TotalView Provides Open Early Access of Massive Scale Debugging

TotalView 8.13 Adds CUDA 5.5 Support for NVIDIA Kepler GPU Accelerators and Memory Debugging for Intel Xeon Phi Coprocessors

Rogue Wave Software, the largest independent provider of cross-platform software development tools and embedded components for the next generation of HPC applications, announced the beta release of its leading parallel debugger, TotalView 8.13. This beta release allows customers to work with an early-access version of the scalable architecture used to complete the successful 786,432 core debugging test announced at SC12. The architecture that set the record for debugging at scale has shown increased performance over TotalView 8.12 during tests on the latest generation Cray^® and IBM^® BlueGene™ supercomputers, as well as Linux^®-based clusters.

“We are excited to bring early-access scalability to our customers with support for some of the largest systems currently in use,” said Chris Gottbrath, Principal Product Manager at Rogue Wave. “We encourage vigorous use and detailed feedback to help us ensure the solution is stable and responsive for general availability launch.”

TotalView 8.13 also adds support for CUDA 5.0 and 5.5, including dynamic parallelism capabilities. This expanded support allows TotalView to work seamlessly with NVIDIA's latest hardware offering, the Kepler K40.

In addition, TotalView 8.13 expands support for debugging on Intel Xeon Phi coprocessors. For the first time, users can debug applications running in Xeon Phi symmetric mode with seamless transitions when the code shifts between processor and coprocessor. TotalView's MemoryScape has become the first memory debugging solution available for Xeon Phi applications.

Functionality introduced in TotalView 8.13 includes:

• Early access of scalable debugging solution.
• CUDA 5.0 and 5.5 support.
• Xeon Phi symmetric mode support.
• Xeon Phi native and symmetric modes memory debugging.
• Apple^® Macintosh OS X Mavericks support.
• Significant performance improvements.

TotalView is a scalable and intuitive debugger for parallel applications written in C, C++, and Fortran. Designed to improve developer productivity, TotalView simplifies and shortens the process of developing, debugging, and optimizing complex applications. TotalView provides a powerful combination of capabilities for pinpointing and fixing hard-to-find bugs, such as race conditions, memory leaks, and memory overruns. Providing developers the ability to step freely, both forwards and backwards, through program execution, TotalView's unique reverse debugging capabilities drastically reduce the amount of time invested in troubleshooting code.
