[Wien] x lapw2 -p asking for password to nodes

[Peter Blaha]

You got:
*calculating QTL's from parallel vectors*    !!! ????

If I understand the message correctly, it happens ONLY ?? when you 
calculate the qtls, not during scf.

So your command is either   x lapw2 -p -qtl  or you have QTL instead of 
TOT (FOR) in case.in2  ???

In "qtl" mode, lapw2 runs actually always in single (sequential) mode, 
the -p is used only to indicate that it should use the parallel vectors, 
not the sequential vector.
And before lapw2 actually states, it executes a vec2old_lapw command to 
collect all parallel vector files.

Maybe here is the problem, because vec2old uses
set remotecp = scp
and most likely on your cluster scp is not allowed.

Edit vec2old and put in the proper remote copy command for your cluster.

If this does not help, put a -xf in the first line of lapw2para (and 
vec2old), which gives you a long output, but from that you can follow 
what commands are actually executed and where the problem is.
