- This is a sample 3D stencil application (here just using the game of life rules
- for simplicity), split on the z axis.
- This is a suggest order of read:
- life.c
- life.cu: Heart of the stencil computation: compute a new state from an old one.
- shadow.cu
- shadow.h: Perform replication of data on X and Y edges, to fold the domain on
- itself through mere replication of the source state.
- stencil.h: Declarations
- stencil-kernels.c: Computation Kernels
- stencil-blocks.c: Manage block and tags allocation
- stencil-tasks.c: Schedule tasks for updates and saves
- stencil.c: Main application
- *.out: various results according to beta value (communication vs computation
- penalty ratio), run make pics or make view to get pictures.
- mpi.out: results on MPI.
- results: a few results
- You can also use the implicit distributed flavour of this application (e.g.
- with communications between processes automatically inferred by StarPU-MPI),
- which is called implicit_stencil.
