摘要： A generalized approach to particle interaction can confer advantages over previously described method in terms of one or more of communications bandwidth and latency and memory access characteristics. These generalizations can involve one or more of at least spatial decomposition, import region rounding, and multiple zone communication scheduling. An architecture for computation of particle interactions makes use various forms of parallelism. In one implementation, the parallelism involves using multiple computation nodes arranged according to a geometric partitioning of a simulation volume.

摘要： A computation system for computing interactions in a multiple-body simulation includes an array of processing modules arranged into one or more serially interconnected processing groups of the processing modules. Each of the processing modules includes storage for data elements and includes circuitry for performing pairwise computations between data elements each associated with a spatial location. Each of the pairwise computations makes use of a data element from the storage of the processing module and a data element passing through the serially interconnected processing modules. Each of the processing modules includes circuitry for selecting the pairs of data elements according to separations between spatial locations associated with the data elements.

摘要： A method and system for an automated trading network that continuously collects invisible, anonymous, binding orders and indications of interest to buy and sell specific equity securities at variable, passively determined prices and, then, executes trades based on these collected orders and indications. In general, the binding orders are collected from retail broker-dealers and the binding indications are collected from institutions. The variable, passively determined, non-discrete prices can be linked to the National Best Bid or Offer (NBBO) for each security, or some other prevailing market indicator, at the time a trade is executed. In an embodiment of the method and system, marketable retail orders which match with one or more collected institutional indications, are routed from a Dynamic Order Router (DOR) at each broker-dealer to a Central Order-Match Box (COMB) to be executed against the one or more matched collected institutional indications. The COMB also manages most other aspects of transactions in the method and system and continuously executes trades against the collected institutional indications at improved prices relative to the NBBO.
