Did you run it on Vega20?

[rkothako]

Yes, we run it on Vega20 also and hence we need Vega20 support. Please add.

[jszuppe]

Sure. Just wanted confirmation it works ok. I'll add it to develop today.

[jszuppe]

Check out https://github.com/ROCmSoftwarePlatform/rocPRIM/tree/develop-gfx906. It will be merged into develop when there's a public release of ROCm with support for gfx906.

Superb...Let me use develop-gfx906 for Vega20 and comeback with observations.

[rkothako]

Thanks @jszuppe ,
I tested on Vega20 with develop-gfx906 branch, tests are running well.
But few failures observed. Looks like issue is due to compiler, but not sure.

91% tests passed, 8 tests failed out of 90

Total Test time (real) = 246.16 sec

The following tests FAILED:
9 - rocprim.hc.block_radix_sort (Failed)
24 - rocprim.hc.device_segmented_radix_sort (Failed)
43 - rocprim.hip.block_radix_sort (Failed)
51 - rocprim.hip.device_merge_sort (Failed)
53 - rocprim.hip.device_radix_sort (OTHER_FAULT)
58 - rocprim.hip.device_segmented_radix_sort (Failed)
80 - hipcub.DeviceRadixSort (Failed)
85 - hipcub.DeviceSegmentedRadixSort (Failed)
Errors while running CTest

We would need more info, but I doubt we can help without environment and gpu.

[rkothako]

Thanks @jszuppe
Looks like issue is NOT specific to Vega20. Its observed in Vega10/MI25 also and we have logged an internal ticket, found to be compiler issue.

[jszuppe]

I'll rebase develop-gfx906 on current develop later today.

Are all of these issues solved, including test 51?
