Abstract: A remotely managed expandable multi-user computer system is provided. The computer system includes a removable compute cartridge and a removable storage cartridge allowing easy upgrade of the computer system. The computer system self-configures when powered on to allow remote management by another system over a network. Automatic failover support is provided without the need for a separate compute element. A self-configurable removable secure-to-wireless converter to couple to a client computer system allows secure communications between the multi-user system and the client computer system via a wireless network.

Abstract: Scheduling the processing of threads by scheduling a datagram from an input queue among a plurality of input queues to a thread for processing. The scheduling includes computing an output position in an output queue, communicating with a plurality of threads for processing, and assigning the datagram to one of said plurality of threads for processing. After processing the datagram, the processing thread enqueus the datagram in the output queues at the output position specified by the scheduled output position.

Abstract: A method of and apparatus for associating units of data with threads of a multi-threaded processor for processing, and enabling each thread to perform processing for at least two of the data units during a thread execution period. The thread execution period is divided among phases, and each of the data units processed by a thread is processed by a different one of the phases.

Abstract: A mechanism to process units of data associated with a dependent data stream using different threads of execution and a common data structure in memory. Accessing the common data structure in memory for the processing uses a single read operation and a single write operation. The folding of multiple read-modify-write memory operations in such a manner for multiple multi-threaded stages of processing includes controlling a first stage, which operates on the same data unit as a second stage to pass context state information to the second stage for coherency.

Abstract: A pulley guides a cable on an overhead framework structure which is suspended from a ceiling by a threaded rod. The pulley includes a guide structure which guides the cable longitudinally through the pulley, and further includes a bracket structure which mounts the guide structure on the threaded rod. The guide structure can be mounted on the threaded rod in a first position in which a cable can be moved transversely into and out of the guide structure, and can be alternatively mounted on the threaded rod in a second position in which the cable cannot be moved transversely into or out of the guide structure.
