There is a business with about 100 computers used by employees, and one high-powered server. It's called a "distributed system" by the system architect. It uses Distributed Shared Memory (DSM). There's also middleware, and the server is hosting Virtual Machines (VMs) which are running the applications that the employees see.
The question is: does the DSM come from physical memory that the server is sharing, creating virtual shared memory, or does the memory come from those 100 computers (or both)? Aside from the possible speculation here, could portions of the physical memories of the 100 computers even be utilized as DSM in this setup?
(Please note that distributed systems and shared memory are course topics in data science programs. That's why I'm posting this here. Data science isn't just data mining - it's a lot more. The nuts and bolts behind doing it are included.)
