Hi
I have questions about “Cannot get snapshot 'final'”. I found a related post a
couple months ago. But I can not get solution.
(1)
When I use the “ –stopinsns “ option to make simulation stop after a mount of
instructions, I could not get statistics convert to a readable file.
It looks that simulation could stop at the specified limit, but I could not
convert the statistics file.
At end of the logfile:
……
Completed 10087000 cycles, 9971993 commits: 94698 Hz, 85831
insns/sec: rip 00007f6b784ed646
Completed 10103000 cycles, 9991262 commits: 79624 Hz, 95892
insns/sec: rip 00007f6b784cea34
Stopping simulation loop at specified limits (10110227 iterations, 10000000
commits)
update mode count for ctx 0
update mode count for ctx 0
update mode count for ctx 0
Stopped after 10110227 cycles, 10000000 instructions and 108 seconds of sim
time
(cycle/sec: 93613 Hz, insns/sec: 92592, insns/cyc: 0.9890974752594576)
the simulation configuration I used in run_bench.py (download from Marss86
site):
# run_bench.py
……
sim_cmd_generic = 'simconfig -stats %s.stats -logfile %s.log -run -stopinsns
10m
-kill-after-finish'
……
And at produced qemu window, it shows
Execution command:
Generic simulation command: simconfig -stats %s.stats -logfile %s.log -run
-stopinsns 10m -kill-after-finish
Chekcpoints to run: ['blackscholes']
All files will be saved in: ./
Running thread with img: ./disks/parsec_image/parsec.qcow2
All Threads are started
Starting Checkpoint: blackscholes
initing the ooomachine
char device redirected to /dev/pts/4
char device redirected to /dev/pts/5
QEMU 0.12.3 monitor - type 'help' for more information
(qemu) loadvm blackscholes
(qemu) simconfig -stats ./blackscholes.stats -logfile ./blackscholes.log -run
-stopinsns 10m -kill-after-finish
simulation options received:-stats ./blackscholes.stats -logfile
./blackscholes.log -run -stopinsns 10m -kill-after-finish
Did I make some mistakes on the configurations or somewhere? Please let me
know,
great thanks!
(2) Second question about run_bench.py (download from Marss86 site):
I found that simulations are blocked after first benchmark reaches the
instructions limit. It looks run_bench.py blocks at
# run_bench.py
……
p.wait()
……
And at produced qemu window, it shows
Execution command:
Generic simulation command: simconfig -stats %s.stats -logfile %s.log -run
-stopinsns 10m -kill-after-finish
Chekcpoints to run: ['blackscholes']
All files will be saved in: ./
Running thread with img: ./disks/parsec_image/parsec.qcow2
All Threads are started
Starting Checkpoint: blackscholes
initing the ooomachine
char device redirected to /dev/pts/4
char device redirected to /dev/pts/5
QEMU 0.12.3 monitor - type 'help' for more information
(qemu) loadvm blackscholes
(qemu) simconfig -stats ./blackscholes.stats -logfile ./blackscholes.log -run
-stopinsns 10m -kill-after-finish
simulation options received:-stats ./blackscholes.stats -logfile
./blackscholes.log -run -stopinsns 10m -kill-after-finish
(qemu)
^ infinite wait here.
Did I make some mistakes on running simulation via run_bench.py script? Please
let me know.

Could any share a typical simulation configuration file a multic-core with
cache
configuration for Marss86?
Thanks a lot,
