ABSTRACT

Asynchronous Many-Task (AMT) programming models and runtime systems hold the promise to address key issues in future extreme-scale computer architectures, and hence are an active exascale research area. The DHARMA project at Sandia National Labs is working towards three complementary AMT research goals: 1) co-design a programming model specification that incorporates both application requirements and lessons learned from other AMT efforts; 2) design an implementation of that spec, leveraging existing components and expertise from the community; 3) engage the AMT community longer term to define best practices and ultimately standards. In this talk we discuss recent results and current state of the DHARMA project. We highlight our recent comparative analysis study and how it informs our higher-level design philosophy. We introduce features from our developing spec and where that spec fits in the AMT design space. Finally we discuss the effort remaining to achieve a DHARMA Implementation.
