 === When will the cluster be operational? ===
-As soon as possible, We hope the complete the building and testing phases in the first months of 2013.
+We are currently testing and tuning the cluster.
-=== The Raspberry Pi CPU is not as powerful as a desktop CPU. What is the meaning of building a cluster? ===
+=== Is it possible to visit the raspèin cluster? ===
+The raspèin cluster is on public display at the [[http://corsi.unibo.it/Laurea/IngegneriaScienzeInformatiche/Pagine/default.aspx|Corso di Laurea in Ingegneria e Scienze Informatiche]], Via Sacchi 3, Cesena.
+=== The Raspberry Pi CPU is not as powerful as a desktop CPU. What is the reason for building a cluster of them? ===
+We're mainly interested in the scalability of distributed algorithms/mechanisms and in the design of fault-tolerant protocols. In other words, the CPU speed is not our main concern, but the number of interconnected devices is. Therefore, for our specific use cases a large number of cheap and slow devices is preferable to a small number of powerful ones.
