It is widely used for debugging parallel Message Passing Interface (MPI) and threaded (pthread or OpenMP) programs, including those running on clusters of Linux machines. DebuggerIt is used to find bugs on both small and large clusters, from 1 to 100,000s of processors. It features memory debugging which detect memory leaks, or reading and writing beyond the bounds of arrays. 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.[2][3] This is possible interactively as the debugger's control tree architecture leads to logarithmic performance for most collective operations. Arm DDT uses the GNU Debugger as debug engine. Arm DDT also supports coprocessor architectures such as Intel Xeon Phi coprocessors[4] and NVIDIA CUDA GPUs.[5] It is part of Arm Forge - a suite of tools for developing code in high performance computing - which also includes the performance profiler for scalar, multithreaded and parallel codes - Arm MAP.[6] {{As of|2011}}, 80 percent of the world's top 25 supercomputers on the TOP500 list, use Arm's tools.[7]Notes1. ^{{cite news | title = How Allinea Helps Scientists Run their Applications Faster and Better | url = http://insidehpc.com/2012/12/05/how-allinea-helps-scientists-run-their-applications-faster-and-better/ | publisher = InsideHPC | date = 5 December 2012}} 2. ^{{cite web|url=http://www.olcf.ornl.gov/2010/07/12/upgrade-adds-muscle-to-debugger/|title=Upgrade Adds Muscle to Debugger|publisher=Oak Ridge National Laboratories|accessdate=14 June 2011|archive-url=https://web.archive.org/web/20110623011535/http://www.olcf.ornl.gov/2010/07/12/upgrade-adds-muscle-to-debugger/|archive-date=2011-06-23|dead-url=yes|df=}} 3. ^{{cite news|url=http://cacm.acm.org/news/96797-ornl-allinea-prep-debugging-tool-for-petascale-supercomputers/fulltext|title=ORNL, Allinea Prep Debugging Tool for Petascale Supercomputers|date=30 July 2010|journal=Communications of the ACM}} 4. ^{{cite news|url=http://www.hpcwire.com/hpcwire/2012-11-13/allinea_releases_tools_for_xeon_phi_developers.html|title=Allinea Releases Tools for Xeon Phi Developers|date=13 November 2012|publisher=HPCWire|access-date=2013-01-15|archive-url=https://web.archive.org/web/20130307035519/http://www.hpcwire.com/hpcwire/2012-11-13/allinea_releases_tools_for_xeon_phi_developers.html|archive-date=2013-03-07|dead-url=yes|df=}} 5. ^{{cite web|url=https://developer.nvidia.com/debugging-solutions|title=NVIDIA debugging solutions page}} 6. ^[https://www.arm.com/products/development-tools/server-and-hpc/forge Arm Forge] 7. ^{{cite news |title = Allinea Selected as a Red Herring Top 100 Europe Technology Company |url = http://www.hpcwire.com/hpcwire/2011-06-01/allinea_selected_as_a_red_herring_top_100_europe_technology_company.html |publisher = Tabor Communications |work = HPCwire |date = 2011-06-01 |accessdate = 2013-02-07 |archive-url = https://web.archive.org/web/20120314112744/http://www.hpcwire.com/hpcwire/2011-06-01/allinea_selected_as_a_red_herring_top_100_europe_technology_company.html |archive-date = 2012-03-14 |dead-url = yes |df = }} External links
