The main goal of the Advanced Simulation and Computing Program (ASCI) is "to ensure the safety and reliability of the nation's nuclear weapons stockpile." The program is a collaboration between three national laboratories, and it operates some of the world's most powerful supercomputers. One of the most notable projects detailed on the ASCI Web site is the Terascale Simulation Facility (TSF). This...

Condor is a popular software tool developed by the University of Wisconsin at Madison Computer Sciences Department. It is a type of batch system that distributes computationally intensive jobs to multiple workstations, thereby creating a grid-style environment and speeding the processing time. Universities and other research institutions can download Condor at no charge, provided they agree to the...

This is the home page of an IBM research and development project that is designing a supercomputer, called Blue Gene/L, capable of 200 trillion floating point operations per second. According to the Web site, this specification "is larger than the total computing power of the top 500 supercomputers in the world today." Working in collaboration with Lawrence Livermore National Laboratories, IBM...

The NASA Advanced Supercomputing (NAS) division is part of the Ames Research Center Information Sciences and Technology Directorate. The NAS home page describes "leading-edge high performance computing and its role in many of NASA's critical missions for the 21st century." The site provides news and feature stories of NAS projects, but most of the site's information is in the Research & Technology...

The National Science Foundation (NSF) and Mississippi State University (MSU) have provided the MSU/NSF Engineering Research Center (ERC) for Computational Field Simulation (CFS). The center is concerned with issues such as "regions or volumes of space within which physical phenomena vary with position and time." Examples of these physical phenomena are compressible fluid flow (airflow around...
