Hello, all.
I am trying to run marss.dramsim for multicore simulation. First, I made
ooo_2_th core configuration with shared L2 cache, and checkpoints of two PARSEC
benchmarks (bodytrack and blackscholes) on two parsecROI.qcow2 provided from
MARSSx86 official website. after that, I also modified util.cfg file.
The following is my util.cfg file.
-----------------------------------------------------------------
[DEFAULT]
marss_dir = /home/msc/marss.dramsim
util_dir = %(marss_dir)s/util
img_dir = %(marss_dir)s
qemu_bin = %(marss_dir)s/qemu/qemu-system-x86_64
default_simconfig = -kill-after-run -quiet
[suite parsec_bench]
checkpoints = bodytrack, blackscholes
[run parsec-roi]
suite = parsec_bench
images = %(img_dir)s/parsecROI_body.qcow2
%(img_dir)s/parsecROI_black.qcow2
memory = 4G
simconfig = -logfile %(out_dir)s/%(bench)s.log
-stats %(out_dir)s/%(bench)s.yml
-machine ooo_2_th
-corefreq 3G
-dramsim-device-ini-file ini/DDR3_micron_32M_8B_x4_sg125.ini
-stopinsns 1000000
%(default_simconfig)s
---------------------------------------------------------------------
Next, I run the simulation using run_bench.py.
./util/run_bench.py parsec-roi -d ben_out
It runs sequentially on my linux terminal, and I saw those simulation results
which is in the files named bodytrack.log and blackscholes.log. However, I
can't be sure whether It is multicore simulation or not because ipc of the
results are not same.
Here is my simulation results
[blackscholes.log]
user.base_machine.ooo_0_0.thread0.commit.ipc = 0.185967
user.base_machine.ooo_1_1.thread0.commit.ipc = 0.582412
kernel.base_machine.ooo_0_0.thread0.commit.ipc = 0.119389
kernel.base_machine.ooo_1_1.thread0.commit.ipc = 0.241613
total.base_machine.ooo_0_0.thread0.commit.ipc = 0.121494
total.base_machine.ooo_1_1.thread0.commit.ipc = 0.485627
Received simulation kill signal, stopped the simulation and killing the VM
[bodytrack.log]
user.base_machine.ooo_0_0.thread0.commit.ipc = 0.694209
user.base_machine.ooo_1_1.thread0.commit.ipc = 0.687764
kernel.base_machine.ooo_0_0.thread0.commit.ipc = 0.0408346
kernel.base_machine.ooo_1_1.thread0.commit.ipc = 0.0127316
total.base_machine.ooo_0_0.thread0.commit.ipc = 0.291307
total.base_machine.ooo_1_1.thread0.commit.ipc = 0.361208
Received simulation kill signal, stopped the simulation and killing the VM
Also, I made my checkpoints with the following way on QEMU terminal of
parsecROI.qcow2 (I downloaded it from official MARSS website)
1. cd parsec-2.1 ; source env.sh ; cd ..
2. ./create_checkpoint bodytrack; (bench command "parsecmgmt ~~" ;./stop_sim
3. finish checkpoint creation.
is it correct multicore simulation? (I think if it is correct multicore
simulation, the ipc results of both should be same) If not, please let me know
how I can run correct multicore simulation.
Thanks in advance
