For those of my age (early 30’s), MVS is an abbreviation for Multiple Virtual Storage, an operating system for IBM mainframe computers such as the System/360 (the chief architect of this computer was Gene Amdahl, which will be familiar to those who have dabbled in parallel programming)

The author of the tweet also has a Youtube channel with the following description:
