The Titan — not to be confused with Nvidia’s graphics card of the same nam
e — is loaded with 18,688 AMD Opteron 6274 16-core CPUs, and 18,688 Nvidia
Tesla K20X GPUs. If you’re counting, this makes Titan a 299,008-core comput
er. It sports 710TB of memory, with a split of 598TB dedicated to the CPUs a
nd 112TB to the GPUs. Before this new goal of upgrading Titan’s storage, it
had 10 petabytes of storage, running at 240GB/sec. The rig can perform arou
nd 27 petaflops, and the entire unit cost $97 million. Now, not content with
Titan’s superb performance and mind-boggling speed, Oak Ridge is stepping
up Titan’s storage game, adding a new file system that has 40PB of storage.
Rather than simply upgrading the space, the new file system will also help
Titan reach performance speeds of 1.4TB/s. |
