另外,关于DMU模块cache多进程是用来做什么的呢?
1.Product Visualization。
Multi process visualization mode with local cache: when the Cache is activated. You can choose the creation of Cache files in multi process (DMU context).
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.

You must have activated the variable Multi process visualization mode with local cache in the Product Structure options. See Product Visualization.
The Multiprocess settings page concerns the following settings categories:
Multiprocess parameters
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.
