It also hosts a newer 103.2 TFLOPS supercomputer using Xeon E5649 processors.
It was initially optimized for the Pentium 4 processor and managed to immediately boost the performance of a supercomputer based on that CPU from 1.5 TFLOPS to 2 TFLOPS.
It included 62,976 processor cores (provided by 15,744 Opteron quad-core processors in 3,936 quad-socket Sun Blade server nodes) running the CentOS Linux distribution, and originally had peak performance of 504 TFlops, 123 TB memory and 1.73 PB of storage.
