[Wien] make-ubuntu-as-kpoint-parallel

[Peter Blaha]

The machines file should contain only lines with

1:lot

and you can test it by:

ssh lot

and you should login again WITHOUT a password.

PS: If you just want to run on your local laptop, specify "shared 
memory" during siteconfig.
Then you don't need ssh.

PPS: A laptop has usual a rather slow memory bus (maybe except when it 
is a I7 processor). So for sure it is better to set OMP_NUMB_THREAD to 
2. You will then always use 2 cores for a single job and eventually, you 
may use a 2-way k-point parallel setup.
