optional arguments:
-h, --help show help message and exit
-t TRACEFILE, --tracefile TRACEFILE
The trace file to emulate with, this argument will be
ignored is --directory is added
-d dir, --directory dir
Emulate all trace files in the given directory, enable
this will ignore trace-file argument
-o outfile, --output outfile
The file path to write emulation information to. Add
-v to save the whole emulation detail.
--cpu-clock CPU_CLOCK
Clock for blocks running at CPU speed(default="2GHz")
--clock-cycle CLOCK_CYCLE
Ticks to run in one cycle(default=1000)
--tape-domain TAPE_DOMAIN
The domain# in one tape(default=64)
--tape-length TAPE_LENGTH
The spacial length of each tape(default=80)
--group-tape GROUP_TAPE
The tape# in one group(default=512)
--l2-size L2_SIZE The size of L2 Cache(default=4MB)
--l2-assoc L2_ASSOC The associativity of L2 Cache(default=8)
--l2-r-latency L2_R_LATENCY
The read latency (cycle) of L2 Cache(default=1)
--l2-w-latency L2_W_LATENCY
The write latency (cycle) of L2 Cache(default=1)
--l2-access-latency L2_ACCESS_LATENCY
The assess latency (cycle) of L2 Cache(default=6)
--l2-shift-latency L2_SHIFT_LATENCY
The shift latency (cycle) of L2 Cache
RacetrackMemory(default=1)
--l2-miss-penalty L2_MISS_PENALTY
The penalty (cycle) when a L2 Cache miss
occurs(default=100)
-pm {baseline,rw,w+r,rw+r,rw+w+r,w+r+r}, --port-mode {baseline,rw,w+r,rw+r,rw+w+r,w+r+r}
Determine how the r/w ports are placed on a tape
-ps {dynamic,static}, --port-selection {dynamic,static}
Port selection policy for every r/w instr
-pp {lazy,eager}, --port-update-policy {lazy,eager}
The tape will remain where it is or move to default
place after r/w operation
-sp {con,way}, --set_partition {con,way}
Set partitioning policy, "con" for continuous, use
"way" to divide sets into different ways
-pre, --preshift Enable preshift for next i/o instr
-I MAXINSTS, --maxinsts MAXINSTS
Total number of traces to emulate (default: run
forever)
-V, --verbose Verbose mode, show debug info
其中与报告中的几种策略相关的有
-pm {baseline,rw,w+r,rw+r,rw+w+r,w+r+r}, --port-mode {baseline,rw,w+r,rw+r,rw+w+r,w+r+r}
对应报告中的端口摆放策略，rw对应5RW, w+r对应2W+12R, rw+r对应2RW+10R,
rw+w+r对应2RW+2W+6R, w+r+r对应4W+8R
-ps {dynamic,static}, --port-selection {dynamic,static}
对应报告中的端口选择策略
-pp {lazy,eager}, --port-update-policy {lazy,eager}
对应报告中的端口移动策略
-sp {con,way}, --set_partition {con,way}
对应报告中的Set划分策略, "con"代表continuous,
"way"代表corss-way
-pre, --preshift 对应报告中的Preshift策略
使用例子：
python3 ./racetrack.zip -pm 'w+r+r' -ps 'dynamic' -pp 'lazy' -sp 'way' -pre -t trace/462.libquantum.trace
或者解压出来之后，
./__main__.py -pm 'w+r+r' -ps 'dynamic' -pp 'lazy' -sp 'way' -pre -t trace/462.libquantum.trace
