Brings together the technologies of geometric modeling,
symbolic mathematics, numerical analysis,
compilation/code generation, and formal methods to forge
new software tools for creating scientific software.
Focuses on the topics of machine vision, navigation and tracking,
robotic manipulation, distributed and cooperative
robotics, microelectromechanical systems, planning and control,
uncertainty and error, and geometric algorithms.
A system that implements a constructive theory of types. NuPrl
provides both a formal system of mathematics and a programming
language. It allows the user to express a wide variety of proof
and program-building methods as metalevel programs of the system
and use these to construct mathematical theorems and evaluate their
We develop software tools for make programs run faster on
high-performance machines such as parallel machines and uniprocessors
with deep memory hierarchies. Currently, we are working on a novel
approach to program restructuring called "data-centric compilation"
which we are using to generate blocked codes from unblocked ones and
to generate sparse-matrix codes from high-level specifications.
HyTech is an automatic tool for the analysis of embedded systems.
HyTech computes the condition under which a linear hybrid system
satisfies a temporal-logic requirement.
The Horus project has developed a modular and extensible
process-group communication system, addressing the requirements
of a wide variety of robust distributed applications.
The Computer Science Technical Report (CS-TR) project is an
ARPA-funded consortium of the top five computer science departments
(Berkeley, CMU, Cornell, MIT, and Stanford) and the Corporation for
National Research Initiatives (CNRI). The project's goals are to
further research in the electronic publication of technical reports
over the Internet and to make available the existing library of
technical reports at the member universities.
Focuses on multimedia systems technologies, including video
file servers, network transport protocols, multimedia user
interface toolkits, and video special effects.
PREDATOR is an object-relational DBMS that studies
efficient database support for complex data types.
It is based on Enhanced Abstract
Data Types (E-ADTs), and the current focus of work is
on the development of several multi-media data types.
The code base is publicly available from Summer 97.
The information capture and access research group works on
ways that computers can locate information in the ever
increasing volume of online data, determine its structure,
and extract the information for human users.
U-Net offers communication performance on par with parallel machines on
an ATM cluster of Sun workstations. It supports parallel programming
environments (such as Active Messages and Split-C) as well as
traditional networking protocols like TCP.
Active Messages -- High-performance communication
Information about developments using the Active Messages
Split-C -- A simple parallel extension to C
Information about developments of Split-C.
Information about our baby SP-2. What's installed, where to find it
and how to use it.
The Design Research Institute is an organization of collaborating
industry and academic scientists and engineers devoted to research
bringing computer science and computation technology to bear on
problems of engineering design.
The ACRI, under the direction of
Thomas F. Coleman,
with scientific computation research and its application to
engineering and scientific problems. Of particular importance
is the use of advanced computer architectures and environments.
The ACRI resides in both the
Cornell Theory Center and the
Computer Science Department.
AsTeR --Audio System For Technical Readings-- is a computing
system for rendering technical documents in audio.
QMG is a toolkit of C++ and Matlab routines for geometric
modeling, unstructured mesh generation for complicated
geometries in two and three dimensions, and finite element
solution of boundary value problems. This software is
available by anonymous FTP. The mesh generation algorithm
is based on research by S. Mitchell and S. Vavasis.
ARPA funded projects
MediaNet combines three technologies developed at Cornell to develop
a flexible, high performance testbed for storing, transporting,
processing, and using multimedia data.
