US 7257582

US Patent 7257582, titled "Load balancing with shared data", was filed on February 27, 2003, and issued on August 14, 2007. The sole inventor is Michael Rothschild. The current assignee of record is Intellectual Ventures I LLC.

Abstract:
The patent describes a method for a computer-executable process where a preexisting input file is logically subdivided, without initial reading, into multiple partitions. These partitions are then distributed to a plurality of processors, which carry out respective subtasks, including reading and processing their assigned partitions. This method enables the distribution of processing large amounts of data across multiple cooperating processors, ensuring that the load on each processor is proportional to its capacity, thereby optimizing efficiency.

Independent Claims Overview:

Independent Claim 1:
This claim describes a method for performing a computer process on an input file by breaking it down into smaller, manageable parts. First, the system automatically determines how to divide the input file's records into multiple logical partitions. Descriptions of these partitions are then sent to various subtask processors. Simultaneously, at least some of these processors begin executing their assigned subtasks, each reading and processing one partition to produce a specific output. Afterward, this process repeats, with available processors taking on new, unassigned partitions on a first-come, first-served basis. Finally, all the individual subtask outputs are combined to create a single, comprehensive output that reflects the overall processing.
