If this is not the case, press the ''Change'' button next to the ''Implementation:'' string, and select the correct option from the drop-down menu.

IMPORTANT: The current versions of DDT and OpenMPI have a compatibility issue which breaks the important feature of DDT - displaying message queues (available from the "Tools" drop down menu). There is a workaround: before running DDT, you have to execute the following command: | |||
