totalview Technologies adds new features to industry-leading totalview and
memoryscape debuggers
New TotalView 8.3 and MemoryScape 2.1 Easier to Use for MPI Developers
Natick, MA- October 15, 2007 – TotalView Technologies, the world’s leading
provider of scalable debugging and analysis software solutions for the
multi-core era, today introduced new versions of its advanced debugging
solutions, TotalView Debugger 8.3 and MemoryScape 2.1. The products have
been updated to add to their already considerable power and simplicity,
with a focus on making it easier for MPI programmers to streamline their
application development processes.
“The new and enhanced features in TotalView 8.3 and MemoryScape 2.1
accelerate our ability to identify where and why problems occur in our
software,” said Nick Monyatovsky, software engineer at SIMULIA.
“MemoryScape 2.1 enabled us to identify memory issues and by using its
scripting interface, we were able to automate the evaluation process. Now,
the system automatically uncovers any hidden latent errors in our code with
every build, allowing our developers to proactively fix potential errors
prior to release.”
TotalView is a comprehensive source code and optional memory debugging
solution that dramatically enhances developer productivity by simplifying
the process of debugging parallel, data-intensive, multi-process,
multi-threaded or network-distributed applications. Built to handle the
complexities of the world’s most demanding applications, TotalView supports
hybrid applications that utilize OpenMP and MPI to make efficient use of
multi-core clusters. TotalView debugs applications built from components
that may have been written in different languages (FORTRAN 90 and C++, for
example) and then compiled with different compilers (Intel and GCC, for
example) – but run together as a single executable. TotalView is also
robust and easy to use, with an intuitive GUI that helps users quickly
isolate and identify the root cause of problems.
New features of TotalView 8.3 include:
Improved MPI launch: Enables customers to run TotalView without having to
re-configure their MPI installation.
Improved data view across processes/threads: Users can now see data across
many processes or threads in a single operation, helping to solve MPI and
thread bugs more quickly.
Highlight variable changes: Seeing data change as the program executes
helps identify and solve bugs more quickly.
Improved watchpoints feature: Setting a watchpoint is simpler, making it
easier to find and fix difficult problems in situations where the variable
changes in an unexpected way.
Easier to find “expand all” in data window: Toggling detailed vs. collapse
views is quicker, allowing developers to more easily work with
hierarchically structured data.
Additional new operating systems supported, including:
* Mac OS X 10.4.5, 10.4.8 and 10.4.9
* Fedora Core 7
* Ubuntu 1.06
MemoryScape is an easy-to-use, graphical, interactive memory debugger that
helps developers, build engineers, and QA testers identify, inspect and
resolve difficult memory problems in C, C++ and FORTRAN, including complex
multi-process and multi-threaded programs. Designed to be an integrated
part of the software development process, MemoryScape allows development
teams to watch for memory leaks and monitor memory usage while an
application is running. It enables developers to monitor heap memory, view
memory usage, locate memory leaks, track memory events and show corrupted
memory. Developers can also save and compare memory states and compile
sophisticated memory reports. MemoryScape is non-intrusive, so developers
can find memory problems without recompiling, and without waiting all day
for even the smallest test to run.
MemoryScape 2.1 extends the product’s capabilities to now include:
Improved MPI launch
Enables customers to run MemoryScape without having to reconfigure their
MPI installation.
Multi-file loading
Simplifies working with core files from parallel applications.
* New simplified memscript output: Makes comparison between runs easier.
* New operating systems supported, including:
– Mac OS X 10.4.5, 10.4.8 and 10.4.9
– Fedora Core 7
– Ubuntu 1.06
“We designed TotalView 8.3 and MemoryScape 2.1 to provide a better
debugging experience right out of the box, with new features to help our
customers improve productivity and find problems easier,” said Dick
Andersen, vice president of marketing at TotalView Technologies. “As the
user community for high-performance computing continues to grow, we are
committed to providing products that address the multi-core debugging needs
of all software developers, from users debugging on a laptop or single
workstation to those working on the world’s largest supercomputers.”
