Description

We need to investigate this ticket and likely file an internal vendor issue to get the driver fixed.

Research direction

Start by reproducing the 18 listed OffloadTest-clang-d3d12 WaveOps failures on an Intel B50 GPU. Compare the failing WaveOps tests, including the data-race, active-sum, prefix-product, and prefix-sum cases, to determine whether the failures indicate a driver defect. Done means documenting the cause and filing the internal vendor issue if the driver is responsible.
