The reason for this decision was to make things more uniform.
MON in this case is short for Monitoring. Previous to LCG-2_6_0, this
only contained the R-GMA server. However, it would makes sense to move
the GridIce server here too and reduce the load on the SE. This will
give us a more uniform structure.
CE is the interface to the batch system.
SE is the interface to the storage system.
MON is the interface to the monitoring system.
The default Yaim configuration now does this, however as usual it is up
to sites to choose. Some sites will run all services on one node,
others run them on separates nodes. An example is the site BDII. By
default this is installed on the CE but some sites chose to install it
on a separate node.
