Title: Starting LispWorks in multiprocessing mode

ID: 16009


Product: LispWorks
Version: All
OS: All

Description:
This article applies to UNIX LispWorks as well as Windows and Linux LispWorks images which have been saved with the :environment nil option to save-image. By default, Windows and Linux LispWorks images start the programming environment in multiprocessing mode.

Question: The documentation for mp:initialize-multiprocessing states that the function does not return until multiprocessing terminates. What is the best way to start multiprocessing when LispWorks is started?

Answer: There are three ways, all of which will start multiprocessing after doing the usual initializations:

1. Use the -multiprocessing command-line argument
2. Save the image to start with multiprocessing by doing
  (save-image "mp-lispworks"
              :restart-function 'mp:initialize-multiprocessing)

3. Use delivery to create the executable and pass the options
  :multiprocessing t
The delivery function will be called automatically in a new process. See the Delivery User Guide for more details.

In all cases, mp:*initial-processes* can be used to control which processes are created on startup.
