9 DML operator test failures consistent across devices with NVIDIA and Intel GPUs are confirmed to be caused by the following shaders:
```
Cast_uint64_emulated_float16_native_accum16_256_Packed4D
Cast_int64_emulated_float16_native_accum16_256_Strided8D
Cast_int64_emulated_float16_native_accum16_256_Strided4D
Cast_uint64_emulated_float16_native_accum32_256_Packed4D
Cast_uint64_emulated_float16_native_accum16_256_Packed4D
Cast_uint64_emulated_float16_native_accum32_256_Packed4D
Cast_int64_emulated_float16_native_accum16_256_Packed4D
Cast_uint64_emulated_float16_native_accum32_256_Strided4D
Cast_uint64_emulated_float16_native_accum16_256_Packed4D
```
Failing tests: (Note that only NVIDIA and Intel fail the following tests. AMD passes these tests.)
