Switching between iGPU and dGPU
The Clara AGX Developer Kit can use either the Xavier AGX module GPU (iGPU,
–
integrated GPU) or
the RTX6000 add-in card GPU (dGPU,
–
discrete GPU). You can only use one type of GPU at a time.
By default, the Clara AGX Developer Kit uses the iGPU. Switching between the iGPU and dGPU is
performed using the
nvgpuswitch.py
script located in the
/opt/nvidia/l4t-
gputools/bin/
directory. To make the
nvgpuswitch.py
script accessible globally, copy it to a
directory included in
$PATH
if it hasn’t been already:
$ sudo cp /opt/nvidia/l4t-gputools/bin/nvgpuswitch.py /usr/local/bin/
To switch from the iGPU to the dGPU, follow these steps:
1.
Connect the Clara AGX Developer Kit to the Internet using one of the following methods:
a)
An Ethernet cable connected to a router or Wi-Fi extender
i)
Use the 1GbE connector to the Xavier module at port 7.
b)
A USB Wi-Fi receiver
i)
Not all USB Wi-Fi receivers will work out of the box on the Clara AGX Developer Kit.
ii)
The USB Wi-Fi receiver should have support for Ubuntu 20.04.
iii)
The TP-Link Archer T2U Nano USB Wi-Fi Adapter, which has previously worked with the
Ubuntu 18.04 Holoscan SDK versions, will no longer work with Holoscan SDK v0.2, which
based on Ubuntu 20.04.
