SUMMARY:Lightning Talk - Cppless: Productive and Performant Serverless Pro
 gramming in C++
DESCRIPTION:Lukas Möller, Marcin Copik, Alexandru Calotoiu, and Torsten Ho
 efler (ETH Zurich - Swiss Federal Institute of Technology)\n\nThe rise of 
 serverless introduced a new class of scalable, elastic and highly availabl
 e parallel workers in the cloud. Many systems and applications benefit fro
 m offloading computations and parallel tasks to dynamically allocated reso
 urces. However, the developers of C++ applications found it difficult to i
 ntegrate functions due to complex deployment, lack of compatibility betwee
 n client and cloud environments, and loosely typed input and output data. 
 To enable single-source and efficient serverless acceleration in C++, we i
 ntroduce Cppless, an end-to-end framework for implementing serverless func
 tions which handles the creation, deployment, and invocation of functions.
  Cppless is built on top of LLVM and requires only two compiler extensions
  to automatically extract C++ function objects and deploy them to the clou
 d. We demonstrate that offloading parallel computations from a C++ applica
 tion to serverless workers can provide up to 30x speedup, requiring only m
 inor code modifications and costing less than one cent per computation.\n\
