   AGENDA ITEM 1:  MINUTES OF THE JANUARY 10, 1990 MEETING

 

   Motion made, seconded and passed to approve the minutes of the

   January meeting.

 

   AGENDA ITEM 2:  COMPUTING CENTER REPORT (WILLIAMS)

 

   Mainframe utilization rates continue to grow at about the same

   rate as they have for the past few years.  VM1 utilization during

   January, 1990, was up 20% over January, 1989.  The number of si-

   multaneous logged users on VM1 approaches 1000 at times.

 

   Usage levels on VM2 have doubled in the past year, primarily due

   to the addition of the CAD/CAM system.  Users may have noticed an

   occasional slowdown of the system during heavy batch usage or

   when large CAD/CAM jobs were running.

 

   Our MVS system is close to full saturation and has been sustain-

   ing very high paging rates.  Although special measures were taken

   to ensure the smooth functioning of the last student registra-

   tion, the system was very close to its limit, and additional

   measures will have to be taken before the next registration.

 

   The gradual increase in utilization has had little impact on gen-

   eral users thus far, though throughput on numerically intensive

   jobs has degraded significantly.  When full saturation is

   reached, however, the effect is usually dramatic.  Since the sys-

   tems are not far from true saturation, measures to decrease usage

   may have to be taken soon if funds are not available to upgrade

   the computers.  The committee may want to consider recommending

   measures to deal with the problem.

 

   One measure that has already been taken has been to adjust rates

   to encourage night usage.  Currently the cost of running an

   interactive job during the day is 18 times the cost of running it

   under night and evening VM Batch.  Increasing this cost differen-

   tial would probably not change usage patterns further.

 

   With the current state revenue shortfall, the University's re-

   quest for a special initiative for central computing, while

   viewed favorably by the state, is unlikely to be funded.

 

 

   AGENDA ITEM 3:  SUBCOMMITTEE REPORTS

 

   The Personal Computer subcommittee report was distributed and

   will be discussed at the next Computer Committee meeting.  The

   report was based on survey results from each college.

 

   The User Services subcommittee also distributed a report to be

   discussed at the next Computer Committee meeting.

 

 

 

   AGENDA ITEM 4:  ADDITIONS TO THE AGENDA

 

   None.

 

   The next meeting will be held on March 7 at 3 p.m. in Burruss

   400.  The final meeting for this academic year will be held on

   April 4.

 

   Meeting adjourned at 3:49 p.m.
