Stockfish and Leela Chess Zero Crashing While Running Locally

Hello everyone, I am trying to use computer engines (specifically Stockfish and Lc0) to play against each other in certain positions so I can try to find plans in certain positions. However, these engines keep on suddenly crashing. Does anyone have any tips for how to fix this?

have u tried asking ur coach? @r2d2bb8

I think we need more information. Is this the first time you've installed engines into a GUI? Which GUI? What OS? How long do the engines operate before they crash? What happens when they crash?

You know, more info!

Well, I can run stockfish vs Lco in my desktop and also on my android phone.

This is the screenshot of engine tournment on my phone.

Note. Look at Leela blog for setting up leela.

Note. Smartphone version of Leela is still too weak( Stockfish running 400 kn/s and Leela 0.2 kn/s)

Update, Running speed optimized.

SF is now running on 4645 kn/s and Leela is now running on 0.076 kn/s .

Leela vs Stockfish on my desktop. 

Sorry for late response, this is definitely not the first time I've installed chess engines into GUIs. I am using HIARCS chess explorer. I am using Windows 10 (October update). The engines operate for around 10 minutes before crashing. When they crash, HIARCS gives the error "Stockfish 10 BMI has crashed." Then when I restart the engine it is fine.

Also, just trying to get more info about these forums, but how old must a forum be to be considered dead?

No idea. Hopefully 3 comments within 15 min will bring it back to life

No definitive ideas about the cause of the crashing. Maybe you could try running non-BMI versions to see if the problem goes away. Also, could it possibly be a cpu overheating problem? Do you keep tabs on the cpu temps?

 I can get an idea if you upload log file.( crash report). Otherwise, no idea.

This happens with all the engines that I've tested (Stockfish, Lc0, HIARCS, Laser) so I don't think it's BMI. Also, I can't see cpu temp bc I have a budget laptop. I know it isn't ram because I have 16 GB and my cpu isn't throttling because it is sustaining a clock speed of 3.2 gHz across all 12 cores when the base clock is 2.2 gHz.

Whenever I try to replicate the results, it doesn't crash and I just found out that I didn't have crash reports enabled. I'll send one when I randomly get one.

Yeah, a crash report might be necessary. Even if it's not a temp issue, it's a good idea to monitor the cpu temps. I use Core Temp. SpeedFan will also give basic cpu temp information. There's also a program called Open Hardware Monitor that might work, although I've never used that one.

I finally caught the engine crash in a log. Sorry about the big log size but here is a link to it.

Maybe drmrboss can make sense of the crash log - It's pretty much Greek to me.

At this point, I'd just start trying things. Try a different GUI. Back off on the number of threads (I think the crash log said Stockfish was using 10 threads.) Install either Core Temp or SpeedFan to monitor your cpu temps.

Another idea that just crossed my mind is the possibility of flaky RAM. I'd download a copy of Memtest86+ and check out your RAM. (I think you'll have to make a bootable flash drive containing Memtest86+.)

+1,

It is same as his advice.

You are doing infinite analysis. Arena GUI can also run infinite analysis,

Yeah, the only thing I got out of the crash log is that he was running infinite analysis with the MultiPV set to 3.

@drmrboss how do you do that on android please?

Here is the source, but it has many technical barriers, not user friendly,. And also android leela is too slow . Droidfish is way better.
