Run ipc command in multi-thread

Martinsh

How to run ipc command in multi-thread?

For example, 100 tasks will run on 5 threads.  At begining, the first 5 tasks are arranged on 5 threads. When one of the 5 tasks is completed, next task start automaticlly. There are always 5 tasks runing until no taskes left.

  • Hi Martin,

    Not sure you could really call that multi-threading but here is a SKILL++ function that should do the job you're asking for :

    (inScheme
  (defun ipc_run_parallel (commands threads "lx")
    "Run COMMANDS in several parallel THREADS"
    (defun run_next_command nil
      (let ((command (pop commands)))
        (when command
          (ipcBeginProcess command ""
            (lambda (_pid _data)   nil)
            (lambda (_pid _data)   nil)
            ;; Start next thread when the current one is finished
            (lambda (_pid _status) (run_next_command))
            ))))
    ;; Start several threads in parallel
    (for i 1 threads (run_next_command))
    ))

    You can use it like :

    (ipc_run_parallel '("sleep 1" "sleep 2" "sleep 3" "sleep 4") 4)

    Cheers,
