PantherLake UH NPU Burnintest issue

[bryant_ou@ibase.com.tw]

When verifying the NPU using Burnintest 11 (1024) at Panther Lake UH, the loading rate is not always at 100% and sometimes drops to 0%.
OS:Windows 11 24H2
CPU Intel Ultra 5 338H
NPU Driver verison 32.0.100.4509

Are you only running the NPU test by itself?
Are you running it at 100% duty cycle?

Yes
Only NPU Test
running it at 100% duty cycle

[Richard (PassMark)]

For the Inference Test, each Cycle of the NPU Tests runs for at least 10 seconds and at least 100 iterations per model (currently only MobileNetV2, additional models may be added in the future). Between each loop, in addition to any delay for the chosen duty cycle, there is setup time though (i.e. load the model and input tensors), but the setup delay should be fairly short.

Is the NPU test correct?

[David (PassMark)]

We don't really understand the question.

We think it is working as designed, based on the information provided, if that is what you mean.

Hi David, I was verifying NPU functionality. With Loading set to 100%, I checked the NPU usage through Windows Task Manager and found it dropped from 100% to 0%. Is this normal?

[David (PassMark)]

Brief drops are normal as there is a setup time required to program / setup the NPU, and task manager doesn't seem to record this as "load".
