Beowulf
The Center for Advanced Computing Research at Caltech has been at the forefront of developing Beowulf systems and employing these low cost commodity parallel systems in a variety of scientific and engineering applications. Beowulf-class computers utilize cost-effective, mass-market, commodity off-the-shelf technologies to deliver scientific and engineering computational cycles at the lowest possible price.

K-12 Beowulf (Hrothgar)
The Hrothgar Project is an effort started by the Center for Advanced Computing Research (CACR) at Caltech to explore the utility of high end (university research caliber) computers within high school curricula. A Beowulf Class PC cluster has been selected as the initial platform

Continuum Computer Architecture (CCA)
The fundamental concept underlying CCA is that a general global model of parallel computation may be synthesized through a structure of higly replicated primitive functional blocks that unify in a single fine-grain element the basic properties of logic operations, information storage and naming, and information transfer and routing.

Digital Puglia
Digital Puglia is a prototype digital library of remote sensing datacovering the Puglia region of S.E. Italy. There is a web-based interface and fault-tolerant distribution system that can fuse heterogeneous data and metadata. A major thrust is the possibility for the user to initiate arbitrary high-performance processing on the data to extract knowledge.

The Digital Sky
Federating the Sky Surveys
Large-area digital sky surveys are a recent and exciting development in astronomical research. The combination of terabyte/teraflops computational resources with the recent large-area surveys in optical, infrared, and radio wavelengths will provide unprecedented capability for astronomical research.

HTMT (Hybrid Technology Multithreaded Architecture)
This study effort investigates a computer architecture that, combined with a hybrid technology strategy, exploits these new technologies to achieve revolutionary performance.

NPACI
Major Objective: Distributed, national metacomputing infrastructure Teraflops-scale resources Enabling of data-intensive computing Integration of education and outreach Broadening of the community Partnerships with vendors.

Scalable I/O
The Scalable I/O Initiative, a project of the Concurrent Supercomputing Consortium, systematically investigates a primary obstacle to effective use of current gigaflops-scale and future teraflops-scale computing systems: getting data into, around, and out of the system.

Scientific Data Archives
Many scientific endeavors produce large quantities of heterogeneous data that is to be analyzed by loose, distributed collaborations. Scientific data, in contrast to text or image data, is often useless without sophisticated, customized data-mining and knowledge extraction tools.

SF Express
The Synthetic Forces Express (SF Express) project began in 1996 with the goal of investigating the use of high-performance computers as a means of supporting very large-scale Distributed Interactive Simulations (DIS).

XSIL
The Extensible Scientific Interchange Language (XSIL) is a flexible, hierarchical, extensible, transport language for scientific data objects.
