Description

Allinea DDT is a debugging tool from Allinea Inc., designed for debugging parallel/distributed programs using OpenMP/MPI libraries. Its primary aim is to provide a powerful and user-friendly graphical user interface, together with unique features such as so-called Parallel Stack Viewer (providing a global overview of the status of all the debugged application's threads/processes). Unlike its competitor (TotalView), the Allinea DDT provides high scalability -- it is able to debug applications consisting of more than 200,000 concurrently running processes/threads.
