The APU figure is the percentage of time the attached
processor is running.
The contention for the processor is represented
values of the numbers of users in queue1
maintained by the scheduler.

and queue2,
The next field, STORAGE, is a measure of the usage of real
storage. It is a smoothed ratio of the sum of the estimated
working sets of the users in queue1 and queue2, to the number
of pageable pages in the system, expressed as a percentage.
Due to the algorithm used by the scheduler in
entry to the active queues, the value of STORAGE 100%. determining

The scheduler contention ratio, RATIO, is a smoothed measure
of the contention for real storage, and is defined as: E+M RATIO = M is the number of users in queue1 and queue2
E is the number of users waiting to be allocated real
storage by the scheduler and, therefore, temporarily
resident in the scheduler's eligible lists.
Thus, RATIO is the ratio of active users to users being
serviced, and is 1.0 for optimum response. Optimum response
occurs when enough real storage is available to accommodate
all active users, assuming the processor can process their
commands. If E and M are both zero, the value of RATIO is set
to 1.0. Given the value of RATIO and ft, (Q1.Q2) the number of users in
the eligible list can be computed as:
E = M (RATIO-1) INDICATE USER allows a user to determine the resources used and occupied by
his virtual machine, and the I/O events that have taken place.
The following two line response is returned: PAGES: RES-nnnn is-nnnn READS=nnnnnn WRITES=nnnnnn DISK-nnnn DRUM-nnnn YTIME=nnn:nn TTIME=nnn:nn SIO=nnnnnn RDR-nnnnnn PRT-nnnnnn PCB-nnnnnn
The first line of the response displays the data from the user's VMBLeK that ls relevant to his virtual machine's paging activity and resource occupancy. RES is the current number of the user's virtual storage pages
resident in real storage at the time the command is issued. is is the most recent system estimate of the user's working
set size. Part 2. Control Program (CP) 105

READS is the total number of page reads for this user since he
logged on or since the last ACNT command was issued for his
virtual machine. WRITES is the total number of page writes for this user since he logged on or since the last ACNT command was issued for his
virtual machine. DISK is the current number of virtual pages allocated On the system paging disk for this user. DRUM is the current number of virtual pages allocated on the
system paging drum for this user.
The second line of the response gives the user his processor usage and
accumulated I/O activity counts since logon or since the last ACNT
command was issued for his virtual machine. VTIME is the total virtual processor time for the user.
TTIME is the total virtual processor and simUlation time for
the user. SIO is the total number of nonspooled I/O requests issued by
the user.
RDR is the total number of virtual cards read. PRT is the total number of virtual lines printed. PCH is the total number of virtual cards punched.
