Hi Jakob,
Thanks for the heads up.
I selected the Cologne network. I rebuild sumo.exe, sumogui.exe, and
netedit.exe, with AVX2 enabled (my computer's CPU only supports AVX2).
I used Visual Studio 2019 C++ compiler version 16.10.
It seems - with AVX2 enabled, SUMO was getting slightly SLOWER (! about
1% slower), compared to the standard public release.
I didn't tested the SSE, nor AVX512.
Admittedly, this is not a very rigorous benchmarking. But 1% slower was
still a surprise. I guess the SUMO computation is not very
floating-point-intensive?
I will continue with SSE and AVX512 (need to find a supporting CPU
though).
P.S. What is the compiler used for the original SUMO's public release on
Windows platform? MSVC, Clang, or Mingw?

Subject: Re: [sumo-user] Looking for a large SUMO network for
benchmarking
Hello,
There are public scenarios for download at
https://github.com/DLR-TS/sumo-scenarios
The biggest one is brunswick (run brunswick/miv/build.sh and the
brunswick/miv/oneshot.sumocfg)
Larger larger scenario can be found here:
https://sumo.dlr.de/docs/Data/Scenarios.html
If you need even larger networks, download the country of your choice
at http://download.geofabrik.de/ and import with netconvert.
- import: https://sumo.dlr.de/docs/Networks/Import/OpenStreetMap.html
- random traffic should be enough for benchmarking:
https://sumo.dlr.de/docs/Tools/Trip.html#randomtripspy
I'd be interested in learning about your benchmark results.
regards,
Jakob

I have been learning SUMO source code recently, and would like to
thank the SUMO developers for this excellent open-source work.
SUMO is probably the only successful (and enterprise-grade)
open-source traffic simulator that has good performance (native C++),
quality code (both coding and styles), extensive documentation, and an
active user community worldwide.
However, the public SUMO binary release does not have AVX2/AVX512
enhance instruction set enabled.
Thanks to the availability of all sources and dependencies, I was able
to make a special build (on Windows platform) that has AVX2 /AVX512
enabled. I would like to do some performance benchmarking.
Is there someone who can donate network file that is LARGE, for me to
use as the basis for the benchmarking?
Thanks in advance.
