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 is used to find bugs on both small and large clusters, from 1 to 1,000s of processors. It is the first debugger to be able to debug a Petascale system - having debugged 220,000 processes, over 2 Petaflops, on a Cray XT5 at Oak Ridge National Laboratories.
The debugger has logarithmic performance for most collective debugging operations, due to using a tree architecture across the machine network to control the many single-process debuggers. This architecture enables operations to be measured in milliseconds at full scale.
Allinea Software's products are used globally by a wide range of companies and institutions to solve real world grand challenges. For example, Allinea DDT is used by:
- Titan (supercomputer) at Oak Ridge National Laboratory to support ground-breaking research.
- Blue Waters at The University of Illinois - Allinea Software’s tools will enable scientists to exploit Blue Waters’ full potential by resolving software bugs at the full scale of the machine – both for CPU and hybrid CPU-GPU codes.
- Swiss National Supercomputing Centre's Cray XK7 machine. With over 50,000 CPU cores and around 200 powerful NVIDIA Tesla X2090 GPU cards on site, developers at CSCS are aiming to achieve significant scientific breakthroughs with their applications.
- Atomic Weapons Establishment, who plays a crucial role in the defense of the United Kingdom, by providing and maintaining the warheads for the country’s nuclear deterrent, Trident.
- The Pawsey Centre supercomputers in Australia, which support research into geosciences, astronomy, nanotechnology and biosciences and two major radio telescope projects – the Australian Square Kilometre Array Pathfinder (ASKAP) and the Murchison Widefield Array (MWA), processing their data in real time.
