After recently passing Oak Ridge National Laboratory's acceptance tests in record time for a large supercomputer, the lab's new Cray X1E system, nicknamed Phoenix, already is delivering unprecedented performance on some of the nation's most daunting "grand challenge" science problems.
"We subjected the Cray X1E system to rigorous acceptance tests, and it passed with flying colors," said Thomas Zacharia, ORNL's associate laboratory director for Computing and Computational Sciences. "We already have five grand challenge projects running on it and are seeing a lot of breakthrough science that has not been possible on other contemporary HPC systems."
With peak performance of 18.5 teraflops, ORNL's Cray X1E is one of the most powerful high performance computing systems in the world. Most HPC systems today achieve less than 10 percent of their peak performance on the most challenging scientific problems. The Cray X1E's high-bandwidth, low-latency architecture enables it to sustain far higher percentages on these problems, making the Cray system even more powerful in practice.
The five grand challenge problems already running in production mode at large scale on ORNL's Cray X1E supercomputer are:
"We are excited that the Cray X1E system is already enabling research communities to make breakthrough advances on a range of grand challenge science problems," said Cray Inc. president and CEO Peter Ungaro. "We are committed to helping ORNL meet its aggressive goal to create the world's most powerful computing resource for open science."
