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.

1. Besides providing regular services, IPC staff provided the following new supports during FY 1997.
   • Started to provide an OB server for students and faculty who left the University.
   • Replaced workstations in Computer Exercise Room 5กม6 and Hardware Workshops 1กม4 in order to provide the state of art computer-technology.
   • Provided 64kbps connection service to Ohu University.
   • Provided a training course on Computer Literacy to administrative staff.
   • Increased number of telephone lines to access the AINS via the port server from outside.

2. Concerning Library services, in addition to 2,900 volumes of books with the regular budget, 3,300 special books for the graduate school were purchased in 1997. 551 foreign and 150 Japanese journals, 701 in total, were purchased.

   In this paper, we present a new distributed algorithm for solving the resource allocation problem with multi-types of resources, by employing a technique called multiple matching. A merit of the algorithm is that it allocates the resources to as many processes as possible concurrently, so that only minimum processes need to wait.

Proceedings of the International Conference on Parallel and Distributed Processing Techniques and Applications (PDPTA'97), editor: H.R.Arabnia, p.801-805, CSREA, July 1997.

   In the paper, we propose a new distributed problem as an extension of the resource allocation problem, i.e. ``Allocation of Resources to Process Group'', and its solution. In this problem, there may exist deadlocks or starvation among groups. We call them ``group deadlocks'' and ``group starvation''. Our algorithm is based on an acyclic graph approach to the Dining Philosopher problem, and can allocate resources to groups of processes without group deadlock and group starvation. Also, our algorithm can be applied to a dynamic case, where processes of a group may join/leave in/off form the network environment.
