cascgu:

I tried again and solved the problem. When the compilation stops at 50%, just wait. After about 2.5h, the compilation will continue. Finally, the compilation is completed within 12h. Thank you for your patient help and guidance.


This is still highly unusual as I’ve never seen such a behavior on a proper system (I’ve seen it on a Raspberry Pi, which needed to use its swap heavily, so this was expected).
Could you create a feature request on GitHub for the NCCL update so that we can revisit and check in which release it could land, please?
