About ASCR Facilities...
ASCR provides several supercomputing facilities and advanced scientific networks along with programs to utilize these facilities.
Supercomputers or massively parallel high-performance computers, by every definition describes machines that employ very large numbers of processors in parallel to address scientific and engineering challenges. "Massively parallel processing" splits up a task or problem and parcels it out to multiple processors that work simultaneously but in concert to quickly supply results. High-performance computers link hundreds or thousands of processors - the computer chips that perform most calculations - in massively parallel configurations. Some of the processors in high-performance computers are specially designed for their purpose. In others, the processors are similar to the commercially available ones found in home computers, but they're linked by custom-made hardware and software that lets them work together quickly and efficiently.
High-performance computers carry out billions or even trillions of calculations each second - powerful enough to simulate complex physical, biological and chemical phenomena. Supercomputers help scientists understand these processes at unprecedented levels - from individual atoms for nanoscale engineering to the entire planet for global climate studies. High-performance computers also are powerful enough to provide insight into systems and process by simulating them with great detail over relatively long times.
