SOFTWARE It is also important to note that many of the items presented are first cut proposals: several The enhanced Cyber 74/172 computer system will run task forces are still studying the various aspects the Network Operating System (NOS>, a standard of the expansion in order to make firm software product from CDC. NOS is the CDC recommendations in the near future. As always, replacement for KRONOS now that KRONOS is no any suggestions which you, our users, wish to Longer supported by Control Data. In returning to provide would be welcome. the use of a standard CDC supported operating system we will experience the same advantages and INTRODUCTION disadvantages we were subject to when KRONOS was a supported, evolving product. While it may not The January Newsletter carried an article always seem so, the advantages outweigh the announcing the proposed expansion of the existing disadvantages. Primarily, we are able to utilize Cyber 74 computer system at University Computer new or revised software products issued by CDC and Center. This article is intended to keep users other NOS sites; initially these products include informed as to the status of that expansion. the 1974 ANSI COBOL compiler and the CDC data management system, OMS 170. The version of the The Cyber 74 has become heavily Loaded, to the operating system which will be initially point where response time for interactive work and implemented on the system will be NOS, Release 3; turnaround for batch work are being adversely this version has some differences from our current affected. The proposed acquisition of a Cyber 172 KRONOS system, but these differences are and associated peripherals is designed to relieve relatively minor. We will eventually move to NOS, some of the Load on the Cyber 74. If the Cyber Release 4 in order to take advantage of various 172 is installed, it will be an "interactive enhanced features of the Cyber 172.

SYSTEM MANAGEMENT CHANGES This proposed acquisition of the Cyber 172 and associated peripherals has passed through numerous Assuming that we are authorized to introduce the University and State Committees and has met with enhanced system and the new operating system, we approval at all Levels so far. However, this will be making a number of other changes in order acquisition must still be approved by the Board of to take advantage of facilities within the Regents; it should not be considered official operating system and/or to provide features Long until acted upon by the Regents. However, we have requested by users. Billing will be changed to be organized and begun work on the assumption that dependent on the System Resource Unit (SRU). An the proposal will be favorably acted upon by the SRU is a single number designed to measure the Regents. An "Enhancement Steering Committee" has amount of resources a job consumes. The SRU takes been at work within UCC to coordinate the many central processing time, mass storage transfers, studies and proposals being undertaken by various and magnetic tape transfers into account; the SRU task forces.

These relationships are currently under study and the exact computation and charge CONFIGURATION schedule has not yet been determined. The equipment being added to the UCC configuration UCC will also move toward a common user number is: a) a 131K dual processor Cyber 172 with 10 scheme. That is, a single user number will be peripheral processors; b) additional nine track capable of being used for batch on the Cyber 74, tape drives; c) additional mass storage (disk) timesharing on the Cyber 74, batch on the Cyber controllers; d) a CDC 580 train printer. (Refer 172 and timesharing on the Cyber 172 if that user to the January Newsletter for a more complete number is authorized for any or all of these description.)
