SUMMARY:Benesh: a Programming Model for Coupled Scientific Workflows
DESCRIPTION:Workshop\n\nBenesh: a Programming Model for Coupled Scientific
  Workflows\n\nDavis, Subedi, Duan, Ricketson, Hittinger...\n\nAs scientifi
 c applications strive toward increasingly realistic modeling of complex ph
 enomenon, they are integrating multiple models and simulations into comple
 x, coupled scientific workflows. As a result, ensuring that existing codes
  can be combined and recombined correctly and flexibly as part of these wo
 rkflows is essential. In this paper, we propose Benesh, a programming syst
 em for creating in-situ scientific workflows. Benesh provides a domain-spe
 cific abstraction that enables a programmer to instrument an existing simu
 lation code to be used as a building block in composing complex workflows.
  Using Benesh, developers define a workflow-level shared specification of 
 data objects over common or partitioned data domains. This permits depende
 ncy-based execution to be specified at the workflow level, distinct from t
 he independent operation of the component simulations. We additionally des
 cribe features of a scalable runtime that builds on a composed, distribute
 d data services layer to implement the Benesh programming system.\n\nRegis
