TACC's Ranger supercomputer helps researchers generate realistic light signals from a black hole simulation. Astrophysicists became deeply interested in black holes in the 1960s, but the idea of an event horizon was first intimated in a paper by Karl Schwarzschild published after Einstein introduced general relativity in 1915.
Building the next generation of high performance computing professionals is an important part of the mission at TACC. For the second time in as many years, TACC welcomed a new ‘cluster' of students from South Africa to Austin as they prepare for the International Supercomputing Conference (ISC) Student Cluster Competition this June.
Simulations on XSEDE/TACC supercomputers shed light on the formation, explosion of stars in the earliest galaxies. Ab initio: "From the beginning." It's a term used in science to describe calculations that rely on established mathematical laws of nature, or "first principles," without additional assumptions or special models.
Supercomputing simulations help to predict research on the fundamental nature of the universe, characteristics of subatomic particles. For the past several years, much of the attention in particle physics has focused on the Higgs Boson, so one could be forgiven for thinking that the rest of the subatomic particle world has been figured out. In fact, many open questions remain about the precise masses and decay rates and characteristics of other particles, including mesons, quarks and gluons, which make up the protons, neutrons and electrons we're familiar with.
One aspect of XSEDE's overall outreach efforts is the Student Summer Engagement program. For eight weeks, undergraduate and graduate students from universities across the U.S. are paid to work at premier supercomputing centers with some of the most advanced computing systems in the world.
Molecules are arguably the most fidgety things in the universe. Their atoms are in constant motion, making slight position adjustments in timescales that start in femtoseconds—or one quadrillionth of a second.
We know it's out there, debris from 50 years of space exploration — aluminum, steel, nylon, even liquid sodium from Russian satellites — orbiting around the Earth and posing a danger to manned and unmanned spacecraft.
Stampede, the newest supercomputer at the Texas Advanced Computing Center (TACC) and one of the most advanced scientific research instruments in the world, fills aisle after aisle of a new 11,000-square-foot data center on the J.J. Pickle Research Campus.
