Again in Flash,The Titan Supercomputer at Oak Ridge National Laboratory 18,688 AMD Opteron 6274 16-core CPUs, and 18,688 NVIDIA Tesla K20X graphics cards. This Super Computer has 710TB of memory, with 598TB dedicated to the CPUs and 112TB to the GPUs.These specs make it the world’s most powerful supercomputer, but did you know it that this 299,008-core computer also is the world's fastest storage system?
The officials at Oak Ridge National Laboratory (ORNL) have decided to beef up the storage system on Titan and have selected the Spider II data storage and retrieval system from DataDirect Networks (DDN) to replace the existing system on the Titan supercomputer. At the heart of Spider II are 36 SFA12K-40 hardware devices—each capable of handling 1.12 petabytes of data. Together they will allow Titan to move 40 petabytes of data at 1.4TB/s.
While Talk about an upgrade,The bill for this machine is closing in on $100 million and it takes up 404 square meters of floor space, and consumes 8.2 MW of electricity.
