The Chroma Software System for Lattice QCD

We describe aspects of the Chroma software system for lattice QCD calculations. Chroma is an open source C++ based software system developed using the software infrastructure of the US SciDAC initiative. Chroma interfaces with output from the BAGEL assembly generator for optimised lattice fermion kernels on some architectures. It can be run on workstations, clusters and the QCDOC supercomputer.Comment: poster presented at Lattice2004(machines

System for producing chroma signals

A method for obtaining electronic chroma signals with a single scanning-type image device is described. A color multiplexed light signal is produced using an arrangement of dichroic filter stripes. In the particular system described, a two layer filter is used to color modulate external light which is then detected by an image pickup tube. The resulting time division multiplexed electronic signal from the pickup tube is converted by a decoder into a green color signal, and a single red-blue multiplexed signal, which is demultiplexed to produce red and blue color signals. The three primary color signals can be encoded as standard NTSC color signals

Chroma Pneuma

I was conducting process trials based on water. As I reacted to what was being produced, I found myself having little moments of joyful discovery. I was fascinated to observe patterns and implied textures that were generated through natural process; these patterns mimic the fractal nature of repetitive structures on a micro to macro scale that we see within our natural world. Patterns whose resemblance ranges from formations found in semi- precious stones, such as jasper or agate; to satellite imagery of branching river systems and sites of massive erosion. While the implied texture of the work was being influenced by water and stone; the color selections for the pieces are abstractly influenced by the deeper understanding of the personal interactions humans have with color from and cultural, spiritual and psychological standpoint. I wish the overall environment of the installation to inspire a sense of wonder and excitement, so the viewer can explore the work in not only the realms of the physical senses but also transcendental
