Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 9/46
G06F 1/00
US Classification:
718102, 718104, 713330
Abstract:
An apparatus and method for making fractional assignments of processing elements to processing nodes for stream-based applications in a distributed computer system includes determining an amount of processing power to give to each processing element. Based on a list of acceptable processing nodes, a determination of fractions of which processing nodes will work on each processing element is made. To update allocations of the amount of processing power and the fractions, the process is repeated.

US Classification:
706 46
Abstract:
A method is provided for generating a resource function estimate of resource usage by an instance of a processing element configured to consume zero or more input data streams in a stream processing system having a set of available resources that comprises receiving at least one specified performance metric for the zero or more input data streams and a processing power of the set of available resources, wherein one specified performance metric is stream rate; generating a multi-part signature of executable-specific information for the processing element and a multi-part signature of context-specific information for the instance; accessing a database of resource functions to identify a static resource function corresponding to the executable-specific information and a context-dependent resource function corresponding to the context-specific information; combining the static resource function and the context-dependent resource function to form a composite resource function for the instance; and applying the resource function to the at least one specified performance metric and the processing power to generate the resource function estimate of the at least one specified performance metric for processing by the instance.

David Tao - Glen Burnie MD, US
Joel Leonard Wolf - Katonah NY, US
Laura Wynter - Chappaqua NY, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 3/12

US Classification:
358 115, 718102, 718103, 718104, 718105
Abstract:
A method of choosing jobs to run in a stream based distributed computer system includes determining jobs to be run in a distributed stream-oriented system by deciding a priority threshold above which jobs will be accepted, below which jobs will be rejected. Overall importance is maximized relative to the priority threshold based on importance values assigned to all jobs. System constraints are applied to ensure jobs meet set criteria.

Methods And Systems For Assigning Non-Continual Jobs To Candidate Processing Nodes In A Stream-Oriented Computer System

US Patent:
8458720, Jun 4, 2013
Filed:
Aug 17, 2007
Appl. No.:
11/840556
Inventors:
Nikhil Bansal - Yorktown Heights NY, US
Kirsten Weale Hildrum - Hawthorne NY, US
Deepak Rajan - Fishkill NY, US
Joel Leonard Wolf - Katonah NY, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 9/46
US Classification:
718107, 718103, 718104
Abstract:
A system and method for choosing non-continual jobs to run in a stream-based distributed computer system includes determining a total amount of resources to be consumed by non-continual jobs.
