A page for resources and frequently asked questions for the Jetson AGX Xavier machines. If you have any other questions, please send an email to?in5050@ifi.uio.no
Remember that you might need to SSH into login.ifi.uio.no to access the IN5050 login machine (roa.sinlab.eu). Students from a previous semester created this guide on setting up SSH and SSHFS on external machines. The guide is still valid. However, you might have to change some hostnames/IP addresses.?
A username and password have been provided to all groups. The following table gives an overview of the status of the?ARM machines with a GPU at IFI:
| Computer | GPU | GPU Core | Memory | Multiprocessors (CUDA Cores) | Compute Capability | Status |

Frequently Asked Questions
?
Q:?Can I use my own GPU?
A:?Yes, you can. However, we do not recommend this. The program has to compile and run on the Jetson AGX Xavier Development Kits. Your CPU code should be optimized for 64-bit ARMv8.2, and the GPU code should be optimized for the Volta architecture (Compute 7.x).
?
Q: Do we have any video source files to test with??
A: The video source files are stored in /mnt/sdcard.
?
Q: My video is broken, are there some tools to analyze the video?
A: Yes, there are! Try out YUView, an open-source, cross-platform YUV player and analysis tool.
?
Q: What software do I need if I want to run on my own?GPU?
A: Here at IFI, we are running Ubuntu 20.04 LTS (ARM 64-bit) with CUDA 11.4 from NVIDIA. You have to download both a CUDA-certified driver and the CUDA 11.4.4 toolkit from NVIDIA. The CUDA SDK is optional, but it contains several useful?functions.
?
Q: Are there any differences between the GPU on a Tegra, and a GPU connected with PCIe (dGPU)?
A: Yes! This is something you should be aware of, especially when writing code to transfer data between the host (CPU) and device (GPU) on the Tegra. The integrated GPU (iGPU) shares the memory with the CPU. This application note explains some crucial differences.
