Massive performance revolution for all parallel software developers

WARWICK, England, April 27 -- Allinea Software -- recognised as the leading supplier of software development tools for high performance computing (HPC) -- has released the first industrial strength debugger for parallel computing on systems with hundreds of thousands of processor cores that deliver petaflops performance.

This totally new version of Allinea DDT dramatically shortens debugging time and improves efficiency for small and mid scale users -- however the new technology it incorporates makes debugging possible for the first time for users of the world's largest supercomputers as they approach petascale performance.

Support to handle the most complex codes

Allinea DDT 3.0 is based on a brand new tree-based architecture that provides a logarithmic improvement in scalability and response time. The enhanced user interface also makes it easy to scale from debugging at small to very large scales. Smaller system users can thus now benefit from the powerful new features in Allinea DDT, such as Smart Highlighting, enhanced C++ features and new support for the most complex and demanding codes.

Large scale users will now be able to manage huge programs which can run on very large systems. All these features together offer users dramatically improved debugging performance.

Massive performance revolution for users

Mike Fish, CEO of Allinea Software, explains: "The release of Allinea DDT 3.0 marks a massive performance revolution for users, making possible tasks that were previously unattainable. As systems become ever larger, huge amounts of debug data are generated which -- with conventional tool architectures -- are almost impossible to present intelligibly to the user and create unacceptably long response times. Allinea's partnerships with the largest and most demanding supercomputer centres around the world gives us a unique insight on how to deliver the performance needed for Petascale debugging -- as evidenced by the logarithmic degradation in response time demonstrated at Petascale on Cray XT5 super computers -- making Allinea DDT the most user-friendly product for all types of user.

New features and enhancements

Allinea DDT 3.0 offers users a significant number of new improved features, including:

• New Petascale Architecture provides lightning response times for all users.
• "Smart Highlighting" automatically highlights comparisons across processes: variables, changes in data, etc.
• Improved C++ STL features: display and response time.
• Combine and graphically display array components from multiple processes.
• Tracepoints -- intelligent logging and merging of variable history during execution.

Chosen by the elite of supercomputing

Allinea DDT was recently selected as the parallel debugger for one of the world's first Cray XE6 installations. The debugger was chosen for this latest generation super computer following a competitive tender by the US National Energy Research Scientific Computing Center (NERSC), the flagship scientific computing facility for the Office of Science at the US Department of Energy. One of the largest facilities in the world devoted to providing computational resources and expertise for basic scientific research, NERSC is a world leader in accelerating scientific discovery through computation.
