One of the many extraordinary aspects of NASA’s successful landing of the Curiosity rover onto the surface of Mars Aug. 5 was ensuring the spacecraft had the information it would need to make its own decisions in the final moments of its descent without any help from mission controllers at Jet Propulsion Laboratory in Pasadena, Calif. And at least some of the credit can be attributed to the advanced work of two earthbound high performance computing systems called Nebula and Galaxy.
“What’s most nerve-racking is that the first time Curiosity goes through the whole landing sequence is on Mars,” said Ben Cichy, JPL’s chief software engineer for the Mars Science Laboratory, which includes the Curiosity rover and its scientific instruments. “By the time we heard about it, it was already over.” Keep reading →
Computers can’t simulate the Earth’s ever-changing climate in real time, the interaction of the human heart with each of thousands of different drugs, or the tiniest details of a nuclear weapon’s detonation.
But that could soon change. Keep reading →
NEW YORK (CNNMoney) — America is back on top in the race to claim ownership of the world’s most powerful supercomputer.
In a ranking released Monday of the world’s top 500 supercomputers, the United States scored the top spot with Sequoia, a supercomputer housed at the Department of Energy’s Lawrence Livermore National Laboratory in California. The U.S. had been trailing China and Japan in the supercomputer race since June 2010, when a Chinese system took over the No. 1 spot. Keep reading →
Researchers now have open access to the most advanced, powerful and robust collection of integrated advanced digital resources and services in the world through a $121 million National Science Foundation project.
The Extreme Science and Engineering Discovery Environment involves a partnership of 17 institutions to create a global network of computers, data and people to establish a single, virtual system that scientists can interactively use to conduct research directly from their desktops. Keep reading →
