Hi MSCCL++ team,

Do you know if Driver Version: 535.129.03 has a bug that makes AllReduce3 to timeout?

Thanks,

Hmm... not tested based on this version. Azure hpc image using driver 535.86.10 and doesn't have this issue.

Hi @saeedmaleki, is this issue resolved on your end? 535.154.05 is working good on my env.

it definitely still happens, i think this is a non-deterministic bug. NVIDIA couldn't reproduce it either. so maybe we could ignore it for now.

Actually, I can occasionally reproduce this bug. @Binyang2014 @aashaka please be aware.
