Accelerating solutions of one-dimensional unsteady PDEs with GPU-based swept time–space decomposition

•A GPU implementation of the swept time–space decomposition rule is presented.•Three versions of the scheme are considered.•The shared-memory implementation outperforms the other versions.•The best swept scheme outperforms the classic method by 2–9 times. The expedient design of precision components...
