Re: [OMPI devel] RFC: Linuxes shipping libibverbs

[Pavel Shamis (Pasha)]

I got some more feedback from Roland off-list explaining that if /sys/ 
class/infiniband does exist and is non-empty and /sys/class/ 
infiniband_verbs/abi_version does not exist, then this is definitely a  
case where we want to warn because it implies that config is screwed  
up -- RDMA devices are present but not usable.
  
Is it possible that /sys/class/infiniband directory exist and it is 
empty ? In which cases ?
