Streamline Computing and AMD

Streamline Computing is one of the UK's largest clustering companies with expertise in both software and hardware for the high performance computing industry.

Streamline develops software designed to simplify parallel programming and exploit the potential of high-performance computing, including DDT. DDT is quickly becoming one of the industry's most effective debugger for cluster computing.

Distributed Debugging Tool

DDT, the Distributed Debugging Tool, is a comprehensive graphical debugger designed for the complex task of debugging parallel code.
With excellent support for Fortran and C/C++ plus a comprehensive, user-friendly graphical interface, you are in control of your parallel application, whether you are working on a workstation or 1024 nodes on a high-performance cluster. DDT is designed to help developers understand their programs and offers a common interface for every compiler, language and MPI distribution. With support for AMD64 - in both 32-bit and 64-bit modes - and many other systems, DDT is designed to help developers achieve the full potential of supercomputing.
