> 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 - *

> 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
