of DDT, the Distributed Debugging Tool, with powerful new capabilities
that set it apart from the competition. Major new features include
support for SCore (v5.4.0+), 3D array visualization and support for
Users familiar with DDT for parallel codes will welcome the
addition of the ability to debug non-MPI codes - such as Open-MP and
This latest release of DDT simplifies finding troublesome
processes and extreme data with a unique cross-process comparison
window. This feature examines and compares expressions and arrays
across processes in a parallel job and reports statistics on data
distribution and equivalence. With the grouping of like-valued processes
together, developers can immediately spot outlying data. A graphical
and statistical presentation of the retrieved values enables further
A 3D array visualization tool has been developed that gives
an outstanding display of values that is fully manipulable and even
has an option to view graphics in stereo with red-blue glasses.
In developing compatibility with queuing systems, such as Grid
Engine, Load Leveller, OpenPBS and PBS Pro, DDT is now the debugger of
choice for large shared clusters. The system enables users to submit
jobs and view queues at the click of a button, bringing
a consistency and simple environment that is unrivalled.
Evaluation copies are available from the Streamline Computing website
