==Group Control System==

GCS - [[VM_VM (operating_systemoperating system)|VM]] Group Control System is a VM guest operating system and an integral component of the discontinued VM/SP (since VM/SP 4), VM/XA SP, VM/ESA and current z/VM IBM System product offerings.

Its purpose is to provide an environment to run some specific [[MVS|OS/MVS]] based applications and networking middleware under VM.

To this end, GCS provides a limited simulation of the OS/MVS APIs. While [[Conversational_Monitor_SystemConversational Monitor System|CMS]] already has OS simulation, it is not extensive enough to run some applications such as [[VTAM]] and VTAM applications.

Specifically, GCS provides OS multitasking support. In order to be able to spread the load over several virtual machines, GCS also implements a notion of group where each group member virtual machine can interact with one another.
