Abstract: An arrangement having a processor electrically to, and mounted on, a portion of a surface of a motherboard. A plurality of memory cards is plugged into memory board slot type connectors on a surface of the memory card printed circuit board with the surface of the memory card printed circuit board being perpendicular to the surface of the motherboard. A right angle backplane connector has a first end disposed perpendicular to, and electrically connected to the surface of a motherboard and a second end disposed on the surface of, and electrically connected to, the memory card printed circuit board. The plurality of memory cards is parallel to the surface of the motherboard. An ejector mechanism is provided for removing the memory printed circuit board from an electrical connector receptacle mounted to the motherboard by camming action.

Abstract: A distributed computer system that enables end users to evaluate a broker's trade settlement performance by market and across multiple markets in terms of how many of the broker's trades failed. Trades are defined as having failed when the actual settle date exceeds the date on which the trade should have settled. The system analyzes trade settlement statistics about each broker within the context of a selected broker peer group, and ranks and compares a broker's settlement performance relative to the peer group. The system also ranks the brokers based on a set of metrics relative to the selected peer group. A broker's peer group is defined in terms of the broker's relative size within the trade universe as determined by trade count.

Abstract: An interrupt controller enables multiple CPUs to control access to an increased number of interrupts. Each of a plurality of CPUs is able to block interrupts written to the interrupt controller at multiple levels. First, each CPU is able to block interrupts at the interrupt level. In other words, a CPU is able to block one or more individual interrupt requests from I/O devices from being sent to that CPU. Second, each CPU is able to block interrupts from one or more entire MSI interrupt registers from being sent to that CPU. The interrupt controller is fully programmable by the CPUs in software and thus is very flexible, as the priority of interrupts can be controlled by the CPUs according to the requirements of the CPUs based on the various operational demands of the CPUs. Any of 512 possible interrupt requests are capable of being routed to any particular one CPU, any combination of the CPUs or to all of the CPUs.
