I’m not familiar with the openib code, but this looks to me like it may be
caused by a change in the openib code itself. Have you looked to see what the
diff might be between the two versions?

Yeah, I forgot that the 1.10 series still had the BTLs in OMPI.
Should be able to restore it. I
t test. Here is the updated output file.

Hi Shiqing!
Been a long time - hope you are doing well.
I see no way to bring the oob module back now that the BTLs are in the OPAL
layer - this is why it was removed as the oob is in ORTE, and thus not
accessible from OPAL.

Ralph,
in v1.10 series, BTL is still in the OMPI layer.
from v2, could the BTL directly use PMIx instead of rml (orte) ?

Dear all,
I noticed that openib oob module has been removed since a long time ago,
because it wasn't working anymore and nobody seemed need it.
But for some special operating system, where the rdmacm, udcm or ibcm kernel
support is missing, oob may still be necessary.
I'm curious if it's possib
