FACOM VP Supercomputer of Parallel Pipeline Processing System Has Achieved 7.5 Ns Machine Cycle

摘要

At the end of 1983 Fujitsu will begin to deliver its FACOM VP supercomputer, which has a machine cycle of 7.5 ns and a maximum performance of 53 MFLOPS. Its main storage can be expanded to 256 megabytes, and 64 kiloBIT static RAMs with an access time of 55 ns are used as its elements. A parallel pipeline processing has been adopted as the means of attaining high speeds. The vector registers have a maximum capacity of 64 kilobytes, and the transfer rate between them and the main storage is 4 gigabytes per second. An effective computing speed of 7.5 ns (of one pipeline operator) has been achieved thanks to the adoption of ingenious design features in the circuit configuration and to the inheriting of the M-380 technology. The target in development is to obtain a high vectorizing ratio throughout a broad range of scientific and engineering computations. In order to attain this, even the macro operations and conditional statements are subject to vectorizing. In addition, an interactive vectorizer has been provided as a tool in order to make it possible to improve the vectorizing ratio by means of tuning. (ERA citation 11:012525)
