IN5050 - Dolphin PCI Express Resources & FAQ
A page for resources and frequently asked questions for the Dolphin machines. If you have any other questions, please use the Mattermost-channel.
The following table gives an overview of the status of the lab machines in the lab at IFI. The lab machines are connected to a PCI Express switch. The setup contains two Intel x86_64 machines, running Ubuntu 18.04 LTS, and four Jetson AGX Xavier Development kits running Linux 4 Tegra (L4T) 32.6.1, which is based on Ubuntu 18.04.

Frequently Asked Questions
Q: There are some issues with the SISCI API and the PCI Express networks. How do I get in touch with Dolphin?
A: You can get in touch with Dolphin Support at simula-support@dolphinics.no
Q: Can groups share machines?
A: Yes, but make sure to use your group ID when generating the "segment ID." If many groups try to use the same segment ID, you will get a "segment busy" error.
Q: Can all machines talk to each other over PCI Express?
A: Yes. The machines are connected with a PCI Express switch
Q: How can we find the code examples that Dolphin talked about in the lecture?
A: Check the /opt/DIS directory of the machine.
