The update of super-computer cray, installed in Oakridge national laboratory, allow to make this system as the fastest in the world.
This Super-computer, is called : Jaguar, it have the peak performance 1,64 petaflop. This system was able to reach the performance 1,3 petaflop during tests.
In order to increase the performance of jaguar , to 84 cabinets XT4 were added 200 additional Cray XT5. Now in the system configuration enters more than 45000 four core AMD opteron processors , 362 TB memory and 10 PB HDD. The memory bandwidth is equal to 578 TB/s, and the input-output subsystem is the bottleneck ; This system is capable of moving each second 284 GB of data. Related Products :
