Hi Ralph,
I always got this output from any MPI job that ran on our nodes. There seems to
be a problem somewhere but it never stopped the applications from running. But
anyway, I ran it again now with only tcp and excluded the infiniband and I get
the same output again. Except that this time, the error related to this openib
is not there anymore. Printing out the log again.
