I am posting this for general information only. In some cases (rare) the mpi versions of Wien2k can hang forever when ssh is being used as a launcher because one of the ssh process has become a zombie. This can occur with impi and mvapich, perhaps others as well.
One reason (there may be others) is a hardware problem, in the case I can reproduce a heating problem on one node, which showed up in /var/log/messages. The actions taken by kernel left the ssh connection as a zombie, and it appears that current mpi versions do not trap this. --------------------------- Professor Laurence Marks Department of Materials Science and Engineering Northwestern University www.numis.northwestern.edu 1-847-491-3996 "Research is to see what everybody else has seen, and to think what nobody else has thought" Albert Szent-Gyorgi
