Koios Benchmarks Failing With Flat Routing

Open nedsels opened this issue 7 months ago • 1 comments

With flat routing on, seemingly all koios_medium benchmarks fail. There are always some number of overused nodes.

Steps to Reproduce

I have created a new branch with a new regression test that is identical to regression_tests/vtr_reg_nightly_test4/koios_medium, except it includes --flat_routing on as an argument.

  1. Checkout this branch.
  2. Navigate to vtr_flow/tasks
  3. Run ../scripts/run_vtr_task.py regression_tests/vtr_reg_nightly_test4/koios_medium_flat_routing

vpr should fail with exit code 2.

Your Environment

  • VTR revision used: commit 3f2b9e8f2c4acc05cc3ab6884235fd4896777236 (I noticed this bug in earlier commits on the master branch)
  • Operating System and version: Ubuntu 18.04.6 LTS (wintermute)
  • Compiler version: gcc version 9.4.0 (wintermute)
