The Alignment Effect of Brightest Cluster Galaxies in the SDSS
Rita S. J. Kim, Jim Annis, Michael A. Strauss +5
One of the most vital observational clues for unraveling the origin of Brightest Cluster Galaxies (BCG) is the observed alignment of the BCGs with their host cluster and its surrou…
Detecting Clusters of Galaxies in the Sloan Digital Sky Survey I : Monte Carlo Comparison of Cluster Detection Algorithms
Rita S. J. Kim, Jeremy V. Kepner, Marc Postman +15
We present a comparison of three cluster finding algorithms from imaging data using Monte Carlo simulations of clusters embedded in a 25 deg^2 region of Sloan Digital Sky Survey (S…
Parallel Programming with MatlabMPI
Jeremy Kepner
MatlabMPI is a Matlab implementation of the Message Passing Interface (MPI) standard and allows any Matlab program to exploit multiple processors. MatlabMPI currently implements th…
A Multi-Threaded Fast Convolver for Dynamically Parallel Image Filtering
Jeremy Kepner
2D convolution is a staple of digital image processing. The advent of large format imagers makes it possible to literally ``pave'' with silicon the focal plane of an optical sensor…
Exploiting VSIPL and OpenMP for Parallel Image Processing
Jeremy Kepner
VSIPL and OpenMP are two open standards for portable high performance computing. VSIPL delivers optimized single processor performance while OpenMP provides a low overhead mechanis…
