Abstract. Remote sensing observations in the mid-infrared spectral region (4–15 µm) play a key role monitoring composition of Earth's atmosphere. Mid-infrared measurements from satellite, aircraft, balloons, and ground-based instruments provide information on pressure, temperature, trace gases, aerosols, clouds. As state-of-the-art deliver vast amount data global scale, their analysis may requi...

Graphics processing units provide an astonishing number of floating point operations per second and deliver memory bandwidths of one magnitude greater than common general purpose central processing units. With the introduction of the Compute Unified Device Architecture, a first step was taken by nVIDIA to ease access to the vast computational resources of graphics processing units. The aim of t...

From our experience in using RDF stores as a backend for social media streams, we pinpoint three shortcomings of current RDF stores in terms of aggregation speed, constraints checking and largescale reasoning. Parallel algorithms are being proposed to scale reasoning on RDF graphs. However the current efforts focus on the closure computation using High Performance Computing (HPC) and require pr...

There is increased interest in the use of graphics processing units (GPUs) for general purpose computation. This is because GPUs are almost two orders of magnitude faster in terms of floating point throughput compared to conventional CPUs. In this paper we investigate the use of graphics processing units for accelerating signal processing algorithms, specifically FIR filters and the FFT. We des...
