operating systems

Basic idea

OS topics relevant to distributed systems: memory and address spaces, processes and threads, IPC, and how these are extended (or not) across machine boundaries.

Key facts

• Networked OS: each host autonomous, user does explicit network ops.
• Distributed OS: location transparency — the OS hides the network from the user.
• Core primitives: processes, threads, address spaces, file descriptors, IPC.
