Supports versions 3.1 and 3.2 of the NVIDIA Toolkit; Beta tested

Allinea Software - www.allinea.com, the leading supplier of software development tools for high performance computing (HPC), has announced the availability of Allinea DDT 2.6.1, which supports versions 3.1 and 3.2 of the NVIDIA CUDA Toolkit and has been beta tested for several weeks.

This latest version adds support for multiple GPU devices within the same node, in addition to the existing capabilities for debugging clusters of GPU systems. It also supports the latest hardware, with some of the newer features such as device function call and stepping into and out of nested functions on the Fermi hardware now possible.

DDT's scalable debugging interface includes many components that simplify the task of debugging multiple kernels and multiple processes – such as the parallel stack view which intuitively consolidates the display of host and GPU thread stacks, allowing the user to identify rogue threads or processes quickly.

Sanford Russell, general manger, GPU computing software at NVIDIA, explains: "As the market for GPU computing continues to accelerate, we are seeing increasing demand for cluster-class debuggers. Allinea DDT 2.6.1 responds to this need and delivers an innovative solution for developers looking to harness the massively parallel architecture of GPUs in their applications."

Mike Fish, Chief Executive Officer (CEO), explains: "As a company, Allinea has built an excellent and enviable reputation for product quality and innovation. Allinea DDT 2.6.1 is further testament to our vision and ongoing investment in product innovation. This latest version has been beta tested for several weeks now and is now ready for release onto the market."

Allinea DDT also includes support for debugging memory errors in CUDA kernels, such as reading or writing beyond the end of allocated blocks of memory. A "stop on kernel launch" feature allows users to begin debug kernels automatically as soon as they are launched, in addition to the existing support for source code breakpoints.

Mike Fish concludes: "Allinea is now the fastest growing tools company in the industry and we are clearly well placed to take advantage of this lead, expanding globally and into new market sectors."

Allinea Software will be exhibiting at the Supercomputing Conference (SC'10) in New Orleans, USA from November 15-18, 2010; come and see us on booth #2305.
