Arm DDT is a powerful, easy-to-use graphical debugger. It provides a complete solution for finding and fixing problems on a single thread or across hundreds of thousands of threads. You can use Arm DDT to debug OpenMP, parallel (MPI) software, heterogeneous software such as that written to use GPUs, hybrid codes mixing paradigms such as MPI + OpenMP, or MPI + CUDA, and multi-process software of any form, including client-server applications.

Arm DDT is cross-platform and can run on your own laptop, the latest supercomputer, and tomorrow's upcoming architectures. It supports 64-bit Armv8, x86_64, knl, and ppc64le.
