SUMMARY:TaskTorrent: A Lightweight Distributed Task-Based Runtime System i
 n C++
DESCRIPTION:Workshop\n\nTaskTorrent: A Lightweight Distributed Task-Based 
 Runtime System in C++\n\nCambier, Qian, Darve\n\nWe present TaskTorrent, a
  lightweight distributed task-based runtime in C++. TaskTorrent uses a par
 ametrized task graph to express the task DAG, and one-sided active message
 s to trigger remote tasks asynchronously. As a result, the task DAG is com
 pletely distributed and discovered in parallel. It is a C++14 library and 
 only depends on MPI. We explain the API and the implementation. We perform
  a series of benchmarks against StarPU and ScaLAPACK. Micro benchmarks sho
 w it has a minimal overhead compared to other solutions. We then apply it 
 to two large linear algebra problems. TaskTorrent scales very well to thou
 sands of cores, exhibiting good weak and strong scalings.\n\nRegistration
