Re: [sumo-dev] Question about Hardware Requirement
|
Hi,
I had similar issues as described by Haotian Li with the SSM
device when calculating SSM measures for many vehicles. I had the
impression the number of simultaneous SSM vehicles was more
important in this case but did not do more formal checks. In my
case, I solved it by refining the research question to only enable
the device for certain vehicles (e.g. by type, by route,...)
Best regards
Mirko

Hello,
the SSM device is not very memory efficient and has only
been used on medium sized scenarios thus far.
However, a shutdown of the simulation might also be due to
a software bug (i.e. due to a combination of untested options
or an untested traffic situation).
Does the simulation complete successfully without SSM
device?
Does the simulation complete with SSM device and default
scale value? How much memory does it consume in this case?
How big is the simulation (total number of vehicles,
approximate number of simultaneous vehicles)?
regards,
Jakob
To
whom it may concern:
I
am Haotian Li, a senior student from UCD and BJUT. I'm
here to ask something about the hardware requirement for
sumo-gui. I am working on a summer internship using this
software as a tool. When I tried to simulate the urban
networks using the scale of 3(try to provide traffic
jams), I used SSM devices to detect TTC and PET and
record conflict loading in conflict.xml and do
statistics research after simulation ended. However, I
found that 16G RAM can't afford the stress of caching
index files and it would break down while simulating.
Then, I tried the 32G one and it would also shut down
even if the memory usage is not high. Would you please
give me some suggestions to fix it? Or I may forgive
this scenario because the DDL is approaching. Looking
forward to your reply. Have a nice day!
Yours
sincerely,
Haotian
Li
