Hi All,

It appears bug of shown GR3D_PCI with 0% (CUDA_VISIBLE_DEVICES=0 for dGPU) always from tegrastats again on Pegasus with DRIVE OS v5.1.0.0-13431798.
…
RAM 5893/24729MB (lfb 2641x4MB) CPU [41%,40%,36%,41%,42%,33%,89%,41%] EMC_FREQ @2133 GR3D_FREQ 9%@1109 APE 245 MTS fg 3% bg 12% GR3D_PCI % 0% AO@35C GPU@33.5C tj@44C AUX@33.5C CPU@35.5C Tdiode@34.25C
…

Any idea on it or only using nsight for profiling?

Thanks!

Gary

Dear Garywang,
Tegrastats does not support dGPU stats. This is a documentation bug and we are working on fixing this issue.

Dear SivaRamaKrishna,
I still relied on tegrastats by its GR3D_FREQ with CUDA_VISIBLE_DEVICES=0. For dGPU in Pegasus, only Nisght or Nsight Compute is available for it. Is this correct?

Thanks!

Gary
