    In this scenario, computational fluid dynamics simulations of turbulence are performed with 64 GPUs and an optimized CFD algorithm using communication/computation overlapping. Detailed timings reveal that the GPUs' internal calculations are so efficient that operations related to data exchange between compute nodes now cause a scaling bottleneck on all but the largest problems.

    This article describes a GPU-based high-performance computing method to tackle the protein-DNA docking problem. GPU-specific algorithmic techniques are developed to accelerate a docking algorithm that integrates Monte Carlo simulation and simulated annealing. Experiments show that such improved computation speed accelerates the conformational space sampling of the algorithm and increases the chanc... View full abstract»

    Algorithms designed to efficiently solve the classical N-body problem of mechanics fit well on GPU hardware and exhibit excellent scalability on many GPUs. Their computational intensity makes them a promising approach for other applications amenable to an N-body formulation. Adding features such as autotuning makes multipole-type algorithms ideal for heterogeneous computing environments. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3677 KB) | HTML iconHTML

    GPUs provide impressive computing power, but GPU programming can be challenging. Here, an experience in porting real-world earthquake code to Nvidia GPUs is described. Specifically, an annotation-based programming model, called Mint, and its accompanying source-to-source translator are used to automatically generate CUDA source code and simplify the exploration of performance tradeoffs.

    Based on frequency-domain system-identification techniques combined with an optimal model-order selection, this modeling method efficiently simulates microwave radiometers. A broadband microwave receiver (with astronomical applications) is modeled and simulated to illustrate the technique. This particular receiver is a challenging case because it samples cosmic microwave background (CMB) low-power... View full abstract»
