Rogue Wave Releases TotalView with Blue Gene/Q Support
Rogue Wave Software, the largest independent provider of cross-platform software development tools and embedded components for the next generation of high performance computing (HPC) applications, announced the upcoming release of the leading parallel debugger, TotalView® 8.11, with expanded support for the newest platforms that are advancing both the HPC and commercial markets. With the release of TotalView 8.11, debugging support will be offered for the IBM® Blue Gene/Q® platform, NVIDIA® CUDA™ 4.2, and the OpenACC® capability of Cray® CCE 8.0. TotalView 8.11 will also offer early access support for the Intel® Xeon® Phi™ coprocessor. This product release reinforces Rogue Wave's commitment to providing software tools that help developers port codes and be more productive on these platforms, which are at the forefront of the HPC market.
The IBM Blue Gene/Q pushes the edge of technology by providing a leadership-class supercomputer that has a homogenous multi-core architecture and relatively low power consumption. On the June 2012 TOP500® list of supercomputers, four of the top ten supercomputers were Blue Gene/Q's. Since February 2012, TotalView users at Lawrence Livermore National Laboratory (LLNL), which was named the top supercomputer on the list, have been utilizing a pre-release version of the TotalView debugger for porting codes to take advantage of the new system. TotalView has a precedent of being the code and memory debugger of choice with users of IBM Blue Gene supercomputers, including JuQueen, the Blue Gene/Q at Forschungszentrum JÃ¼lich.
“TotalView is our tool of choice for debugging on the Blue Gene/Q platform, especially following our extremely positive experiences with it on the predecessor JuGene machine, which was the world's largest Blue Gene/P, having approximately 300,000 cores. We need to support applications that use hybrid MPI and OpenMP, and TotalView gives us the ability to debug our very-scalable and most-complex, distributed, multi-threaded applications," stated Bernd Mohr, Deputy Department Head of Application Support at JÃ¼lich Supercomputing Centre. "PRACE users across Europe and Germany rely on JÃ¼lich to generate reliable scientific results and it is important for us to support this community with high-quality, proven development tools.” JÃ¼lich Supercomputing Centre recently upgraded its supercomputer to JuQueen, which is now Germany's fastest supercomputer and third largest Blue Gene/Q in the world.
“With leading universities and research organizations relying on us for state-of-the-art hardware and software, it is crucial that we provide our diverse set of users with easy to use development tools,” stated Giovanni Erbacci, HPC Group Leader at CINECA. “TotalView 8.11 has made it easier for our users to transition to FERMI, our Blue Gene/Q supercomputer.” CINECA is the Italian Supercomputing Infrastructure providing the high technology bridge between the academic world, research, and the world of industry.
Rogue Wave is dedicated to supporting scientists and engineers who are building and/or enhancing programs either directly in CUDA or by using OpenACC. Having seen a significant investment in GP-GPU acceleration among TotalView users, Rogue Wave is providing updated support for CUDA to the 4.2 versionM and full support for the OpenACC directives that are part of the Cray CCE compiler version 8.0.
Another key platform that is included in the TotalView 8.11 release is early-access support for the Intel Xeon Phi coprocessor, giving developers the ability to view, control, and debug codes running on both the host processor and the Intel Xeon Phi coprocessor. TotalView hooks into the Intel Language Extension for Offloading (LEO), providing seamless host to coprocessor debugging. Developers can also debug OpenMP and MPI applications that are compiled to run natively on the Intel Xeon Phi coprocessor.
“Providing continued support for large architectures is part of Rogue Wave's long-term product roadmap to support our customers' needs as they move to petascale, and eventually to exascale systems,” stated Chris Gottbrath, Rogue Wave's Principal Product Manager. “To meet this goal, Rogue Wave Software has an active program of collaboration with customers to achieve strategic goals, such as scalability.” Coinciding with the TotalView 8.11 release, Rogue Wave is offering select customers early access versions of the MRNet-enabled TotalView debugger, for use on leadership-class supercomputers such as Sequoia, JuQueen, and FERMI.
Designed for developer productivity, TotalView simplifies and shortens the process of developing, debugging, and optimizing complex code. It provides a unique combination of capabilities for pinpointing and fixing hard-to-reproduce bugs, memory leaks, and performance issues. TotalView raises the bar for debugging by providing several additional features at no extra cost, including debugging for CUDA, OpenACC, and deterministic reverse debugging, which allows users to pause, rewind, and playback the sessions to accurately identify and correct errors.
TotalView 8.11 will be available in November, 2012. You can find more information about the TotalView debugger by clicking here.
