+:: Make sure the MPI implementation is the default OpenMPI in the DDT/MAP application window, before pressing the ''Run'' button. 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. Also, specify the desired number of cpu cores in this window.

 . When done, exit the shell to terminate the allocation.
+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:
+ $ export OMPI_MCA_pml=ob1
+Be aware that the above workaround can make your MPI code run slower, so only use this trick when debugging.
