Under the Debugger Software Enhancement program for Petascale production grade tools, awarded to Allinea Software Inc. by Oak Ridge National Laboratory in Q2 2009, Allinea’s Distributed Debugging Tool (DDT) is setting new levels of debugger scalability on Jaguar, a Cray XT5 and one of the world’s largest supercomputers.
In Q2 2009, Allinea began a collaborative project with ORNL to extent the scalability of its DDT product. The project goal is to enable ORNL’s users to debug MPI applications that span many hundreds of thousands of processors, while delivering novel capabilities that can radically simplify this task. Following successful completion of the early stages of the project, Allinea was able to demonstrate that DDT can debug a 220,000 process application running on ORNL’s Jaguar supercomputer.
