Why the pre-check uses so much ram memory? I'm runing it localy and is using 45 Gb of ram

I suspect this is https://github.com/KLayout/klayout/issues/1189

for now almost kill my server

it is apparently fixed in the latest version of klayout, curious if the new precheck that @jeffdi mentioned is using it already?

no idea I'm using the one for this morning

@proppy which version?

klayout upcoming 0.28 (which is not released yet) which has the recent memory fixes: https://github.com/KLayout/klayout/pull/1193

here is the Dockerfile used for the precheck container…https://github.com/efabless/mpw_precheck/blob/main/dependencies/Dockerfile

also curious if the gf180mcu caravel-lite should also be added to the image? https://github.com/proppy/mpw_precheck/blob/main/dependencies/Dockerfile#L78

it would be nice to get this on the platform as well, as I currently have two designs that are OOM'ing there (I have a smaller version submitted as well that's passing as a backup)

@proppy thanks I will try that

@Ivan Rodriguez Thanks! feel free to comment on the PR, if it yield better results.

Yes, It manage to finish correctly and all of the checks pass

@Ivan Rodriguez can you comment in the PR: https://github.com/efabless/mpw_precheck/pull/174 w/ the screenshot? That'd be awesome.

sure

@Ivan Rodriguez yep, @gatecat mentioned something similar.

It looks like we have the same issue with our design - it passes precheck locally but gets killed on platform during FEOL. It would be great if software on platform gets updated prior to deadline, or if we'll have an opportunity to rerun crashed prechecks later.

if possible I'd recommend sending in a scaled down version of your design as a backup

@jeffdi Can these project bypass the online precheck manually? I have the same problem. https://platform.efabless.com/shuttles/GFMPW-0/project/1634 It can pass locally with 64GB memory. But failed online.

@Ruige Lee @gatecat @Ivan Rodriguez reworded https://github.com/efabless/mpw_precheck/issues/172 can you comment on it saying it's also failing on the platform side with your project ID, that way they can have a good proxy of how people are affected.

Done - I've been asking for this for a few weeks now, I know everyone here is super busy but I hope something can still be done for these projects.

If precheck passes locally we can still accept the project. Please add a message to your project submission. Thx.

Thanks, I will run it again today to double check and then do that

Great!

Do submit the precheck based on your final commit on the platform still. We will need it for the final tapeout.

perfect, great!
