In Barcelona there's a very special super computer: MareNostrum – according to there homepage the do guided tours. Maybe this would be a cool idea for a side event?
I would be interested! ;)

Finally we decided to go to sincrotó instead , https://en.wikipedia.org/wiki/ALBA_(synchrotron)
Hey Michael, thanks for your proposal! Mare Nostrum is a cool place to visit indeed, but unfortunately we will finally visit another (cool) facility on Friday. However, if you are interested in scheduling a visit to Mare Nostrum (Mo-Fri, 9am-7pm), using the "Self-organised Thursday" etherpad would be a good idea, I'm sure other people will be interested too.
No problem. ALBA is interesting too!
