The Jaguar supercomputer located in Tennessee, USA is to get an upgrade which should see it become the fastest supercomputer in the world. Currently the title of fastest supercomputer is held by the K computer located in Kobe, Japan.
The Cray Jaguar currently holds the number 3 spot with a performance of 1.759 Teraflops while the K computer is able to hit 8.162 Tflops. The Jaguar uses 224,162 six-core Opteron CPUs running at 2.6GHz. The upgrade will replace all the existing Cray XT5-HE nodes with Cray XK6 nodes which will be running the new 16-core AMD Interlagos processors. This upgrade is expected to boost performance three-fold.
In mid-2012 a second round of upgrades will commence and will see the new XK6 nodes being augmented by dual NVIDIA Kepler GPUs which are expected to boost the performance of the new super computer to 9 times that the original Jaguar configuration before the XK6 upgrade. This new supercomputer will be dubbed Titan and is expected to deliver a speed in the 10-20 Petaflop range.
