Technical consideration

We can consider large installation like a constallation of simple farms (see Fig. 2).

However before realization of the large farm we should create pilot relatively small experimental Batch Computing Farm (see Fig. 1).

There are several technical questions which may be mentioned now:

• how to maintain and load one OS version in every computer;
• how to use one (or two) keyboard and monitor for a hundred computers;
• how to display the status of the whole large farm in compact and consistent manner.

It is possible to continue this list however those technical details will be solved later because good part of them are already solved in a range of previous projects (FNAL: computing farm, DESY: Hermes PC Farm, etc.). We also have to take into account that new equipment, software, prices are appeared every month.
