Debugging the Future - GPU's and Petascale

David Maples, Allinea Software

To achieve results at Petascale and beyond, HPC developers are exploring a range of technologies - from GPU systems to homogeneous multi-core systems at unprecedented scale. This is leading to the most complex of software development challenges that can only be solved with help from developer tools such as debuggers.
