I was wondering if it handles per-thread information when you have more than one thread involved. (Actually the question is not related to the graphical tool, but the announcement triggered it).

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 format isn't documented, but

it is not hard to figure out, given a look at the code that generates it.)

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 old

Glasgow Parallel Haskell tools are close to what you want.  If so, it might be less

work to resurrect one of those.
