@kbtxwer, The README.md file was a bit out of date, but I just updated it to match some of the recent changes we made to the LoopPoint code. Thanks for pointing this out. Please do make distclean
and follow the instructions in README.
Thank you very much. I have remake the LoopPoint and run the test script again, however, I still get these following errors, could you help me to figure out what goes wrong again?
in app terminated abnormally due to signal 6.

It seems like an older version of Sniper has been downloaded. Can you go to tools
directory, manually delete sniper
directory, and then go back to the base directory to do make clean && make apps && make tools
? Sniper, if you run the default command, should ideally run the frontend using Intel SDE, but I can see in the log you shared that the frontend is using Pin.
I think I got the sniper v7.4, because I have forked it into my own space to ensure the download speed
Anyway, I will try again and feedback later.
Besides, I think
sniper_args += ['--trace-args="-sniper:flow 1000"']
might be a typo and should replaced with
sniper_args += ['--trace-args="-flow 1000"']

I tried again, but it still use Pin as default frontend.
Here is the latest output: demo-matrix-1-test-passive-8-20220711124043_2.zip
If you see the Makefile in the base directory of LoopPoint, you can see that we have set SNIPER_GIT_REPO?=https://github.com/snipersim/snipersim.git
which should download the latest version of Sniper (v8.0 and not v7.4). Are you modifying this link? For Sniper v8.0, the default frontend is SDE, and there were some changes to the frontend flags (like using -sniper:flow
instead of -flow
etc).

Ah, yes. I have noticed that and re-import the repo after some failed attempts. However, there are some errors which still exist in the last step

I now run it in the docker container.
Still, the full log is attached here. looppoint.log.txt demo-dotproduct-1-test-passive-8-20220711091648.tar.gz.zip
(I am sorry but the error log seems only appear in the terminal)
From the logfile, what I can see is that the representative region specifications are not triggered during simulation. However, support for LoopPoint region specifications were added to Sniper 8.0 and therefore it is not clear why there is an issue. Maybe, start with a fresh copy of LoopPoint (clone from GitHub). You do not need to build the docker image again. Do make
to launch the docker instance; within the instance do make apps
to compile the demo applications and make tools
for downloading and building the necessary tools including Sniper. There is no other intervention required otherwise.
I have clean up and remake apps and tools.
This time, I add some print
scripts in function get_sim_res(config, sim_path, profile_path, region = None)
in run-looppoint.py
, and I got these following messages:

[LOOPPOINT] Error: Simulation results not found for r13
It seems that roi-begin is an invalid prefix, but I don't know what does that mean.
Here is the function I modified:
def get_sim_res(config, sim_path, profile_path, region = None):
print('[GET_SIM_RES] dir %s, region %s' %(sim_path, region) )
if region == None:
return -1
resultsdir = os.path.join(sim_path, region)
try:
res = sniper_lib.get_results(resultsdir=resultsdir)
except (KeyError, ValueError), e:
print('[LOOPPOINT] Error: Unable to fetch results for %s.' % region)
print(e)
if region == 'wp':
exit(1)
return -1
results = res['results']
config = res['config']
return results, config
What's more, I fond all sim.out
files under r*
directory are empty, but sim.out
under wp
directory have contents inside.
Also, when I modify function generate_simout
in gen_simout.py
to print the error information, I got Failed to generated sim.out: Invalid prefix roi-begin
after a region reach to the end, which means it took a long time to execute and give out nothing.
def generate_simout(jobid = None, resultsdir = None, partial = None, output = sys.stdout, silent = False):
try:
res = sniper_lib.get_results(jobid = jobid, resultsdir = resultsdir, partial = partial)
except (KeyError, ValueError), e:
if not silent or True:
print 'Failed to generated sim.out:', e
return

Failed to generated sim.out: Invalid prefix roi-begin
I opened wp/sim.stats.sqlite3
and r13/sim.stats.sqlite3
, and compared each other and found that the table in wp/sim.stats.sqlite3
has 4 records, but the table in r13/sim.stats.sqlite3
only got 2.
I think this is the main problem caused the exceptions above
I rolled back pinpoint to version d0e2e27da9979dea5890226e8bf2f44036ab8d26
and now it seems work well.

Yes, this is what I meant when I mentioned that the LoopPoint region specifications are not triggered during simulation. I will look into what can cause such an issue with Sniper using SDE frontend.

This is the first public version of LoopPoint. If this works, I wonder why doesn't Sniper+SDE combination work. What machine are you running the docker instance on (assuming you run LoopPoint inside the docker instance)?

ThinkStation-P920 Intel® Xeon(R) Gold 6126 CPU @ 2.60GHz × 48 Ubuntu 20.04.3 LTS (64-bit)
I just finished running the latest version of LoopPoint again and am getting it to work correctly without doing anything different from the README. I can share the log file if required. Meanwhile, I am running the docker instance on a Skylake machine similar to yours running Ubuntu 16.04.4 LTS
Hi @kbtxwer and @kbtxwer,
I am facing the same exact problem below. Would you please tell me the steps I should carry out to overcome this problem? I have not modified any file and I just cloned the LoopPoint repo today, July 18.
Thanks.

@abdelrahmanhussein, it seems you are facing the same problem with Sniper not being able to trigger the PC-based region specification. Can you share more details as we cannot reproduce the issue from our side? Perhaps if you can compress and share the setup as a tarball (including one set of output directories), that would allow us to look into it.
Hi, I am having similar issue, fresh installation, do you happen to know how to solve this issue? Thanks

@lzto This seems to be related to a recent check-in to the Sniper repo. We'll look into this to have a fix very soon.
looks like this knob is changed in https://github.com/snipersim/snipersim/commit/d427c8f339c9d22483de927e169be3c0ad6a28a9
changing -control to -pinplay:control solved the issue.
OK -- things are still not right -- Now I am getting the same error

Looks like it need KASLR disabled to run correctly.

Another question to @alenks, what is the software license for looppoint? I saw readme file and other files contains different information. Can you please clarify. Thanks,
@lzto Yes, disabling ~K~ASLR is a workaround to get things working. But we're trying to get another solution to make it work so that it works even when ASLR is enabled (since this is the default case now).
Thanks for pointing out the ambiguity in the software license. When we released the tools initially, the licenses were different for a number of tools that we use. The licenses changed for some of the LoopPoint codes (the licenses are provided in the particular files), Sniper (Academic/MIT), Pin/SDE/PinPlay kits, etc. The driver scripts have an MIT license.
Thank you Alen. I am examining the output of looppoint and some value looks way off For example, the access latency(s) are negative in the simulation/*/sim.out file. Is this normal? Thanks,
DRAM summary | | | | | | | |

@lzto This could be due to how fast-forwarding is handled by the simulator. Note that these results are computed by the gen_simout.py
script. We can look into the Sniper sim.stats*
files (via dumpstats.py
) to see the latency data. I suspect that gen_simout.py
has a bug preventing it from accurately showing results during LoopPoint simulation.
Closing this issue as the approach to use image-name+offset
instead of absolute PC
solves the problem when ASLR is enabled. Please reopen if the issue persists on your machine.
It seems that -sniper:flow shouldn't appear in the commandline, and after which, I got these following messages:
Then, each running command got an end with "Cannot find script file simuserroi"
I wander if the script should be gengrated in the step which reports "unknown option "-sniper:flow" " , and how to fix it?
