ScreepsOS

Screeps/Serializable Operating System (SOS)

Lightweight generator-based OS.

• desined to be serializable and restorable from plain memory (no RPC or eval calls)
• control flow can be modified by built-in "system calls", which are special objects can be yielded from process loop
• kernel supports generators *run() {} and ordinary run() {} process loop functions
• adjustable scheduler and secure memory management (every process has its own isolated memory)

Implemented SYSCALLs:

SYSCALL	Description
yield new Yield();	allows scheduler to interrupt process to be continue later this tick
yield new Sleep(10);	stops process execution for several ticks
yield new Fork(priority, class);	runs new child process
yield new Inject(pid);	allows to modify child processes memory
yield new Kill();	kills process
yield new Reboot();	finishes current tick execution
yield new Priority(newVal);	requests for new priority value
