ISTC consists of the Information Processing Center and the University Library. ISTC's main purpose is to provide information services through computer facilities and library services.

The Graduate School will start from April 1997. It was very important to prepare the necessary computer equipment for the graduate school during FY 1996. Besides providing regular services, IPC staff provided the following new supports during FY 1996.

• Support to move Labs' workstations where research rooms were relocated due to the establishment of the Graduate School.
• Choose suitable workstations for Graduate School and install them to each Lab.
• Support to improve MUSE system for Graduate School.
• Make ready a new Computer Exercise Room 7.
• Replaced about 100 workstations in Computer Exercise Room 3 and 4 with minimum interruption in order to provide state of art computer-technology.
• Make ATM available on the Research Ring.
• In addition to 6,900 volumes of books with the regular budget, special books for the graduate school are being purchased in two years: 4,500 volumes in 1996 and 3,300 in 1997.

   It is very important for the effective use of highly parallel computer to understand its overall performance. But it depends on many factors, and it show very complicated behavior. We propose a new method to predict the overall performance using simple models built from a combination of the degree of parallelism, memory caching mechanism and capacity, communication cost and so on. Experimantal results of performance estimation on some real highly parallel computers show the feasibility of this method.
