DDT* Debugger

You can debug MPI applications using DDT* debugger. Intel does not provide support for this debugger. You should obtain the support from Allinea*. According to the DDT User Guide at http://www.allinea.com/products/ddt-support/, you can use the –tv option to run DDT with certain TotalView* variables set beforehand.

$ export TOTALVIEW=DDT_INSTALLATION_PATH/bin/ddt-debugger-mps

$ mpirun -np 4 -tv ./your_app

If you have problems with the DDT debugger, see DDT documentation for help.
