Hi Durga, Here is a short summary: PSM: is intended for Intel TrueScale InfiniBand product series. It is also known as PSM gen 1, uses libpsm_infinipath.so PSM2: is intended for Intel’s next generation fabric called OmniPath. PSM gen2, uses libpsm2.so. I didn’t know about the owner.txt missing. I’ll look into that.

Any pointer to more information is appreciated. Also, the PSM2 MTL does not seem to have a owner.txt file (on master, at least). Why is that? Thanks Durga We learn from history that we never learn from history.
