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 in a switch config, the machines run a Intel x86 64-bit architecture, and the operating system is Ubuntu 16.04 LTS.

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. In the current setup, all nodes are connected over a 8-port Dolphin IXS600 PCI Express Switch.
Q: How can we find the code examples that Dolphin talked about on the lecture?
A: Check the /opt directory of the machine.
