.

Abstract: An educational institution (also referred as a university) is rich with multiple kinds of data: students, faculty members, departments, divisions, and at university level. Relating and correlating this data at and across various levels help in obtaining a perspective about the educational institution.

Particularly, in the present invention, a resonant inductor and a resonant capacitor of the resonant unit and a load resistor of the output unit constitute a serial resonant circuit having a serial resonant frequency; therefore, when the circuit frequency is operated on the serial resonant frequency, the resonant inductor impedance would be offset by the resonant capacitor impedance, such that the circuit is operated in the zero current switch (ZCS) region, and the output voltage variation can be controlled in ±0.2%. Moreover, through the serial resonant circuit, the issue about the resonant components hard to be designed due to their small characteristic impedance can simultaneously be improved.
