Folding@home simulates protein folding. We do not entirely understand how proteins actually operate, but one important step is to study how proteins self-assemble or "fold." This is an extremely computationally intensive task since proteins take in the order of microseconds to milliseconds to fold, yet we can only routinely simulate over nanosecond to microsecond time scales. This system provides a new way to simulate protein folding that can break the millisecond barrier by dividing the work between multiple processors. Thus, with 1000 processors, we can break the millisecond barrier and help unlock the mystery of how proteins fold.
TAU (Tuning and Analysis Utilities) is a set of tools for analyzing the performance of C, C++, Fortran and Java programs. It collects much more information than is available through prof or gprof, the standard Unix utilities, including per-process, per-thread, and per-host information, inclusive and exclusive function times, profiling groups that allow you to organize data collection, access to hardware counters on some systems, per-class and per-instance information, the ability to separate data for each template instantiation, start/stop timers for profiling arbitrary sections of code, and support for collection of statistics on user-defined events.
WeBSET is a multi-user, Web-based special education management system that operates within Lumenation, a cross-platform middleware environment. It is a full-featured federal, state-specific, and HIPAA compliant IEP reporting system, and a screening/evaluation system which provides applications that automate all aspects of the IEP process. The system is database-driven, with the ability to automatically generate required forms and reports. The system also provides tools such as a forms builder and report builder which allow for full customization and database field insertion. System execution provides great user experience over dial up, and non-digital switch access of 26.6KB transfer rates.
NOVAS (Naval Observatory Vector Astrometry Subroutines) is an integrated package of subroutines for the computation of a wide variety of common astrometric quantities and transformations. It can provide the instantaneous coordinates (apparent, topocentric, or astrometric place) of any star or planet, and also provides general astrometric utility transformations, such as those for precession, nutation, aberration, parallax, etc. It is useful for data reduction programs, telescope control systems, and simulations.
FTOOLS is a highly modular collection of over 200 utilities for processing and analyzing data in the FITS (Flexible Image Transport System) format. Each utility performs a single simple task such as the presentation of file contents, extraction of specific rows or columns, appending or merging tables, binning values in a column, or selecting subsets of rows based on a boolean expression. It provides both generic processing and analysis utilities and utilities specific to high energy astrophysics data sets used for the ASCA, EINSTEIN, ROSAT, GRO, VELA5B and XTE missions.
SAOimage is a utility for displaying astronomical images under X11. Image files can be read directly, passed through a named pipe under Unix, or from a VMS mailbox from IRAF display tasks. It provides options for zooming, panning, scaling, coloring, pixel readback, display blinking, and region specification.
Frink is a calculating tool and programming language designed to help you in the real world. It tracks units of measurement throughout all calculations and ensures that answers are correct. It converts between systems of measurement, and has a huge library of physical data. It is both a simple calculator for quick calculations and a full-fledged programming language for large tasks. It draws high-quality graphics, handles conversions between time zones, currencies, and historical values of the U.S. dollar and the British pound, translates between several languages, does date/time math, and more.
