[Wien] LAPW1 doesn't show error in parallel calculation

[Laurence Marks]

Unfortunately the structure of *.error files which are zero length when the
task runs correctly can easily be broken if there is remote
execution/ssh/mpi which does not work. I think in the cases you sent there
is sufficient information to debug; I suspect an issue with directory names
and/or mount.

Suggestion to Peter: perhaps add a "echo Startup Error > lapw1[0-2].error"
in lapw1[0-2]para to catch this?
