| Allinea DDT helps developers fix bugs quickly - from the desktop to the largest supercomputer. The most scalable parallel debugger for debugging MPI and multi-threaded codes, DDT leads the world in performance and usability. |
| ||||||||||||
Usage
DDT is available through modules
module load debugger/forge
Note: Do not forget to compile your application with debugging info (-g option)
Examples
starting the application from inside DDT
Get an interactive job and set up the environment within
module load debugger/forge
module load mpi/openmpi
module load mpi/openmpi
Compile your application
mpicc -g your_app.c -o your_app
Start DDT:
ddt your_app
Select the right MPI implementation in the options and run your program.
Hazel Hen special
To debug a program with ddt on Hazel Hen you have to use the Reverse Connection feature. Therefore first launch ddt on a login node:
module load forge
ddt
ddt
Load the forge module in your job script or interactive job and modify your aprun command line therein
module load forge
ddt --connect aprun ...
ddt --connect aprun ...
