Frequently Asked Questions
Q: There are some issues with the Dolphin APIs and the PCI Express networks. How do I get in touch with Dolphin?
A: You can get in touch with Dolphin Support the Slack channel.
Q: Can groups share machines?
A: Yes, but when measuring performance, please make sure that inly one group is using the 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.
