INF5063 - Dolphin PCI Express Resources & FAQ
Page for resources and frequently asked questions for the Dolphin machines. If you have any other questions, please send an email to inf5063@ifi.uio.no
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, and the setup of the hardware is the same as on previous home exams with Ubuntu 12.04 LTS.

Please note that only one person in a group may reserve a timeslot (max 4 hours) at a time! The reason for this is to allow other user access to the processing machines as well. Groups can share the two I/O machines (halvorsen & storage). Try to be only one group per processing machine (mpg-2014-xx). We have a reservation system in place for the GPU machines here at Simula:

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: Share the I/O machines! However we do not recommend multiple groups on the processing machines.
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: Can we assume that the node IDs are static?
A: You can for the I/O machines (halvorsen.ndlab.net is always node ID 4 and storage.ndlab.net is always node ID 8), but not for the processing machines.
Q: How can we find the code examples that Dolphin talked about on the lecture?
A: Check the /opt directory of the machine, you’ll find the Dolphin driver installed on the machines:

Copy this to your users directory and execute it with the --get-tarball option.
This will generate a tar with source. In this tar, the example and benchmark programs are located in this directory: DIS/src/SISCI/cmd/test
