This is a part that I'm having trouble understanding.

The paper mentions distributing data to different directories (in 6.2.),
but not whether the experiment was done with that or not.
Are the measurements taken with applications writing data to the same
directory or a different directory for each application/node or was the
whole thing done with Swift?
