Making the case for OpenVMS as a real-time platform is a tough sell. I have a Raspberry Pi I use for data collection and make that data available on the LAN via NFS. A VMS system aggregates the data for report generation (associating it with weather data from the internet.

The later generations of Pi are overkill for what I'm doing, the 2B+ was ideal.

A tough sell indeed. On my x86_64 system, 'SHOW SYSTEM /SCHEDULING_CLASS' displays nothing at all...

[imiller]

"The class scheduler gives you the ability to limit the amount of CPU time that a system's users may
receive by placing the users into scheduling classes. Each class is assigned a percentage of the overall
system's CPU time."

There are no scheduling classes until you create some.

See VSI OpenVMS Programming Concepts Manual, Volume I section 4.5
