At the recent PyCon Quattro, which took place in early May in the beautiful Tuscan city of Florence, Fabrizio Milo gave a talk on PyCUDA entitled
PyCuda: Come sfruttare la potenza delle schede video nelle applicazioni python (PyCUDA: How to make use of the power of graphics cards in Python applications)
He made a set of rather nice slides (in English), which may be of interest. They are downloadable in PDF form at the link.
Thanks Fabrizio for taking the time to talk about PyCUDA!
