Introducing TotalView and MemoryScape Interoperability

TotalView Technologies, a provider of interactive analysis and debugging tools for serial and parallel codes, today announced the opening of beta for MemoryScape 3.0, TotalView 8.7, and ReplayEngine 1.5.  The updated versions of these products incorporate the intuitive MemoryScape interface into the TotalView debugger, allowing either product to be launched from the other; and advance ReplayEngine for long-running applications.

TotalView is a comprehensive source code and memory debugging solution that dramatically enhances developer productivity by simplifying the process of debugging data-intensive, multi-process, multi-threaded, or network-distributed applications.

ReplayEngine records program execution history and replays it for diagnosis with TotalView. MemoryScape is a graphical, dynamic memory analysis tool that helps developers, build engineers and QA engineers identify and resolve difficult memory problems in C, C++ and Fortran. 

MemoryScape 3.0, in addition to the new interoperability with TotalView, introduces instant array bounds detection for Linux platforms with the new Red Zones feature and the capability of detecting and controlling low available memory conditions in the heap.  ReplayEngine 1.5 allows users to record and replay just the last few minutes of long- running programs and continues support for an ever-growing number of MPIs. TotalView 8.7, with MemoryScape and its new features available from within a debugging session, provides support for heterogeneous debugging across several Linux platforms and extends remote debugging capabilities to Power PC32 systems.

“This release responds to critical needs among our HPC customers. Heap array bounds errors can be detected on any process in a large parallel job; Out of Memory conditions cause a significant fraction of job terminations on large clusters. With TotalView or MemoryScape scientists can easily track down both kinds of errors in their parallel codes and get their jobs to successfully generate scientific results.” said Chris Gottbrath, director of product management at TotalView Technologies. “These latest versions of our products extend their interoperability and the ease with which developers can use them in pinpointing their most baffling and elusive software bugs.”

TotalView Technologies is a sponsor at this week’s International Supercomputing Conference in Hamburg, Germany, exhibiting in booth 115, and will host a Birds-of-a-Feather session, Multiple Ways to Debug: User’s Tips & Tricks.
