INF5063 - Dolphin PCI Express Resources & FAQ

 

Page for resources and frequently asked questions for the Dolphin machines. If you have any other questions, please use the Slack-group.

The following table gives an overview of the status of the lab machines in the lab at Simula. The lab machines are connected two and two with a direct PCIe cable. One setup contains one Intel x86_64 machine, running Ubuntu 16.04 LTS and one Jetson TX1 Development kit running Linux 4 Tegra (L4T) 28.2, which is based on Ubuntu 16.04.

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: No. The two machines in a setup are connected with a direct cable between them. 

 

Q: How can we find the code examples that Dolphin talked about on the lecture?

A: Check the /opt directory of the machine.
