In 1.10.x is possible for the BTLs to be in use by ether ob1 or an
oshmem component. In 2.x one-sided components can also use BTLs. The MTL

The openib btl should be able to run alongside cm/mxm or yalla. If I

for tracking this conversation?
I don't want to be posting big attachments emails on this
list.
Thanks,
Howard

David, thanks for the info you provided.
I will try to dig in further to see what might be causing this issue.
In the meantime, maybe Nathan can please comment about the openib btl
behavior here?
Thanks,
