Abstract
FUJITSU has developed pipelined supercomputers, the FACOM VP-100/200 with the latest technology and new architecture. Based on extensive analyses of application programs, the following advanced features are employed in the VP system: 1. 1) Dynamically reconfigurable vector registers with large capacity. 2. 2) Efficient vector operations for vectorizing IF-statements in DO-loops, 3. 3) High level concurrency for parallel scalar-vector and vector-vector operations, 4. 4) Powerful vectorizing compiler for utilizing the advanced features, 5. 5) Effective tuning tools to extract higher performance of application programs, and 6. 6) Keeping good affinity with general-purpose computer systems. The final goals of development of the VP system are both ease of use and higher performance for various scientific and engineering applications. These goals have been achieved successfully. This paper describes the key components to establish the ease of use and higher performance, and also describes actual performances on the VP system.
