As stated in the manual, you need a "common" filesystem on all nodes
which you want to use in k-parallel mode.
Typically, this involves NFS (or some other "cluster-filesystem", ...).
The key is, that the mount-point must be the same on all nodes, i.e. the
full path to your directory/files must be the same.
Typically one should reconfigure his Linux boxes, because by default all
user-data are in /home and of course all nodes have then their own /home
directory and one cannot use: mount node1:/home /home, because this
would overwrite the /home on the second node.
You could create a directory "/node1" on node1 (and /node2 on the next
node, ...) and mount /node1 on all other machines under the name /node1.
The directory /node1/name should then be also your home-directory on
all these nodes.
Every computer-center / cluster is setup in this way. If you are your
own system manager, you have to do it yourself.

I try to configure the k-paralellization over several PCs connected by a
regular (slow) network. I use w2web, so that commands are transparent to
me.
Wien2k is installed on all machines, and paths are the same on all
machines. SSH works without password on all machines.
Is NFS mandatory with this configuration ?
If so, to which directory should the mounted directory point to ? What
should be its name, and where should it stand on the calling machine ?
Thanks
PS : I hope this message threads correctly: I was told by the archive
manager to replace the addressee from the "reply to' button by Wien's
address (?).
