Career: Architectures and Algorithms For Rapidly Growing Datasets @ University of California-Santa Barbara
9875732 Anurag Acharya The goal of this project is to evaluate Active Disk architectures which integrate significant processing power and memory into a disk drive and allow application-specific code to be downloaded and executed on the data that is being read from (written to) disk. This project takes a vertical approach spanning architectures, programming model, operating systems and algorithms. A stream-based programming model is developed for disklets and their interaction with their peers. A restricted execution environment is designed for the execution of disklets. A simulator that contains detailed models for disks, networks and the associated libraries and device drivers and relatively coarse-grain models of processors and I/O interconnects is developed. Active Disk algorithms are developed for a suite of data-intensive algorithms for relational databases, image processing and satellite data processing. The performance of these algorithms running on Active Disks is compared with that of efficient algorithms running on conventional architectures, such as clusters and SMPs.

Cise Research Instrumentation: Scalable Storage Servers For Advanced Information Systems @ University of California-Santa Barbara
9818320 Agrawal, Divyakant Acharya, Anurag University of California at Santa Barbara
Scalable Storage Servers for Advanced Information Systems
This research instrumentation enables research projects in:
- Architecture for Rapidly Growing Datasets, - A Scalable Distributed Architecture for Locating Heterogeneous Information Sources, - Data Placement and Information Access, and - Clustering Support for Parallel Digital Library/Web Servers.
To support the aforementioned projects, this award contributes in building an instrumentation infrastructure for conducting experimental research on scalable storage servers at the University of California at Santa Barbara, Computer Science Department. The funds will contribute to the purchase of a cluster of quad-processor Workstations, several single processor PCs, a Fast Ethernet switch and a Fibervault with a large number of FiberChannel disks. This equipment will be dedicated to support research in databases, operating systems, and parallel computing. The equipment will be used for several interrelated research projects, including in particular: evaluation of architectures for rapidly growing datasets, design and implementation of a scalable distributed architecture for locating information, data placement for efficient content-based retrieval and design and implementation of cluster-based servers for digital libraries. Active Disk architectures which integrate significant processing power and memory into a disk drive will be investigated. Data placement and information access techniques on active disks will be explored. A scalable distributed architecture for locating heterogeneous information sources will be developed on the proposed instrumentation infrastructure. Finally, clustering support for parrallel digital library and parallel web servers will be developed. A common theme among the proposed research projects is to provide efficient and scalable support for advanced information systems.

Dli Phase 2: Alexandria Digital Earth Prototype @ University of California-Santa Barbara
Abstract
IIS-9817432 Smith, Terence University of California, Santa Barbara $1,080,000 - 12 mos.
DLI Phase 2: Alexandria Digital Earth Prototype
This is the first year funding of a five year Cooperative Agreement award. This Project is a component of the InterLib collaboration between University of California at Berkeley, the University of California at Santa Barbara, and Stanford University. The combined interLib technologies will be demonstrated on the emerging California Digital Library (CDL), and on a testbed developed by the San Diego Supercomputer Center.
The Alexandria Digital Earth Prototype (ADEPT) Project will develop digital library environments and services that are based on the Digital Earth Metaphor. The services will support access to, and use of, heterogeneous digital information distributed across the Internet on the basis of georeference as well as other criteria. In particular the system will support the construction and use of personalized digital information collections called Iscapes (Information Landscapes). A variety of services will be provided that allow Iscapes to be developed as information service layers in which diverse information resources can be organized, accessed, and used. A characteristic feature of Iscapes is the creation of special meta-information resources indicating the joint usability of the items in the personalized collections. The project will focus on developing services that support the construction and use of Iscapes for use in learning contexts and for the creation of knowledge across a range of disciplines, including the arts, humanities, and social, physical, ] and biological sciences. The Project will focus specific attention on evaluating the effect of ADEPT services on learning in undergraduate classroom situations.
