Abstract: A system for efficiently interconnecting computing nodes can include a plurality of computing nodes and a plurality of network switches coupled in parallel to the plurality of computing nodes. The system can also include a plurality of node interfaces. Each computing node among the plurality of computing nodes can include at least one node interface for each network switch among the plurality of network switches. The plurality of node interfaces corresponding to a computing node can be configured to send data to another computing node via the plurality of network switches. The system can also include a plurality of switch interfaces. Each network switch among the plurality of network switches can include at least one switch interface for each computing node among the plurality of computing nodes. A switch interface corresponding to the computing node can be coupled to a node interface corresponding to the computing node.

Abstract: A flex circuit, which is fabricated from metallization on thin film, is mounted between two opposite sides of frame to form an electronic card sized to fit as a replacement for a rigid epoxy glass card in a card carrier having a backplane. Appropriate placement of electrical components on the flex circuit and using a flex circuit longer than the spacing between the opposite sides of the frame to which the flex circuit is mounted, allows the use of taller parts on adjacent cards in the card carrier, since the flex circuit can be conformed to eliminate obstructions caused by insufficient spacing between cards.
