Oh, cool! Could you submit an update of the documentation on 

https://files.inria.fr/starpu/doc/html/OfflinePerformanceTools.html#starvz

?

I would say the documentation should advise to add this to .bashrc, and
add $STARVZ_TOOLS to $PATH there too, so that the user just needs to run
starvz at his prompt.

Could starvz optionally directly take a paje.trace file instead of an
fxt file? fxt files are not portable across versions of starpu.

Great :)

Is there an option to generate a "movie" of the matrix tiles
loads/evictions? That would help us with scheduling under memory
constraints.

You could like that paper from the StarPU documentation as well :)
