human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "investigating the ops intermediate representation to target gpus in the devito dsl"):
  Abstract: The Devito DSL is a code generation tool for the solution of partial differential equations using the finite difference method specifically aimed at seismic inversion problems. #R##N#In this work we investigate the integration of OPS, an API to generate highly optimized code for applications running on structured meshes targeting various platforms, within Devito as a mean of bringing it to the GPU realm by providing an implementation of a OPS backend in Devito, obtaining considerable speed ups compared to the core Devito backend.

Includes members:
  Member "architecture and performance of devito a system for automated stencil computation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "devito v3 1 0 an embedded domain specific language for finite differences and geophysical exploration")
  Member "devito an embedded domain specific language for finite differences and geophysical exploration":
    also connected through other hyperedges:
