Hi Mathieu

 Thank you very much for confirming. 

umppc*****.dll (s) are part of an Endpoint Protection Program 

It appears this Endpoint Protection Program causes isues with MPI (Parallel processing).

We have reports that it causes problem such as slowdowns or crashes in the Ansys and Fluent parallel solvers. 

You may want to report this issue to your IT department.
