[Wien] parallel ssh error

The "LANG LC_*" probably only puts just the local language variables in 
the remote environment.  Did you follow the previous advice [1] of 
trying to use "*" to put all variables from the local environment?

That seems to be the main cause of the problem as it should not return 
(blank) but needs to return "/servernode1" as you previously mentioned [2].

Perhaps the message below is a clue.  It you had set the WIENROOT 
variable in .bashrc of your /home/vlsi accounts on each system, you 
likely have to login and use that same /home/vlsi account on the head 
node as the output below seems to indicate login to a different 
/home/niel account. Alternatively, setting the WIENROOT variable in 
.bashrc of all /home/niel accounts on each node might work too.

Since it seemed to be throwing an appropriate error message with TASKSET 
previously unlike when set to "yes", probably you should change it back 
to "no".
