TSUBAME2 Hardware Architecture

TSUBAME2 consists of more than 1400 compute nodes interconnected by high-bandwidth full bisection-bandwidth Infiniband networks. There are three node types: Thin, Medium, and Fat nodes, which differ in their equipped memory capacity among others. All compute nodes share scalable storage systems that provide 7PB of capacity.
