The POETS project is a five-year effort to build a combined software and hardware system which allows applications to be split into 1M+ concurrent state machines, and then to execute them on 100K+ concurrent hardware threads across 100+ tightly-coupled compute nodes. To achieve this we use an event-driven compute system with no global barriers or shared state, and re-write applications to use globally asynchronous algorithms. This talk will give an overview of the current hardware that has been built, and show how applications such as finite-volume solvers can be re-cast as an asynchronous system in order to run on such hardware. It will finish with initial strong and weak scaling results for a number of applications running on prototype systems with up to 1024 hardware threads.
