A distributed processing system delegates the allocation and control of computing work units to agent applications running on computing resources including multi-processor and multi-core systems. The distributed processing system includes at least one agent associated with at least one computing resource. The distributed processing system creates work units corresponding with execution phases of applications. Work units can be associated with concurrency data that specifies how applications are executed on multiple processors and / or processor cores. The agent collects information about its associated computing resources and requests work units from the server using this information and the concurrency data. An agent can monitor the performance of executing work units to better select subsequent work units. The distributed processing system may also be implemented within a single computing resource to improve processor core utilization of applications. Additional computing resources can augment the single computing resource and execute pending work units at any time.

Described herein is a method and system for distributing whole and fragmented requests and responses across a multi-core system. Each core executes a packet engine that further processes data packets and data packet fragments allocated to that core. A flow distributor executing within the multi-core system forwards client requests to a packet engine on a core that is selected based on a value generated when a hash is applied to a tuple comprising a client IP address, a client port, a server IP address and a server port identified in the request. The packet engine maintains each element of the tuple and forwards the request to the selected core. The packet engine can also process data packet fragments by assembling the fragments prior to transmitting them to the selected core, or by transmitting the data packet fragments to the selected core.

Value based tokens are generated for inclusion on a data carrier which may be applied to a cheque or similar document. The tokens are generated by a core system, which communicates with application specific wrappers. The wrappers supply token parameters to the core that are specific to the application and the core generates the tokens, and stores them for later authentication. The core then encodes the tokens onto a data carrier under the control of the wrapper and distributes the tokens under the control of the wrapper. The tokens are encoded onto the cheque when it is printed. When a cheque is presented for authentication, for example by at a bank, the signed cheque is imaged and the token retrieved from the encoded data carrier. It is passed back to the core by the wrapper for authentication of its identification number and other parameters. The image may be sealed by a further data carrier which may be printed on the cheque or added to the electronic image. The further data carrier may include a separate token or have a token which is related to the first token. Where the data carrier is applied to the electronic image it may replace the first data carrier. The data stored on the carrier references cheque information stored at a database which is compared with cheque information retrieved from the cheque.
