User Program And Operating System Interface In A Multithreaded Environment
US Patent:
6952827, Oct 4, 2005
Filed:
Nov 13, 1998
Appl. No.:
09/192205
Inventors:
Gail A. Alverson - Seattle WA, US
Susan L. Coatney - Federal Way WA, US

Assignee:
Cray Inc. - Seattle WA
International Classification:
G06F009/46
G06F015/16
G06F015/16
US Classification:
718104, 718100, 718102, 718107, 709225, 709226, 709229, 709203
Abstract:
A method and system that prepares a task for being swapped out from processor utilization that is executing on a computer with multiple processors that each support multiple streams. The task has one or more teams of threads, where each team represents threads executing on a single processor. The task designates, for each stream, one stream that is executing a thread as a team master stream. The task designates one stream that is executing a thread as a task master stream. For each team master stream, the task notifies the operating system that the team is ready to be swapped out when each other thread of the team has saved its state and has quit its stream. Finally, for the task master stream, the task notifies the operating system that the task is ready to be swapped when it has saved its state and each of the other teams have notified the operating system that that team is ready to be swapped out.
Techniques For Reducing The Rate Of Instruction Issuance
US Patent:
7020767, Mar 28, 2006
Filed:
Feb 23, 2001
Appl. No.:

Assignee:
Cray Inc. - Seattle WA
International Classification:
G06F 9/44
US Classification:
712227
Abstract:
A method and system in a multithreaded processor for processing events without interrupt notifications. In one aspect of the present invention, an operating system creates a thread to execute on a stream of the processor. During execution of the thread, the thread executes a loop that determines whether an event has occurred and, in response to determining whether an event has occurred, assigns a different thread to process the event so that multiple events can be processed in parallel and so that interrupts are not needed to signal that the event has occurred. Another aspect of the present invention provides a method and system for processing asynchronously occurring events without interrupt notifications. To achieve this processing, a first thread is executed to generate a notification that the event has occurred upon receipt of the asynchronously occurring event. A second thread is also executed that loops determining whether a notification has been generated and, in response to determining that a notification has been generated, performing the processing necessary for the event.
