Topics for discussions:

No agenda yet.

What is a gather control and how to use it.
Is there a way to disable parsec thread binding and use the --map-by ppr:1:socket within OpenMPI to make sure that all the worker threads in a process execute in the same socket?
Using a separate thread to push tasks to an idle process and request tasks when worker threads cannot find ready tasks is a reasonable approach. Does it make sense to merge this with the communication thread? Would it make senseto have this thread bound to the same core as the communication thread
Question about the Haar-tree example: The program is not terminating. Is there any specific threshold and alpha values for this test?

What is prepare_input and how tasks inputs are manipulated in PTG ?
How to correctly release a task ? (even when migrated)
This is not a question but an outcome of the discussion: Can we clean the dependencies tracking before prepare_input ? The idea is that once a task is allocated (which means all input dependencies are available), we do not need the tracking support for the task anymore and we can eagerly release the hash_dep.
