Patent number: 9747099Abstract: 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.Type: GrantFiled: November 19, 2012Date of Patent: August 29, 2017Assignee: D.E.

Publication number: 20120116737Abstract: 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.Type: ApplicationFiled: December 19, 2011Publication date: May 10, 2012Applicant: D.E.

Patent number: 7627516Abstract: 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.Type: GrantFiled: October 14, 2005Date of Patent: December 1, 2009Assignee: D. E. Shaw & CompanyInventors: Nicholas P. Gianakouros, David E. Shaw

Patent number: 6516341Abstract: A system for providing scheduled messages to a remote user in a batch oriented system. In a preferred embodiment of the present invention, a user creates and/or reads electronic mail locally. While the user creates the electronic mail, a message is displayed to the user on a portion of the local monitor, the message preferably changing in accordance with a local display schedule and stored on a local storage device. The message is preferably targeted to the particular user. When the user is ready to transmit the e-mail created and/or receive e-mail addressed to him, the user's local client establishes a connection via a modem with a remote e-mail server system. The remote e-mail server system not only receives the e-mail transmitted by the user and/or transmits e-mail addressed to the user, but also updates the user's local messages in accordance with a distribution schedule.Type: GrantFiled: January 25, 2001Date of Patent: February 4, 2003Assignee: Juno Online Services, Inc.Inventors: David E. Shaw, Charles E. Ardai, Brian D. Marsh, Mark A. Moraes, Dana B. Rudolph, Jon D. Mc Auliffe

Patent number: 6311211Abstract: A method of operating an advocacy network is provided. One or more users are selected based on information in a user database containing, for example, demographic or psychographic information about users as well as information identifying a representative associated with each user, such as a home address. An advocacy message is sent to a user through a first communication network, such as by sending an advocacy message associated with an e-mail message. The advocacy message may include a portion that lets the user generate an indication, such as by clicking on a portion of a computer screen. When an indication is received, a response message is sent to the representative associated with the user. The response message includes information about the user, such as the user's name and home address, and may be sent at a pre-determined time along with response messages from other users. The response message may be an e-mail message, a facsimile message, a printed letter or a telephone call.Type: GrantFiled: January 14, 1999Date of Patent: October 30, 2001Assignee: Juno Online Services, Inc.Inventors: David E.
