Allinea DDT: The global standard for high-impact debugging on clusters and supercomputers

Research consistently shows 50% of programming time is spent debugging, and that debugging with the best tools and best practices can slash this time.

Allinea's world-leading debugger is the route to being a more effective developer.

Companies and institutions that know the cost of debugging turn to Allinea DDT to solve their problems faster.

When each hour of machine time is measured in thousands of dollars, fixing bugs quickly needs the most capable tools:

My group routinely debugs parallel code at over 100,000 processes using Allinea DDT. No other debugger can even come close to its performance, so obviously it’s a hit with users.
Dr. Richard Graham, Oak Ridge National Laboratory

Allinea DDT - sparklinesDesigned for novice and master alike

Allinea DDT's powerful intuitive GUI defines the standard of multi-process, multi-threaded debugging. Zero-click variable comparisons and powerful array visualizations simplify the complexity of debugging software wriitten to exploit today's increasingly parallel processors.

Expert users often live and breathe on the command-line - so all the benefits of automatic variable comparison and in-process memory debugging are also available in a single command, producing information-rich HTML and text log files for post-mortem analysis.
