The team down at the Texas Advanced Computing Center (TACC) just doesn’t seem to want to rest. In fact, they’ve done just the opposite, pressing down harder on the accelerator pedal by improving the performance of its Stampede supercomputer by nearly doubling the Rmax of the system – in just six months. The system now delivers an impressive 5.18 petaFLOPS of performance in 182 cabinets while using 75 miles of Infiniband cables!


This performance boost was enough to move Stampede from the seventh fastest supercomputer on Earth, according to the list, to number six. I think that demonstrates the amazing leaps the high performance computing (HPC) industry is making, and the speed in which this is all occurring is mind-boggling.

Of course the world’s attention is always capitaved by the speed of these Super Computers, and the Top500 List does a great job of doing that. However, the real excitement comes from the research and science that is enabled. TACC rightfully so is proud of not only the power of its computing resources, but also how much tools like Stampede will help scientists do more. Under the theme of open science research, researchers at any U.S. institution can have access to utilize Stampede through a proposal and approval process.

We no longer need to imagine a day when researchers across the U.S. have access to the most powerful tools in modern science – high performance computing.

Congratulations again to all of the newest members of the Top500 – and cheers to what we will discover and accomplish with this great computing power!
