Summary
The ‘Control-Program’ of VM370 acts as a supervisor on the real hardware. It manges the resources of a single system/360 or /370 computer so that multiple computing systems (virtual machines) appear to exist. The resourecs that are distributed to the different virtual machines are virtual cpu-timef virtual memory, virtual channels and devices.
Alternatively SIM-BS1000 is embedded as part of the BS2000 operating system. The distribution of resources and the treatment of the interrupts are largely controlled by BS2000. One or more virtual machines, i.e. the functional simulation of 4004 hardware and a 4004 operating system like BS1000, run as normal tasks in the BS2000 environment.
