 This is hard to explain. It all started as a joke. In our lab slang we use the word "raspini" (which has no real meaning in Italian) for referring to the Raspberry Pi. This word sounds very similar to a dialect word (raspèin) that is used in the Italian region in which we work to identify something  that is stuck the throat, In other words, it is an irritated throat... and often the first symptom of a cold.
-=== When will the cluster be operational? ===
+=== Is it possible to visit the raspèin cluster? ===
+The raspèin cluster was 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. <fc #dd3333>**At the end of 2018, the cluster has been dismantled.**</fc>
+=== The Raspberry Pi CPU is not as powerful as a desktop CPU. What is the reason for building a cluster of them? ===
+We were mainly interested in the scalability of distributed algorithms/mechanisms and in the design of fault-tolerant protocols. In other words, the CPU speed was 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 was preferable to a small number of powerful ones.

-As soon as possible, We hope the complete the building and testing phases in the first months of 2013.
