HEPiX IPv6 Working Group - in person - Barcelona, Spain

Agenda is very much draft at this point - we may wish to add topics and/or move them around.  Timing of coffee breaks and lunch etc are not yet fixed and may change significantly.

 

We also need more logistics guidance from Pepe.  For example, should we plan to stay in a hotel near to PIC or do we stay in the centre of Barcelona and travel by train each day?

We will meet in person at PIC in Barcelona, Spain

Port d’Informació Científica
Edificio D, Campus UAB, Carrer de Can Magrans S/N,
E-08193 Bellaterra (Barcelona), Spain

(On the UAB Campus)

All agenda times are quoted in local time (CET). The start and end dates and times are definite.  The details within the agenda may still change.
