The prof2dot tool only knows about the information that is in the
profiling dump file. IIRC,
cost centers are not associated with threads in this file. (The

it is not hard to figure out, given a look at the code that generates
Is recording the thread in which a cost was incurred really helpful?
If it is, I could look into
adding it. But are you more interested in a graphical representation
of thread execution ---
which threads are executing and when? You should check if any of the
Glasgow Parallel Haskell tools are close to what you want. If so, it
might be less
