Nanmur opened a new pull request, #19996: URL: https://github.com/apache/tvm/pull/19996
## Motivation Fixes #19976. `VerifyGPUCode` runs a lowering pipeline while EvolutionarySearch applies postprocessors in parallel. On Windows, concurrent executions of this pipeline can terminate the process during candidate generation. ## Changes - Serialize the `VerifyGPUCode` lowering pipeline on Windows. - Keep the existing parallel behavior on other platforms. - Add a Windows-only CUDA Conv2D regression test that exercises the concurrent EvolutionarySearch path. ## Validation - The regression test terminates with `0xC0000374` before the fix and passes after the fix. - Candidate generation completed 40/40 runs across `num_threads=1`, `2`, `4`, and `physical`. - Related MetaSchedule tests: `16 passed`. - A one-trial CUDA tuning run completed Builder and LocalRunner measurement successfully. -- This is an automated message from the Apache Git Service.
