Dear Prof. Blaha  and Duy Le

Thanks for your help, but I found modifying "lapw1cpara" and "lapw1para" 
scripts by hand, they can work properly for me.

set useremote   = 0             # using remote shell to launch processes

set delay       = 1             # delay launching of processes by n seconds

Thanks once again

> First about "security":   You should NOT run ieN2k as user "root".

> root is the system administrator, and one should be root ONLY when doing 
> sysadmin tasks.
> Create a "regular" user and run "normal work" as restricted user.

> k-parallelization has 2 options during siteconfig:

> "shared memory" machine: This does NOT use ssh to span the parallel jobs, 
> but simply starts eg. 4 lapw1 jobs (in "background") on the local machine. 
> This is the most simple option when you have eg. a single quadcore PC, but 
> you cannot parallelize between 2 different PCs.
>
> "no shared memory": It will use a command like
> ssh pcX  lapw0 lapw0.def ...
> to start a job on a remote but also on the local computer.

> password. For setup of this you must use ssh-keygen, for details see eg.
