Outline CNIC Tiled Display Wall Astronomical Data Visualization
Tiled Display CNIC A Tiled Display Wall (TDW) is a large- scale high-resolution display CNICs TDW is setup at 2005, supporting by Chinese Academy of Science. Uses a five by four grid of LCDs and 21- nodes cluster running Rocks (with CentOS installed). 1Gigabit network for each node.
LCD grid ViewSonic 17 LCDs
1+20 Cluster IBM xSeries 226 Server –Xeon2.8GHz –1G Memory (frontend 3G) –Dual Gigabit Network –73G SCSI Harddisk –Nvidia 128M Video adapter
Visualization Software Package Rocks Viz Roll – SDSC SAGE - EVL/UIC
Rocks Viz Roll DMX - Distributed Multihead X Key Soft –Xdmx:a proxy X server that provides a multi-head support for multiple displays attached to different machines. –Chromium:a system for interactive rendering on clusters of graphics workstations –Cg:nVidia Toolkit
Applications Based on Rocks Viz OpenGL App –QMView –PyMol –VMD –ParaView Image Viewer (not very well) –xnview, gthumb, ImageMagic
SAGE Scalable Adaptive Graphics Environment SAGE is a graphics streaming architecture for supporting collaborative scientific visualization environments with potentially hundreds of megapixels of contiguous display resolution. Key Soft –QUANTA, Readline, SDL, GLUT –SAGE/Sage UI
Applications Based on SAGE Image Viewer –JuxtaView, imageviewer(10kx10k), Magic Carpet OpenGL –Qmview Video Viewer –MPlayer Collaboration –VNCViewer Others –Rasmol, lambdaCam
Others MPlayer VNC
Astronomical Data Visualization A PRIME 2006 Project – –Supported by NSF –Using CalIT2 TDW and CNICs TDW –Finished by Elaine Liu (UCSD) at CNIC To remotely visualize high resolution astronomical images on UC San Diegos tile display wall while controlling at CNIC and to gain more knowledge about astronomy.
Software & Data Software –SAGE –JuxtaView Server –JuxtaSCUI/SAGE UI Astronomical Data –SDSS –DSS –Data from NASA
