Hi,

I am trying to use argobots for writing a recursive task parallel program. 

I have taken a very simple recursive task program example, where I am creating a parent argobot task which creates two child argobots tasks and then waits for them by calling ABT_task_free(). When I run this program with one xstream I find that it doesn't terminate. (Code snippet - https://gist.github.com/raghav0307/9252fc7b568bc35baab29bdc9da70618 )

My understanding is that this is because the parent task never yields the xstream to the child tasks, and hence the program gets stuck.

This program terminates when I use argobot threads instead of argobot tasks. Could someone point me to why this is not working with argobot tasks?

Best,

Raghav
