16:40 - 17:30 Debate - Moderator: Flavio Vella (Free University of Bozen)
Proposition: "Programming abstractions can greatly simplify the expression of complex workflows of data analytic applications, but make it difficult to customize source code for heterogeneous computer systems. Unfortunately, it is an either or situation --- easy expression or fast performance"
Panelists: Nesreen Ahmed (Intel), Jonathan Beard (ARM), Tyler Sorensen (Princeton University), Ana Lucia Verbanescu (University of Amsterdam)
