Abstract

An asynchronous distributed computing system with a plurality of computing nodes is provided. One of the computing nodes includes a sequencer service that receives updates from the plurality of computing nodes. The sequencer service maintains or annotates messages added to the global state of the system. Updates to the global state are published to the plurality of computing nodes. Monitoring services on the other computing nodes write the updates into a locally maintained copy of the global state that exists in shared memory on each one of the nodes. Client computer processes on the nodes may then subscribe to have updates “delivered” to the respective client computer processes.
