https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes<p>In Ivy I can parallelize processes (and too User Dialog logic) with a Split element and synchronize them again with the Join element. Does this run in multiple threads?</p>enWed, 29 Mar 2017 20:39:05 -0400https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes#2550<p>Split and Join are also available in the logic of Html Dialogs. They work there the same way like in the "Business Process", "Callable Sub Process" and "Web Service Process".</p>Alex SuterWed, 29 Mar 2017 20:39:05 -0400https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes#2550https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes#2548<p>hi <a href="http://answers.axonivy.com/users/71/kaspar-von-gunten"><a href="http://answers.axonivy.com/users/71/kaspar-von-gunten">@Kaspar von</a></a> G... SpitJoin just available on Start/Callable process sub. So in case i want to have parallel thread inside HtmlUserDialog, i need to handle by myself (Runnable/Thread) right?</p>trungdvWed, 29 Mar 2017 08:48:04 -0400https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes#2548https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes/330<p>No, in general all the process pathes started with a Split element are executed in the same thread. It's only pseudo-parallel. </p> <p>But there exceptions, all the elements that potentially communicate with third-party systems do run in their own thread, e.g. the PI, DB call or web service call elements. So if you combine Split and Join with e.g. PI's (but not with Script elements) you have real parallel execution. </p>Kaspar von GuntenMon, 08 Feb 2010 05:20:34 -0500https://answers.axonivy.com/questions/329/multi-threading-in-ivy-processes/330
