Outline CNIC Tiled Display Wall Astronomical Data Visualization
Tiled Display Wall @ 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.
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 http://dmx.sourceforge.net/ 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
Astronomical Data Visualization A PRIME 2006 Project –2006.6-8 –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
