1 week ago I don't see anything obviously wrong with your setup. It looks all correct.
The logs suggest perhaps some networking issues. The fact that it generates some tokens then stops also confirms a network issue. What network are you running on? What's the bandwidth / latency / jitter between devices like? Can you try pinging or running a small network test with iperf3

1 week ago Hi Alex! Thanks for the reply.

Cool, that's good to read. As a side question, I assume the "0TFLOPs" for the two Linux nodes there is not too important then?
What network are you running on?
It's a regular LAN, and the boxes are all connecting via wifi (5ghz). My router is a Synology rt2600ac, all nodes are connected to the same wifi network.
Let me know if you need more info about it or the nodes.
Can you try pinging or running a small network test with iperf3
I didn't know about this tool. I'll try it out and report back the results.

1 week ago I ran iperf3 as a server in my Mac M2 and then spun up a client from the Quadro RTX5k machine:

iperf Done.Do you see anything off? Let me know if you need more data.
Thanks!
I have a cluster with 3 machines:
I still couldn't get the Linux nodes to show their TFLOPS, it's still showing as 0 (zero), but it doesn't seem to be related to the issue (though maybe I'm wrong?). AFAIK, nvidia-cuda is installed and working (via
nvidia-cuda-toolkitapt package, I'm using the v560 (open) driver from nvidia).I'm trying to run Llama 3.1 8B. As soon as I open tinychat in any of the nodes and start typing with Llama 8B selected, after a while RTX 5000 node fails with:
Then the RTX 4000 node fails with:
And finally, here's the log for the M2 node:
I often only get the first few chars of the LLM answer and then it stops.
Any ideas on why these are failing? All nodes are using the
2b9dec2. I'm using python3.12 on all systems and I'm activating the venv before starting it. On the Linux systems I start it withCUDA=1 exoand on the Mac system withexo --inference-engine tinygrad.Thanks in advance!
