Earth Simulators

Presentations | English

The Earth Simulator, developed by the Japanese government's initiative "Earth Simulator Project," is a highly parallel vector supercomputer system that consists of 640 processor nodes and interconnection network. The processor node is a shared memory parallel vector supercomputer, in which 8 vector processors that can deliver 8GFLOPS are tightly connected to a shared memory with a peak performance of 64GFLOPS. The interconnection network is a huge non-blocking crossbar switch linking 640 processor nodes and supports for global addressing and synchronization. The aggregate peak vector performance of the Earth Simulator is 40TFLOPS, and the intercommunication bandwidth between every two processor nodes is 12.3GB/s in each direction. The aggregate switching capacity of the interconnection network is 7.87TB/s. To realize a high-performance and high-efficiency computer system, three architectural features are applied in the Earth Simulator; vector processor, shared-memory and high-bandwidth non-blocking interconnection crossbar network.
