US Patent:

20050068975, Mar 31, 2005

Filed:

Sep 30, 2003

Appl. No.:

10/675363

Inventors:

Pierre Colin - Torrance CA, US
Martin Watson - Santa Monica CA, US

International Classification:

H04L012/54

US Classification:

370428000, 370235000, 714748000

Abstract:

A method, computer program, and system are disclosed for transferring data. Data packages are transmitted from a plurality of data sources to a first gateway. The data packages are transmitted from the first gateway to a second gateway. The data packages are transmitted from the second gateway to a plurality of data destinations. Acknowledgement messages are transmitted from the data destinations to the second gateway. Pause messages are generated at the second gateway based at least in part on the reception of the acknowledgement messages by the second gateway. The pause messages are transmitted from the second gateway to the first gateway.

International Classification:

G06F 1516

US Classification:

364200

Abstract:

A system using a sorting network to intercouple multiple processors so as to distribute priority messages to all processors is characterized by semaphore means accessible to both the local processors and the global resource via the network. Transaction numbers identifying tasks are employed in the messages, and interfaces at each processor are locally controlled to establish transaction number related indications of the current status of each task being undertaken at the associated processor. A single query to all processors via the network elicits a prioritized response that denotes the global status as to that task. The transaction numbers also are used as global commands and local controls for the flow of messages. A destination selection system based on words in the messages is used as the basis for local acceptance or rejection of messages. This arrangement together with the transaction number system provides great flexibility as to intercommunication and control.

US Patent:

59601817, Sep 28, 1999

Filed:

Dec 22, 1995

Appl. No.:

8/577956

Inventors:

M. Yahya Sanadidi - Santa Monica CA
Martin Cameron Watson - Los Angeles CA
Richard R. Muntz - Pacific Palisades CA

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06F 9455

US Classification:

395500

Abstract:

A computer performance modeling system is provided. The modeling system includes a first and a second submodel which simulate system operations of a particular system component in minute and simple detail, respectively. A performance analysis mechanism is operatively coupled to the first and the second submodel to execute a simulation of the particular system component using the first and the second submodel. The performance analysis mechanism has a switching device for switching between the first and the second submodel during the simulation at a predetermined point in the execution of the simulation. In an alternative embodiment, the second submodel derives a specific behavior from simulation statistics collected by the first submodel. Also, the performance analysis mechanism executes a simulation of a system model having several of the particular system components by using a plurality of the first and the second submodels. A method for modeling computer performance also is provided.
