Allinea DDT, is a commercial debugger produced by Allinea Software of Warwick, United Kingdom, primarily for debugging parallel MPI or OpenMP programs, including those running on clusters of Linux machines, but also used by many for scalar code in C, C++ and Fortran 90. As of November 2013 it is used on 46 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 Software is a founding member of the European Technology Platform for HPC, which consists of vendors and research centers. Its mission is to improve European HPC capabilities.
Allinea Software also develops the MPI performance profiler - Allinea MAP.
