[Wien] Error in parallel execution

Hi Laurence,

I am not running mpi, only using rsh/ssh for the plain k-point
parallelization. I couldn't really figure out how to make a .machines file
to run parallel over k-points on mpi, with one processor per machine.

However, I think Stefaan's tip has gone right to the point: in my job error
file I get the following errors:

 LAPW0 END
.machinetmp222: No such file or directory
bash: line 0: cd: /afs/atc.unican.es/u/m/mverissi/WIEN2k/sro1sto6:
Permission denied
 Cannot open error-file
ERRFLG - couldn't open errorflag-file.

The fact that from inside lapw1para the ssh command cannot cd to my home
directory puzzles me... it seems to be a system problem, then. However, if
you have any suggsestions, they will be more than welcome!

Thanks,

Marcos
