[Wien] problems with ssh/csh (or so) on a cluster

[Peter Blaha]

You should not specify an URL, but just a qualified hostname.

You must be able to do on a terminal window:

ssh hostname     or ssh hostname.domain  (like 
"homer.physik.uni-mainz.de" or whatever the full hostname is)

and get connected without a password.

Please read the UG about parallelization. Your .machines file does not 
make sense. You need at least 2 lines

1:host1
1:host2

to get a 2-node k-point parallelization (on dual or quadcores, host2 can 
be equal host1)

The parallelization of
lapw0: host1 host2      needs mpi !!!
