Debugging

Debugging GITR with cuda-gdb:

To debug GITR on NVIDIA devices with CUDA turned on, you can use cuda-gdb.

1. Set the CMAKE_BUILD_TYPE to "Debug" instead of "Release"
2. Build using the build.sh script
3. Go to the folder you'd like to run and execute cuda-gdb ~/path/to/GITR
4. Set a breakpoint at a line of interest break particle_diagnostics.cpp:34
5. Run the debugger by hitting r
6. Once the debugger stops at the line of interest you can print and advance as necessary

• to print particle information, like the variable x for a particle from the Particles class , you can use print particlesPointer->x.data_[indx]
• to advance you can use s for step
• all of these commands correspond to gdb documentation that can be found online
