A method for dynamically managing memory to support one or more processes executing in a remote direct memory access environment is provided. The device includes a port for receiving a multicast packet and a multicast data structure for maintaining information regarding a multicast group to which the multicast packet is to be sent. The digital circuits are classified into different voltage bins, and each of the voltage bins has a current leakage limit. Interpoint distances between data objects and root term objects correspond to the measures of associative similarity between those points. The bearing 10 has a cylindrical radially outer surface, a central bore 13 with a diameter B and two end faces 12. One of the edges is slanted with respect to the major surfaces and a portion of the optics for coupling light into the substrate is in contact with, or located adjacent to, the slanted edge.
