Earth Simulator(ES2) System Overview


Construction of CPU

Each CPU consists of a 4-way super-scalar unit (SU), a vector unit (VU), and main memory access control unit on a single LSI chip. The CPU operates at a clock frequency of 3.2GHz. Each VU has 72 vector registers, each of which has 256 vector elements, along with 8 sets of six different types of vector pipelines: addition /shifting, multiplication, division, logical operations, masking, and load/store. The same type of vector pipelines works together by a single vector instruction and pipelines of different types can operate concurrently. The VU and SU support the IEEE 754 floating-point data format.
