# SimMemManager Script 2
#
# Scheduling with one user process
#   - load of user process into VM
#   - load of 0-th page of user process into RM
#   - servicing page faults
#   - memory access commands
#   - LRU replacement

#  Set up system:
#    page size:    100
#    # frames:     100
#    # vpages:     200
#    frame factor:  25%
#    quantum:        3
#
sysinit	100	100	200	0.25	3
#
# Queue up an arrival with enough memory reads to reach its frame limit:
arrival	1000	1	30	12
MemAccess	1000	2	25
MemAccess	1000	4	125
MemAccess	1000	9	625
#
# ... and some to scramble the LRU ordering:
MemAccess	1000	12	50
MemAccess	1000	15	150
#
# And go beyond that to force simple replacements:
MemAccess	1000	18	225
MemAccess	1000	20	925
MemAccess	1000	22	825
#
# And finally a few more:
MemRead	1000	26	225
MemRead	1000	28	925
#
# Let's see if it reaches its frame limit at the right point:

show	1000
show	pmt
show	fmt
#
# Now let's run through the hits on resident pages to scramble the LRU
# ordering a bit:
simto	24
show	1000
show	pmt
show	fmt
#
# Now let's see some accesses that cause replacment of memory pages. First one:
simto	27
show
show	1000
show	pmt
show	fmt
# ... and the second:
simto	31
show
show	1000
show	pmt
show	fmt
# ... and the third:
simto	35
show
show	1000
show	pmt
show	fmt
# Run it almost to termination:
simto	43
show 1000
#
# All done...
