C2B2 to launch new compute cluster - 10/01/2012
Over the next couple of months, C2B2 will launch a new compute cluster that boasts 212 TFlops of performance, or nearly 9x the total computing capacity of Titan. The new system will has 6336 CPU-cores, over 70,000 CUDA-cores (GPU), and 22 TB of total system memory. The funding for this new system was provided primarily by an NIH High-End Instrumentation grant.
