iGrid 2002Enabling Technologies and Projects

The Globus Project conducts research and development on the application of Grid concepts to scientific and engineering computing. The Globus Project provides software tools (the Globus Toolkit) that make it easier to build computational grids and grid-based applications.

Quanta, the Quality of Service (QoS) Adaptive Networking Toolkit, is backward compatible with CAVERNsoft, and provides application developers with an easy-to-use system to efficiently utilize the extremely high bandwidth afforded by optical networks. .

Using BIC’s APBioGrid (the Asia Pacific

Bioinformatics Grid, a collection of networked

computational resources) and KOOP testbed

technology, biologists can quickly build a

complex series of computations and database

management activities on top of computational

grids to solve real-world problems.

APBioGrid mimics tasks typical of a bioinformatician – it does resource discovery over the network, remotely distributing tasks that perform data acquisition, data transfer, data processing, data upload to databases, data analysis, computational calculations and visualizations.,,,

Bandwidth Gluttony ― Distributed Grid-Enabled

Particle Physics Event Analysis

  • Argonne National Laboratory (ANL), USA
  • Caltech, USA
  • CERN (EU DataGrid Project)

This demonstration is a joint effort between Caltech (HEP) and ANL (Globus/GridFTP). Requests for remote virtual data collections are issued by Grid-based software that is itself triggered from a customized version of the High-Energy Physics (HEP) analysis tool called ROOT. These requests cause the data to be moved across a wide-area network using both striped and standard GridFTP servers.

In addition, at iGrid, an attempt is made to saturate a 10Gbps link between Amsterdam, ANL and StarLight and a 2.5Gbps link between Amsterdam and CERN, using striped GridFTP channels and specially tuned TCP/IP stacks applied to memory-cached data.

Image Feature Extraction on a Grid Testbed

  • National Center for High Performance Computing, Taiwan
  • Institute of Statistical Science, Academia Sinica, Taiwan
  • High Performance Computing Center, Rechenzentrum Universität Stuttgart

For medical imagery (confocal laser-scanning microscopes, CT, MRI and PET), NCHC does image processing, analysis and 3D reconstruction. For biotechnology imagery (e.g., microarray biochips), NCHC uses a data clustering procedure for feature extraction that provides insight into an image, such as identifying diseases caused by some protein.

Grid techniques enable the use of distributed computing resources and shared data. High-speed networks enable fast processing; typical medical doctors want the procedure accomplished in 5 seconds for use in daily operations.

TeraScope: Visual Tera Mining

  • Electronic Visualization Laboratory, University of Illinois at Chicago (UIC), USA
  • National Center for Data Mining, UIC, USA

TeraScope is a massively parallelized set of information visualization tools for Visual Data Mining that interactively queries and mines terabyte datasets, correlates the data, and then visualizes the data using parallelized rendering software on tiled displays.

TeraScope’s main foci are to develop techniques to create TeraMaps (visualizations that summarize rather than plot enormous datasets) and to develop a distributed memory cache to collect pools of memory from optically connected clusters. These caches are used by TeraScope to bridge the impedance mismatch between large and slow distributed data stores and fast local memory.,

TeraVision: Visualization Streaming over Optical Networks

  • Electronic Visualization Laboratory, University of Illinois at Chicago, USA

TeraVision is a hardware-assisted, high-resolution graphics streaming system for the Access Grid, enabling anyone to deliver a presentation without installing software or distributing data files in advance.

A user giving a presentation on a laptop or showing output from a node of a graphics cluster plugs the VGA or DVI output of the computer into the TeraVision Box. The box captures the signal at its native resolution, and digitizes and broadcasts it to anothernetworked TeraVision Box, which is connected to a PC and DLP projector. Two Boxes can be used to stream stereoscopic computer graphics. Multiple Boxes can be used for an entire tiled display.
