Allinea DDT is a commercial C, C++ and Fortran 90 debugger produced by Allinea Software of Warwick, United Kingdom. It is widely used for debugging parallel MPI and threaded (pthread or OpenMP) programs, including those running on clusters of Linux machines. As of June 2015 it is used on 58 of the top 100 supercomputers on the TOP500 list.
It was the first debugger to be able to debug petascale applications - having been used to debug applications running concurrently on 220,000 processes on a Cray XT5 at Oak Ridge National Laboratories. This is possible interactively as the debugger's control tree architecture leads to logarithmic performance for most collective operations. Allinea DDT uses the GNU Debugger as debug engine.
It is part of Allinea Forge - a suite of tools for developing code in high performance computing - which also includes the performance profiler for scalar, multithreaded and parallel codes - Allinea MAP.
