The global standard for high-impact debugging

When each hour of machine time is measured in thousands of dollars, fixing bugs at all scales becomes an urgent priority:

“ 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

Research consistently shows 50% of programming time is spent debugging, and that debugging best practices and tools reduce this by 25%. Allinea's combined package of expert-led training packages and world-class debugger work together to increase programmer efficiency whatever their experience.

Allinea DDT sparklines

Over the past decade our customers have praised Allinea DDT's innovative, intuitive GUI - features like zero-click variable comparisons and powerful array visualizations quickly become second-nature.

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