A method for performing computations associated with bodies located in a computation region includes, for each subset of multiple subsets of the computations, performing the computations in that subset of computations, including accepting data of bodies located in each of a plurality of import regions associated with the subset of the computations, the import regions being parts of the computation region; for each combination of a predetermined plurality of combinations of multiple of the import regions, performing computations associated with sets of bodies, wherein for each of the sets of bodies, at least one body of the set is located in each import region of the combination.

Zonal methods for computation of particle interactions

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.

Parallel computer architecture for computation of particle interactions

A parallel processing system for computing particle interactions includes a plurality of computation nodes arranged according to a geometric partitioning of a simulation volume. Each computation node has storage for particle data. This particle data is associated with particles in a region of the geometrically partitioned simulation volume. The parallel processing system also includes a communication system having links interconnecting the computation nodes. Each of the computation nodes includes a processor subsystem. These processor subsystems cooperate to coordinate computation of the particle interactions in a distributed manner.

Systems and methods are provided for delivering a discount using a partner-issued currency or a combination of virtual currency and partner-issued currency, offering a high-perceived savings value to an end-user while maintaining the perception of product value. An embodiment of an inventive method includes presenting a display of a price paid by a consumer without access to the virtual currency along with a display of an amount payable by the end-user in actual currency in combination with an amount payable in virtual currency. The end-user perceives a benefit to using the virtual currency and since the price paid in actual currency is less than the displayed price to be paid by a consumer without access to the virtual currency.

System and method for providing a discount

In particular, systems and methods are provided for delivering a discount using a virtual currency. Inventive systems and methods offer a high perceived savings value to an end-user while maintaining the perception of product value. Further, systems and methods for providing a discount are described which impose little or no cost on the service or product provider. An embodiment of an inventive method includes presenting a display of a price paid by a consumer without access to the virtual currency along with a display of an amount payable by the end-user in actual currency in combination with an amount payable in virtual currency by an end-user of an inventive system. The end-user perceives a benefit to using the virtual currency since the price paid in actual currency is less than the displayed price to be paid by a consumer without access to the virtual currency.

The invention includes a method and associated software and a system in which bodies are spatially partitioned among computational nodes and wherein each computational node maintains data for a different subset of the bodies. The method includes, importing body data from a set of one of more spatially neighbor nodes and, computing data characterizing interactions between bodies.

Orthogonal method

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.

A method and a corresponding software and a system for processing a charge distribution according to a spreading function and a predefined operation are described.

Grid based computation for multiple body simulation.

The present invention is directed to a system for the electronic trading of financial instruments, and in particular, a system and method for the receipt, combination, and evaluation of equity portfolios for possible simultaneous execution by a sponsor at passively determined prices. In accordance with an embodiment of the present invention, a method for trading securities portfolios includes receiving a first intended portfolio trade having an associated specified commission, evaluating a combination of the first intended portfolio trade and a second intended portfolio trade for possible execution; and transmitting a decision on whether to execute the combination of the first intended portfolio trade and the second intended portfolio trade.
