[AI Supercomputer] EdgeXpert Related FAQs of NVIDIA Limitation

1. EdgeXpert Bluetooth headset cannot connect.

This is a known issue by NVIDIA. The cause is that the system has the nvidia-disable-bt-profiles package enabled by default, which disables certain Bluetooth profiles, resulting in the Bluetooth headset being unable to connect properly or use audio functions.

This issue is expected to be fixed in the NVIDIA OTA1 update scheduled for November. Meanwhile, users can temporarily resolve the problem by running the following command:

apt purge nvidia-disable-bt-profiles

2. My application is experiencing memory issues even though I am within the memory capacity of the EdgeXpert.

The EdgeXpert uses a unified memory architecture, a powerful architecture that allows for dynamic memory sharing between the GPU and CPU. Many applications are still updating to take advantage of this new architecture.

If you experience memory issues, despite being within the memory capacity of the EdgeXpert, you can check if some memory is being held in the cache by running the free -h and checking the buff/cache field. If you see memory is being stored in cache, you can resolve this issue by flushing the buffer cache manually:

sudo sh -c ‘sync; echo 3 > /proc/sys/vm/drop_caches’
