-In a cluster of computers, one has to modify the <tt>forkcolspot</tt> and <tt>forkintegrate</tt> scripts (which are part of the XDS distribution) as shown in [http://xds.mpimf-heidelberg.mpg.de/html_doc/forkcolspot_cluster forkcolspot_cluster] and [http://xds.mpimf-heidelberg.mpg.de/html_doc/forkintegrate_cluster forkintegrate_cluster]. The names of computers called "node1" to "node4" in these example scripts have to be replaced with actual computers names reachable by ssh and having NFS-mounted the relevant directories under the same paths.
+If a cluster of computers is available that allow login - without asking for a password - by <code>ssh</code> and that have NFS-mounted the relevant directories under the same paths, one can use the [http://xds.mpimf-heidelberg.mpg.de/html_doc/xds_parameters.html#CLUSTER_NODES= CLUSTER_NODES=] keyword in XDS.INP.
+If the other computers are not reachable by <code>ssh</code>, but coupled with a batch queueing system, then the forkxds script of the XDS distribution has to be modified: the node names are not relevant, and the <code>ssh</code> invocation has to be replaced by a <code>qsub</code> invocation. An example script will be available soon.
