For some reason DRT is running with only a few cores (up to 4 it seems) on my gcloud machine. It has been running for a whole day, and each...

Using grt on routability: ![image](https://github.com/The-OpenROAD-Project/OpenROAD/assets/37420320/514ac981-5703-4e76-9aa5-e40c2be2e362) Using rudy with more inflation than master: ![image](https://github.com/The-OpenROAD-Project/OpenROAD/assets/37420320/59c0db58-265c-410f-a53e-e945f34ea700) Current master with rudy and less inflation: ![image](https://github.com/The-OpenROAD-Project/OpenROAD/assets/37420320/0e62d341-c3c0-4333-8603-a760ed0142a2)

> [@eder-matheus](https://github.com/eder-matheus) this is also tracking issues from GPL, so we cannot close this. Hi @gadfort, would mind explaining exactly what you see as an issue concerning gpl?

Something that seems unusual for sky130hd/aes is that it has some placement density hotspots after placement. ![Image](https://github.com/user-attachments/assets/4cd1feaf-dcde-4511-b2be-e5c17bf2c1a8) After my recent GPL modification, where we keep the changes made by RSZ...

Hi everyone. This is what happens on GPL timing-driven placement: during GPL, we call timing-driven based on a list of 6 fixed values of overflow, defined in src/gpl/src/replace.tcl: `set overflow_list...

This issue was solved with PR: https://github.com/The-OpenROAD-Project/OpenROAD/pull/6165 Other PR changes also went together. To implement this functionality without runtime slow downs we changed a vector access from pointers to indexes...

Here there is some images showing placement density before the change (top) and after the change (bottom): https://drive.google.com/drive/folders/1vmZFFemVsjTfid3QStEZ5TrWDtVBwnlY?usp=drive_link Here I did some experiments trying different non-virtual iterations (1, 2 and...

Hi @kareefardi, I see the difference between runs only happens after the first timing-driven iteration. I am not yet fully aware of the implications of the set_wire_rc command from rsz....

This is the PR: https://github.com/The-OpenROAD-Project/OpenROAD/pull/4580. Hi @kbieganski, do you still see improvements in runtime for gpl with MT?

Hi @oharboe, I noticed you disabled routability driven, it should not be a bottleneck anymore because now we use RUDY instead of fastroute. Although, I would expect timing driven to...
