As the US Department of Energy (DOE) computing facilities began deploying petascale
systems in 2008, DOE was already setting its sights on exascale. In that year, DARPA …

The Perspective-Three-Point (P3P) problem aims at determining the position and orientation
of the camera in the world reference frame from three 2D-3D point correspondences. This …

In order to track all persons in a scene, the tracking-by-detection paradigm has proven to be
a very effective approach. Yet, relying solely on a single detector is also a major limitation …

Energy consumption is one of the major issues in today's computer science, and an
increasing number of scientific communities are interested in evaluating the tradeoff …

Many performance engineering tasks, from long-term performance monitoring to post-
mortem analysis and online tuning, require efficient runtime methods for introspection and …

With the increase in computational power in the last decade and the forthcoming Exascale
supercomputers, a new horizon in computational modelling and simulation is envisioned in …

MPI is the most prominent programming model used in scientific computing today. Despite
the importance of MPI, however, how scientific computing applications use it in production is …

Memory and I/O performance bottlenecks in supercomputing simulations are two key
challenges that must be addressed on the road to Exascale. The new byte-addressable …
