I like these flags but I thought there was going to be a run time
check for cases where Open MPI is built on a system that has ibcm
support but is later run on a system without ibcm support.
Yes, there are.
- if the /dev/infiniband/ucm* files aren't there, we silently return
"not supported" and skip ibcm
- if ib_cm_open_device() (the first function call) fails, we assume
that IBCM simply isn't supported on this platform and silently return
"not supported" and skip ibcm
Right not we are skipping the IBCM all time. Only if user specify IBCM
explicitly via include/exclude interface the IBCM will be used.
