TotalView Technologies announces availability of memoryscape 2.0 for MAC OS X

Newest Version of Powerful Memory Debugger Enables MPI and Remote
Application Debugging

Natick, MA- May 29, 2007 - TotalView Technologies, the world's leading
provider of debugging and analysis software solutions for the multi-core
age, today announced the availability of MemoryScape 2.0, a new version of
its powerful memory debugger for Mac OS X applications. MemoryScape 2.0
extends the product's capabilities to allow memory debugging of MPI and
remote applications, among other advanced features.

MemoryScape is an easy-to-use, graphical, interactive memory debugger that
helps developers identify, inspect and resolve difficult memory problems in
C, C++ and Fortran, including complex multi-process and multi-threaded
programs for Mac OS X. Designed to be an integrated part of the software
development process, MemoryScape allows developers 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 save and
compare memory states and compile sophisticated memory reports. In
addition, MemoryScape is non-intrusive, so developers can find memory
problems without recompiling.

"Memory bugs are one of the most frequent and challenging issues that a
developer has to deal with," said Addison Snell, vice president and general
manager of Tabor Research, a market intelligence firm specializing in HPC.
"There is a real need in the high-performance computing market for simple,
easy-to-use debugging tools that can enable developers to quickly find and
resolve difficult memory problems."

MemoryScape 2.0 includes the following new features:

MPI Application Memory Debugging

* MemoryScape works with MPICH 1 and 2 , LAM, Open MPI, MVAPICH, Quadrics,
MPT, Intel MPI, IBM POE, and Sun Cluster Tools

Remote Application Memory Debugging

Views into Heap Allocation

* Look at the data contained with a heap block

Improved Navigation

* Switch from view to view within the same process

* Navigate across a browser like history list

Time Stamping of Memory Events

Filter Heap Data Based on Backtrace ID

Wide Hardware and Operating System Support

* MemoryScape supports Apple OS X (Power and Intel). In addition, it also
supports Linux (RedHat and SuSE varieties on x86, AMD64, Intel 64bit x86,
ia64 and Power) and Unix (AIX, Solaris Sparc and Solaris AMD64)

Team Licensing

* Process token-based licensing

* Tokens can be aggregated to support rare large jobs

"We are dedicated to building on the success of the 1.0 version to extend
MemoryScape's debugging capabilities for Mac OS X," said Dick Andersen,
vice president of sales and marketing at TotalView Technologies. "These new
features significantly enhance MemoryScape's functionality and will enable
developers to achieve even greater productivity and quality improvements as
they continue to tackle the challenges of developing multi-core,
multi-threaded applications."
