Kahaner, ONR Asia [kahaner@cs.titech.ac.jp] Re: Supercomputers in Japan 7 Feb 1992 This file is named "j-supers.91" ABSTRACT. Tables of supercomputers in Japan through end of 1991. INTRODUCTION. I have distributed several lists of supercomputers in Japan, the last one 28 Sept 1990, "j-supers". Since then I have received several hundred requests for updates. Unfortunately, keeping track of this information is very difficult. Vendors as well as customers are not always enthusiastic about sharing, and I do not have the research staff to dig the material out directly. Luckily, this year, much of the work has been done by the Japanese journal, Nikkei Computer, which published an article on the subject in January 1992. The article included several pages of text, seven tables and four charts. Our translations of the tables and charts are included below. In addition, I have included translations of a few key sentences and headings of the text material. Reading this, it was clear that for the audience of this distribution, a full translation was not really necessary. In some cases I have abbreviated or otherwise shortened headings but I believe that no information has been lost. The tables and charts are accurate to the best of my knowledge, but are in no sense official. I will be happy to hear about and correct any errors or omissions. My thanks to Professor Y. Oyanagi, for making me aware of this article. Article Title: The Base of the Supercomputer Market Has Spread with Low Priced Machines Three Main Points of the Article: The total number of supercomputers shipped since 1980 reached 247 by the end of 1991. Compared to the number of the shipments at the end of 1988, shipments in 1991 increased twofold. (All numbers and comments refer to Japan in this and what follows.) An active injection of low priced machines into the market resulted in the spreading of the user strata from large industries to middle industries. Some users are using small supercomputers as a replacement for general machines or as an arithmetic calculation server on networks. Section Subtitles: 1. Middle and Small Sized Supercomputers Will Increase in Number in the First Half of the 1990's. 2. The Cumulative Shipment of Supercomputers Increased Twofold from 1989 to 1991 since Pre-1989. 3. The User Strata will Spread with Low Priced Machines and the Number of Replacements and Additional Computers will Increase in Large Companies. 4. Computers are Indispensable in the Automobile Field. A. Calculation Performance of Supercomputers is by a Simple Yardstick. 5. The Demand in the Pharmaceutical and Chemical Industry and Construction Industry is Expected to Increase. B. Three Trends Found in Introducing Supercomputers. 1. Trend 1: Introduction as a General Purpose Machine with Scientific Technology Calculation Function. * Does processing efficiency decrease with both transaction and calculation functions? 2. Trend 2: Introduction as Arithmetic Calculation Server on Network. 3. Trend 3: First Introduction of Supercomputer Creates New Need for Additional Machines. * 10 Percent of Approximately Three Thousand Design Engineers in Toyota Auto Body Co., Ltd. are Using Supercomputers. C. Problems with moving more fully into supercomputing 1. Can Users Fully Utilize Supercomputers? 2. Training Engineers for Using Supercomputers will Take Ten Years. 3. Supercomputers by Themselves Cannot be a Strategic Tool. 4. Operation Efficiency Drastically Changes with Presence of Operation "Know-How" (tuning). Table 1.
