Arm DDT is the number one server and HPC debugger in research, industry, and academia for software engineers and scientists developing C++, C, Fortran parallel and threaded applications on CPUs, GPUs, Intel and Arm. Arm DDT is trusted as a powerful tool for automatic detection of memory bugs and divergent behavior to achieve lightning-fast performance at all scales.
Arm DDT Makes Debugging Faster
- Cross-platform for multiple server and HPC architectures
- Has market leading memory debugging
- Outstanding C++ debugging support
- Complete Fortran debugging support
- Has an offline mode for debugging non-interactively
- Handles and visualizes huge data sets
CGG
Arm DDT is a powerful parallel debugger, available standalone or as part of the Arm Forge debug and profile suite. Its intuitive graphical interface provides automatic detection of memory bugs and divergent behavior at all scales.
Arm DDT’s powerful intuitive GUI sets the standard for multi-process and multi-threaded debugging. Zero-click variable comparisons, built-in memory debugging and powerful array visualizations simplify the complexity of debugging software - whether on the desktop or today's increasingly parallel processors, clusters and supercomputers.
Moving to a new architecture or system is challenging enough without learning a new toolchain at the same time. Arm DDT runs everywhere - on your own laptop, the latest supercomputer and tomorrow's upcoming architectures. It supports Arm 64-bit, Intel Xeon, Intel Xeon Phi, NVIDIA CUDA, and OpenPOWER.
Maximize the results with on-site and web-based training courses from the experts in parallel debugging. A wide range of training materials and direct email access to our support team ensures you get the most out of your hardware and software for years to come.
Helping to Improve the Pace and Precision of Forecasting
Being one of the very few parallel debuggers, Arm DDT is able to debug code for weather forecasting and climate modelling. Arm DDT lowers the risk of major changes during code development – by working with software version control systems to automatically log values of variables across all processes at each changed section of code.
