Is it possible to run fiber on OpenPai ? about fiber HOT 3 OPEN

Hi @tomjamescn, that's an interesting platform from Microsoft. Personally I haven't used it before but seems that it won't be too hard to create a backend to it. I check the document, it has APIs to submit a job, get job status, and start /stop job, which is exactly what's needed by fiber. Would you be interested to contribute a new OpenPai backend? You can follow this example https://github.com/uber/fiber/blob/master/fiber/kubernetes_backend.py . I can provide help along the way.

@calio thanks for your response, I have much interesting to contribute a openpai-backend, I would try.

I have a problem that how fiber deal with communication between master and worker process, I found no config about port for communication. As I know, I could give head and node the port config in Ray.

By default, Fiber master will pick a random port to listen and workers will connect to that port. See ipc_admin_master_port in https://uber.github.io/fiber/config/. If there is a specific port you want to use, you can set ipc_admin_master_port.
