Allinea DDT 4.0

The latest version of popular parallel debugging tool, Allinea DDT, has been released. Allinea DDT 4.0 includes native remote clients for Linux, Windows and Mac, which allow debugging of HPC applications wherever they are hosted – on nationwide HPC resources or out in the rapidly growing HPC Cloud.

One site already using this new capability is Oak Ridge National Laboratory (ORNL) in Tennessee, home of Titan, the large Cray XK7 system. Titan was confirmed as the world’s fastest computer last November when it achieved 17.59 petaflops and has already adopted Allinea DDT 4.0.

‘We’ve got a lot of academics, lab people, and industry people who are on the road a lot for conferences and meetings. It’s important for them to be able to work remotely,’ said David Bernholdt, a senior computational scientist in R&D at ORNL. ‘Instead of having to put statements in the code, recompile, reset and go through this whole long cycle, they’ll be able to pop up their clients on their laptops and figure out what’s going on right away.’
