AbstractAn SX-9 system has been installed as JSS V system to make good use of the program property written for the vector supercomputers. But the performance of the components of the supercomputer is not equally improved because of the technology trends and restrictions of hardware implementation. This paper introduces the performance characteristics of the SX-9 by comparing with those of the SX-6 and the knack of coding from the users' point of view especially focusing on the memory bandwidth and the performance of the processor (B/F ratio) and ADB (Assignable Data Buffer), a new feature of the SX-9. In some cases, the application programs run three times as fast as before by adding some directives and modifying a few loops. It is fruitful for the owner and the other users as well.
