Astrophysics Workshop on Saturation and Transport Properties of MRI-driven Turbulence


Workshop overview:
The magnetorotational instability (MRI) is currently considered the most promising mechanism for driving the magnetohydrodynamic turbulence thought to enable efficient accretion in a wide range of astrophysical systems, from young stars to neutron stars and from galactic black holes to the massive black holes found in the centers of galaxies. Understanding this process is essential for explaining the properties of quasars, active galactic nuclei, stellar X-ray sources, cataclysmic variable stars, jets from young stars and galaxy centers, and perhaps even planetary systems. Because of this broad relevance, magnetohydrodynamic turbulence driven by the MRI has been a major focus of attention in astrophysics since the early 90's. These talks address current progress and future theoretical, numerical, and experimental challenges in this field.

Workshop videos:

Workshop on General Purpose Computation on Graphics Processing Units in Astronomy and Astrophysics (AstroGPU 2007)


Workshop overview:
Graphics processing units (GPUs) are rapidly emerging as a powerful and cost-effective platform for high-performance parallel computing. The current generation of GPUs sports capabilities in TFLOP range, already an order of magnitude greater than most powerful x86 CPUs. Such an increase in computational power opens opportunities to explore previously inaccessible problems in astronomy and astrophysics. However, it also brings the challenges of adapting existing algorithms and codes (and devising new ones) to run efficiently on intrinsically massively parallel SIMD/SPMD GPU architectures. The goal of this workshop is to explore and discuss the applicability of GPUs to astrophysical problems. It will bring together astrophysicists, colleagues from other areas of science where GPGPU techniques have been successfully applied, and representatives from the industry who will demonstrate in tutorial sessions the GPU hardware, programming tools, and GPGPU techniques.

Workshop videos:
Fast Summation of Potentials - the FMM on the GPU. Real-time Digital Signal Processing in Radio-Astronomy. A Graphics Hardware-Accelerated Real-Time Processing Pipeline for Radio Astronomy. CUDA Data Parallel Algorithms. CUDA N-Body on GPU. GPU Acceleration of Scientific Applications Using CUDA. GPU Applications at the University of Maryland. GPU Computing Overview.
