The Atom Queue operation describes how the Atom Message Queue will function.
The Maximum Concurrent Executions setting should be set conservatively as this this value is the atom setting for the number of concurrent AtomQueue listener processes. Setting this value to send hundreds of messages to the queue will result in hundreds of AtomSphere processes to be created and executed.


It is important to test this setting by starting with a small value and slowly increment and continue to test. Setting this value too high will consume additional messaging resources and may cause the Atom to run out of memory and crash. Once the Atom is restarted it will continue to create the number of concurrent processes until it is able to do so.


Please Note: For Molecules and Clouds, this limit is per node in a cluster.


Please refer to our Reference Guide for additional details for the Atom Queue Operation.
