SUMMARY:Evaluation of Distributed Tasks in Stencil-Based Application on GP
 Us
DESCRIPTION:Workshop\n\nEvaluation of Distributed Tasks in Stencil-Based A
 pplication on GPUs\n\nRaut, Anderson, Araya-Polo, Meng\n\nIn the era of ex
 ascale computing, the traditional MPI+X paradigm starts losing its strengt
 h in taking advantage of heterogeneous systems. Subsequently, research and
  development on finding alternative programming models and runtimes have b
 ecome increasingly popular. This encourages comparison, on competitive gro
 unds, of these emerging parallel programming approaches against the tradit
 ional MPI+X paradigm. In this work, an implementation of distributed task-
 based stencil numerical simulation is compared with a MPI+X implementation
  of the same application. To be more specific, the Legion task-based paral
 lel programming system is used as an alternative to MPI at out-of-node lev
 el, while the underlying CUDA-implemented kernels are kept at node level. 
 Therefore, the comparison is as fair as possible and focused on the distri
 buted aspects of the simulation. Overall, the results show that the task-b
 ased approach is on par with the traditional MPI approach in terms of both
  performance and scalability.\n\nTag: Architectures, Big Data, Cloud and D
