Does 'argobots' provide a mechanism to track dependencies between tasks?

[HPC4AI]

Hi, I want to build a simple runtime system using 'argobots' as the low-level threading library. Typically, a runtime system that supports task-level parallelism uses a DAG to form a program. Nodes in a DAG mean tasks and edges mean dependencies between tasks. Does 'argobots' provide a mechanism to track dependencies between tasks?

Thanks for the question.

Argobots does not provide such a mechanism if you are talking about OpenMP task depend, for example. Argobots currently only supports a Cilk-like divide-and-conquer-based fork-join model. Perhaps more complicated task dependency could be implemented by ABT_Eventual, but at least Argobots does not natively implement it at present.
