[Wien] parallel ssh error

[Peter Blaha]

First of all, one of the errors was: lapw1c: command not found

You showed us only the existence of "lapw1", not "lapw1c" with the ls 
commands.

However, since you also have:  fixerror_lapw: command not found

I don't think that this is the problem.

-------------
I'm more concerned about the different usernames/owners of lapw1 on 
different computers.
It is not important who owns $WIENROOT/*, as long as everybody has r-x 
permissions.

However, what is your username and your home-directory on the different 
machines ? It must be the same ! And do you have access to the actual 
working directory ?
In what directory did you start the calculations?
Is it a directory called "Parallel" ? What is the full path of that on 
every computer (/casenode1/Parallel ?)
----------------------

First check would be:

On vlsi1 change into the working directory (Parallel ?) and run one 
iteration without parallelization:   run -i 1

then login to   ssh vsli2 (passwordless), cd into "Parallel" and do 
another non-parallel cycle.  Does it work ?
