The parallel grid architecture lets you run a job on multiple engines. A typical multiengine job contains multiple projects with few or no dependencies between them. Thus, projects can be executed on multiple engines at the same time after you have installed the multiple engines, and registered them for a special repository.
Sybase IQ InfoPrimer Server uses User Datagram Protocol (UDP) broadcasts to inform other servers about urgent events, such as starting and stopping, as well as system failure or crash. The default port for communication is 5124, which should not be in use or blocked by a firewall. All other communication between servers is done over TCP/IP on the same port.
When executing a multiengine job from that repository, all projects are executed on those engines.
During execution, the job uses the registered engines to distribute the projects.
