DDT’s scalability and ease of use provide cost-efficiency and rapid ROI across all NEC platforms. Allinea Software, a leading provider of innovative products for large-scale scalar and parallel high performance computing applications, today announced that it has ported its popular Distributed Debugging Tool (DDT) to NEC SX Series vector supercomputers. For several years, NEC had been using DDT on Linux and other systems with much success, but the debugging tool was not available for the powerful SX vector supercomputers. Allinea worked closely with NEC and the High Performance Computing Centre (HLRS) in Stuttgart, a leading research facility that uses the SX-8 for complex engineering simulations, to port DDT for the SX series, enabling access to this state-of-the-art parallel debugger for every NEC platform. “Vector supercomputers—such as the SX series—require a powerful and scalable debugging tool like DDT to ensure that developers can fix problems with their complex large-scale calculations rapidly,” said David Lecomber, CTO of Allinea Software. “By porting DDT to the SX Series, now NEC’s current and new customers can use the same parallel debugger on every platform —from high end to low end.” DDT is recognized as the industry’s most technically advanced tool for debugging parallel applications, with a graphical interface acclaimed for its ease-of-use and short learning curve. “The SX-8 we use at HLRS provides multiple teraflops performance over a range of complex engineering applications,” said Dr. Michael Resch, Director of the HLRS and Chairman of the NEC User Group. “As such, we require a debugging tool that is not only state-of-the-art, but is easy for programmers to learn and use. We were impressed with DDT’s performance on Linux and other platforms. Porting DDT to the SX series now provides programmers with total scalability in that they can use the market’s leading debugging program, with the same look, feel and functionality, for all of NEC’s systems The result is continual high computing performance with greater cost efficiency and a rapid return on investment.” DDT can be purchased online at the Allinea website (www.allinea.com) and is compatible with other operating systems such as AIX, Linux and Solaris on x86, AMD64, EM64T, IA64, Power, Cell and UltraSPARC processors. Allinea Software will be exhibiting at the International Supercomputing Conference (ISC2008) in Dresden, Germany from June 17-20, 2008.
