SUMMARY:Extending the C++ Execution Control Library to Support Dynamic Par
 allel Runtime Systems
DESCRIPTION:Ian Henriksen, Jan Ciesko, and Stephen L. Olivier (Sandia Nati
 onal Laboratories)\n\nThe release of the C++26 execution control library (
 senders and receivers) provides a uniform interface for coordinating async
 hronous work on heterogeneous backends.\nThat said, the standardization of
  senders and receivers is just a starting point toward structured parallel
 ism and composable heterogeneous parallel programming.\nTo evaluate these 
 capabilities, we present a sender-based interface for the Qthreads user-le
 vel threading library.\nIt shows that the execution control idioms apply e
 ven to cases where work is discovered and created dynamically and the degr
 ee of concurrency vastly surpasses available hardware resources.\nHere we 
 provide an introduction to the C++26 standard execution control library an
 d show how it can be used with dynamic runtime systems.\nWe demonstrate th
 at the new standard interface is extensible and motivate future work on si
 milar runtime integration efforts.\nWe show that this interoperability lay
 er incurs low overhead and provides additional optimization opportunities,
  even when used in a fine-grained parallel setting.\n\nRecording: Livestre
