My bad -- typo -- I meant to say btl_base_debug, not btl_base_verbose.

I was replying to the fact that you said: "In fact, the
debug/verbose code in the btl_base_open.c is such that we can never
turn on verbose messages." I don't think that's a correct statement
because you can "--mca btl_base_debug 100" and get some output.
