Does Vertex mean no reads or write any data in v or in vertexes adjacent to v?

I believe it just limits reads and writes in v itself, I think you're describing scope

What's the difference between "Full" and "Edge"?

@jchao01 In this example, if the atomicity is specified with respect to red vertex, "Full" will provide atomicity on the red vertices, blue vertices, and blue edges; "Edge" will provide atomicity on red vertices and the blue edges. This is around the 37:45 mark of the lecture. (On a side note, shouldn't it be "red vertex" instead of "red edge" in the lecture recording?)

Thanks @awu!
