#  Set up system:
#    page size:    100
#    # frames:     100
#    # vpages:     200
#    frame factor:  50%

sysinit	100	100	200	0.5	3

# The OS should be allocated the first 16 pages of virtual memory and
# the first 16 frames of physical memory.  Let's see:
show	pmt
#
# Queue up an arrival with some memory reads to successive process pages:
arrival	1000	1	20	12
MemAccess	1000	1	125
MemAccess	1000	3	225
MemAccess	1000	5	325
MemAccess	1000	7	425
MemAccess	1000	9	525
#
# It should take 1 tick to make the process arrive.  Its 12 pages should
# be loaded into virtual memory immediately after the 16 pages allocated
# to the OS.  Let's see if that works:
simto	1
show	1000
show	pmt
# After two more ticks its 0-th page to be loaded into frame 16 and the
# process should be in the run state:
simto	3
show	1000
#
# The next tick should cause a page fault for page 1 of the process, and
# two more ticks should result in a page load to frame 17 of RM and the
# process being back in the run state:
simto	6
show	1000
show	pmt
#
# The pattern should repeat itself for every three ticks until the process
# has got 6 pages loaded:
simto	21
show	1000
show	pmt
#
# The process's frame limit should be 6, so the next read should trigger
# a page replacement, recycling the first page that was loaded for the
# process:
MemAccess	1000	11	625
simto	24
show	1000
#
# Run the process to completion:
simto	35
