Process Host

Process hosts manage Lua process execution using a work-stealing scheduler.

Each host schedules processes independently. Load is not distributed between hosts automatically.

Entry Kind

Kind	Description
`process.host`	Process execution host with scheduler

Configuration

- name: main_host
  kind: process.host
  host:
    workers: 8
    queue_size: 1024
    local_queue_size: 256
  lifecycle:
    auto_start: true

Field	Type	Default	Description
`workers`	int	NumCPU	Worker goroutines
`queue_size`	int	1024	Global queue capacity
`local_queue_size`	int	256	Per-worker local deque size

Scheduler

The scheduler uses work-stealing: each worker has a local deque, and idle workers steal from the global queue or other workers. This balances load automatically.

Workers execute processes concurrently
Global queue holds pending processes when all workers are busy
Local queues reduce contention by keeping work close to workers

Process Types

Process hosts execute entries of these kinds:

Kind	Description
`lua.process`	Source-based Lua process
`lua.process.bytecode`	Precompiled Lua bytecode

Additional process kinds are planned for future releases.

Processes run independently with their own context, communicate via messages, and are supervised for fault tolerance.
