Re: [Starpu-devel] Clarification on task graph

[Ankur Sharma <ankur.sharma@mailbox.tu-dresden.de>]

Hello,

Thanks for the response. 
 I have one more query, is it possible to dump the amount of data that flows 
between the tasks. I am trying to label this information on the task graph.

Warm regards
Ankur
