The SIO Visualization Cluster has made significant advancements in rendering high-resolution seismic and satellite imagery. Utilizing a 10-node IBM PC Cluster and connecting to the OptIPuter network, it visualizes a 3D reflection image of a crustal magma chamber beneath the East Pacific Rise. Notably, the ARAD 3D dataset has been visualized through tools like GVU and Vol-a-Tile, enhancing accessibility and collaboration across institutions. Future initiatives aim to develop real-time 3D visualizations for USArray data and improve health monitoring of the network.

SIO OptIPuter Visualization Cluster • 10 node IBM PC Cluster driving two 9.2 million pixels IBM T221 displays. • Connects to the OptIPuter Southern California network.
Volume Rendering at SIO • SIO provided UIC and ISI with seismic volume dataset from the ARAD 3D experiment. • 800 x 800 x 1000 (32 bits) volume highlights the first 3D reflection image of a crustal magma chamber located beneath the East Pacific Rise. • GVU uses SIO VizCluster and renders to the monitor on the master node. • Vol-a-Tile uses SIO VizCluster and renders to IBM T221 displays. • Vol-a-Tile now runs data servers on UCSD’s Storage Cluster and renders on the SIO’s Visualization Cluster over the SoCal OptIPuter network.

Accessing Data from Remote Cluster (JSOE cluster to SIO VizCluster) • Running multiple OptIPuter applications on SIO Cluster. • Retrieve scene file from storage cluster and display on IBM panels using Chromium. • Juxtaview on SIO cluster displays high resolution satellite imagery.
SIO Visual Objects Storage & Distribution • Scene files now stored on terabyte webserver on OptIPuter Storage Cluster for dissemination over OptIPuter network. • Two-fold increase in number of website visitors that downloaded the scene files.
Transferring OptIPuter technologies to other NSF Projects • RIDGE • Funded by RIDGE2K to develop visual objects of data collected with variety of methods in multiple disciplines. • GEON • Creating ‘scene’ files from geological and GIS data for San Diego and the Rockies. ROADNet: Mt. Laguna Camera • ROADNet • Generating high resolution time lapse movies on the SIO cluster from near real-time images captured by ROADNet sensors. • NASA Goddard (non NSF) • Level3 link between SIO and NASA to allow for e-science between the institutions.
Propose to build a 4 x 6 LCD tiled display driven by G5 Cluster • High resolution real time visualizations of USArray waveform data represented as 3D glyphs and combined with near real time camera images. • Provide health monitoring of entire network. USArray on the GeoWall 2
3D Tomography of Whole Earth Models • Project in progress to visualize the mantle models for the whole Earth and in particular the North American continent. • Need to visualize the process of tomography while still inverting for the model (Gabi Laske, IGPP) Figure 1:REM model combined with seismicity. Yellow blobs are isosurface representations of surface wave propagation. White dots represent earthquakes of magnitude greater than 4.0. Figure 2:Spherical representation of same data. Blue indicates positive values, where speed is high and mantle is cooler. Red indicates negative values, lower speeds and hotter mantle.
