Multi-processes concern the CATDMUUtility processes that are created as child processes for the tessellation of documents when performing a File -> Open of a CATProduct or when running the CATDMUUtility batch process using the -mp option. This new feature enables the management of possible coredumps and / or looping problems during tessellation such that the impact is localized to the specific document that cannot be tessellated; the state of a V5 session will no longer be impacted by these problems and a CATDMUUtility batch process will run to conclusion. A log file indicates which documents could not be tessellated.

The Multiprocess settings page concerns the following settings categories:

The Multiprocess parameters enable you to customize:

  • The maximum number of child processes that will be launched.
  • The maximum amount of time a process will be allowed to loop before it is killed.
  • The path of the log file that will report the success or non-success of each tessellation concerned with the opening of a CATProduct.

Maximum son processes

ascenari.gif (1376 bytes) The number of child processes is limited to 1.  
  In the Maximum son processes text-entry field, enter the maximum number of child CATDMUUtility processes to be used during tessellation.

By default, this option is valuated to 2.


Timeout (minutes)

  In the Timeout (minutes) text-entry field, enter the maximum time that a single tessellation process will be allowed to loop before being aborted.

By default, this option is valuated to 60.
