Abstract:

A distributed computing system comprises a primary server having a primary virtual shared memory and a back-up server having a back-up virtual shared memory. The primary server periodically provides a state table to the back-up server in order to synchronize the virtual shared memory and the back-up virtual shared memory. A plurality of client computer resources are coupled to the primary server and the back-up server through a network architecture. The client computer resources further comprise plural worker processes each adapted to independently perform an operation on a data object disposed within the primary virtual shared memory without a predetermined assignment between the worker process and the data object. Upon an unavailability of either the primary server or the back-up server, the worker process performs the operation on the corresponding data object disposed within the back-up virtual shared memory. The client computer resources further comprise plural input/output (I/O) ports adapted to receive incoming data packets and transmit outgoing data packets.
