During December 2025, Bitronic focused on stabilizing and validating CUDA on ROCm test coverage within the pytorch/pytorch repository. They re-enabled the side-stream backward overlap test for ROCm, addressing a longstanding flakiness issue and ensuring the test passed reliably with the latest PyTorch and ROCm updates. Using Python and leveraging GPU programming expertise, Bitronic verified the test on AMD Radeon hardware, confirming correct output and skip handling. Their work improved CI reliability, preserved critical autograd and stream synchronization checks, and strengthened cross-version compatibility. This targeted bug fix supports ongoing ROCm adoption and reduces integration risk for future PyTorch releases.
