ABSTRACT:

Next generation platform architectures will require us to fundamentally rethink our programming models and environments due to a combination of factors including extreme parallelism, data locality issues, and resilience. As seen in the computational sciences community, asynchronous many-task (AMT) programming models and runtime systems are emerging as a leading new paradigm. While there are some overarching similarities between existing AMT systems, the community lacks consistent 1) terminology to describe runtime components, 2) application- and component-level interfaces, and 3) requirements for the lower level runtime and system software stacks. This panel will engage a group of community experts in a lively discussion on status and ideas to establish best practices in light of requirements such as performance portability, scalability, resilience, and interoperability. Additionally, we will consider the challenges of user-adoption, with a focus on the issue of productivity, which is critical given the application code rewrite required to adopt this approach.
