To share and thereby reduce processing loads, OpenTP1 can distribute the processing of a service group across multiple processors. This feature is called the Multiserver facility and is described in more detail in 3.4.3 Process control and the Multiserver facility. The Multiserver facility equalizes loads on various processors by passing a service request to any waiting process that can process the same service group.

In OpenTP1, you can define the maximum number of processes that can be executed for each service group.
