I understand and agree with your point. My initial email is just out of curiosity. Howard tested this BTL for Cray in the summer as well. So this seems to only affected OPA hardware. I just remember that in the summer, I have to make some change in libpsm2 to get this BTL to work for OPA. Maybe

We have too many discussion threads overlapping on the same email chain - so let’s break the discussion on the OFI problem into its own chain. We have been investigating this locally and found there are a number of conflicts between the MTLs and the OFI/BTL stepping on each other. The correct

I already suggested the configure option, but it doesn’t solve the problem. I wouldn’t be terribly surprised to find that Cray also has an undetected problem given the nature of the issue - just a question of the amount of testing, variety of environments, etc. Nobody has to wait for the next

I suspect it is a question of what you tested and in which scenarios. Problem is that it can bite someone and there isn’t a clean/obvious solution that doesn’t require the user to do something - e.g., like having to know that they need to disable a BTL. Matias has proposed an mca-based

Why not simply ompi_ignore it ? Removing a component to bring it back later would force us to lose all history. I would a rather add an .ompi_ignore and give an opportunity to power users do continue playing with it. George. On Thu, Sep 20, 2018 at 8:04 PM Ralph H Castain wrote: > I already
