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.

Each XT5 compute node contains dual hex-core AMD Opteron 2435 (Istanbul) processors and 16 GiB of memory.

Each XT4 compute node contains a quad-core AMD Opteron 1354 (Budapest) processor and 8 GiB of memory.

[13] The petaFLOPS Jaguar seeks to address some of the most challenging scientific problems in areas such as climate modeling, renewable energy, materials science, seismology, chemistry, astrophysics, fusion, and combustion.

Annually, 80 percent of Jaguar's resources are allocated through DOE's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, a competitively selected, peer-reviewed process open to researchers from universities, industry, government, and non-profit organizations.
