A system, method and computer program product to synchronize processing across multiple lanes. In a system, a synchronizing interface network controller (SINC) communicates with a plurality of processors. Each processor executes an application having thread(s) of operation. Each processor notifies the SINC when a specific thread is ready to perform a respective operation. The SINC releases the processors to perform the respective operation upon being notified by all processors that the specific thread is ready to perform the respective operation. Each processor is configured to monitor for the release of the processors and to also determine whether sufficient time remains within a time window to perform the respective operation. If insufficient time remains, a processor notifies the SINC that the specific thread is no longer ready to perform the respective operation. If the processors are released by the SINC while sufficient time remains, each processor performs the respective operation.

System and method for synchronizing processing between a plurality of processors

A method for synchronizing messages between processors is provided. The method comprising receiving, by a first external device, inbound messages for applications running redundantly in high integrity mode on two or more multi-core processors. The inbound messages are synchronously copied to the multi-core processors. The multi-core processors send outbound messages to respective alignment queues in the first external device or a second external device, wherein the outbound messages contain calculation results from the inbound messages. The first or second external device compares the alignment queues. Matched outbound messages in the alignment queues are sent to a network or data bus. Any unmatched outbound messages in the alignment queues are discarded.

Message synchronization system

A method for monitoring data integrity on a network includes reading error data from an interface associated with a particular link of the network in response to error data being present in a message received on the particular link. The method also includes creating a report message including the error data and transmitting the report message to a network monitoring algorithm operable on a processor circuit. The network monitoring algorithm is configured to determine a data integrity of the particular link based on the error data.
