ArgoBots

"Concurrency in today’s most powerful HPC systems is exploding. As noted in the International Exascale Software Project roadmap (IESP), the future exascale systems are likely to be composed of hundreds of millions of arithmetic units and future applications may contain billions of threads. Computational scientists are adapting their programming models and computational methods for emerging applications. In order to tackle massive parallelism, new programming models will decompose the computational problem into lightweight tasks or threads that can increase concurrency, hide latency, and improve resilience.

Argobots, which was developed as a part of the Argo project, is a lightweight runtime system that supports integrated computation and data movement with massive concurrency. It will directly leverage the lowest-level constructs in the hardware and OS: lightweight notification mechanisms, data movement engines, memory mapping, and data placement strategies. It consists of an execution model and a memory model.

Argobots has been expanding its ecosystem both inside and outside the Argo project. Various programming models are integrating Argobots into their runtime so that their applications can take advantage of Argobots without modifying the code.
