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.
