SUMMARY:shmem4py: High-Performance One-Sided Communication for Python Appl
 ications
DESCRIPTION:Marcin Rogowski (King Abdullah University of Science and Techn
 ology (KAUST), NVIDIA Corporation); Jeff R. Hammond (NVIDIA Helsinki Oy); 
 and David E. Keyes and Lisandro Dalcin (King Abdullah University of Scienc
 e and Technology (KAUST))\n\nWe describe shmem4py, a Python wrapper for th
 e OpenSHMEM application programming interface (API) which follows a design
  similar to that of the well-known mpi4py package. OpenSHMEM is a descenda
 nt of the one-sided communication library for the Cray T3D and it is known
  for its uncompromising performance for low-latency and high-throughput us
 e cases involving one-sided and collective communication. OpenSHMEM is arg
 uably one of the most efficient and portable abstractions for modern netwo
 rk architectures. Thanks to tight interoperability with NumPy, shmem4py pr
 ovides a convenient parallel programming framework leveraging both the hig
 h-productivity NumPy feature set and the high-performance networking capab
 ilities of OpenSHMEM. This paper discusses the design and performance char
 acteristics of shmem4py in a variety of communication patterns relative to
  lower-level languages (C) as well as MPI and mpi4py.\n\nTag: Accelerators
