Jaguar or OLCF-2 was a petascale supercomputer built by Cray at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. The massively parallel Jaguar had a peak performance of just over 1,750 teraFLOPS (1.75 petaFLOPS). It had 224,256 x86-based AMD Opteron processor cores,[2] and operated with a version of Linux called the Cray Linux Environment.[3] Jaguar was a Cray XT5 system, a development from the Cray XT4 supercomputer.

In both November 2009 and June 2010, TOP500, the semiannual list of the world's top 500 supercomputers, named Jaguar as the world's fastest computer. In late October 2010, the BBC reported that the Chinese supercomputer Tianhe-1A had taken over the top spot, achieving over 2.5 quadrillion calculations per second, thereby bumping Jaguar to second place. The November 2010 TOP500 list confirmed the new rankings.[4][5]

In 2012, the Cray XT5 Jaguar was upgraded to the Cray XK7 Titan hybrid supercomputing system by adding the Gemini network interconnect and fitting all of the compute nodes with Kepler generation Nvidia GPUs.[6][7][8]
