Abstract:

A method and apparatus for parallel processing of remote procedure call (RPC) requests from clients includes placing the remote procedure call requests in a queue and storing them in a memory. A response is immediately returned to the client indicating receipt of the processing request. The RPC requests are retrieved from the queue and processed in parallel. Notification of the completed processing is provided to a notification client. In the event of a server fault or system failure, the processing requests are retrieved from the memory upon system restoration, and replaced into the queue in the order they were received by the server.
