IDAV: Institute for Data Analysis and Visualization

The Institute for Data Analysis and Visualization (IDAV) consists of six faculty members and approximately 30 researchers and graduate students all working on interdisciplinary problems in visualization, geometric modeling, computer graphics, computational geometry, graphics architecture, and immersive technologies. We are key partners in SDAV, a DoE SciDAC III Scalable Data Analysis an Visualization Center, and in the IRTG, an International Research Training Group based at the Technical University of Kaiserslautern in Germany. We are an internationally recognized leader in the fields of visualization and computer graphics, addressing problems that range from the multiresolution display of very large-scale data, to the discovery of new visual analysis algorithms, to the design of methods to accelerate the use of graphics hardware.

Multi-GPU MapReduce on GPU Clusters

Jeff A. Stuart, John D. Owens

We present GPMR, our MapReduce library that leverages the power of GPU clusters for large-scale computing. To better utilize the GPU, we modify MapReduce by combining large amounts of map and reduce items into chunks and using partial reductions and accumulation. We use persistent map and reduce tasks and stress aspects of GPMR with a set of standard MapReduce benchmarks. We run these benchmarks on a GPU cluster and achieve desirable ... [more]
