Filed:

Apr 1, 2003

Appl. No.:

10/404334

Inventors:

David Blair Gilgen - Raleigh NC, US
Thomas Owings Rowe - Chapel Hill NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 9/46

US Classification:

719318, 718102, 718104

Abstract:

The present invention is an enhanced staged event-driven architecture (SEDA) stage. The enhanced SEDA stage can include an event queue configured to enqueue a plurality of events, an event handler programmed to process events in the event queue, and a thread pool coupled to the event handler. A resource manager further can be coupled to the thread pool and the event queue. Moreover, the resource manager can be programmed to allocate additional threads to the thread pool where a number of events enqueued in the event queue exceeds a threshold value and where all threads in the thread pool are busy.

Abstract:

A high-speed content transformation method, system and apparatus. The method can include inspecting a request for transcoded content to determine input documents required to produce the requested transcoded content; determining whether the input documents have been characterized as standalone, and further determining freshness criteria for the input documents which are determined to have been characterized as standalone; locating in cache storage previously generated transcoded content corresponding to the input documents determined to have been characterized as standalone; and, serving the previously generated transcoded content in response to the request rather than generating the requested transcoded content using the input documents where the previously transcoded content meets the freshness criteria.
