Abstract: A hive of computing engines, typically including clients, request handlers, process handlers, and task handlers, is used to process of a processing job in order to determine a processing result. A client assigns a processing job to a request handler, which assigns the processing job to a processing handler, which typically assigns one or more tasks of the processing job to one or more task handlers. One implementation uses one or more volunteer operations to identify the request handler, the process handler, and/or one or more task handlers. One implementation updates the request handler and/or the process handler with state information related to the partial processing of the processing job such that the completion of the processing job can be assigned to other process and/or task handlers, such as, but not limited to, in response to a detected error condition.

Abstract: A hive of computing engines, typically including request handlers and process handlers, is used to process information. One implementation includes a request region including multiple request handlers and multiple processing regions, each typically including multiple process handlers. Each request handler is configured to respond to a client service request of a processing job, and if identified to handle the processing job: to query one or more of the processing regions to identify and assign a particular process handler to service the processing job, and to receive a processing result from the particular process handler. Each of the process handlers is configured to respond to such a query, and if identified as the particular process handler: to service the processing job, to process the processing job, to update said identified request handler with state information pertaining to partial processing of said processing job, and to communicate the processing result to the identified request handler.
