A Julia interface to the Scotch graph partitioner Scotch can be obtained at https://www.labri.fr/perso/pelegrin/scotch/
To use the library:
- Compile Scotch as a dynamic shared library (.so on linux, .dylib on mac). Scotch is normally compiled as a static shared library (.a). See src/scotch_wrapper.cpp and src/makefile for an example showing how to easily compile Scotch as a dynamic shared library.
- In your ~/.juliarc.jl file, define SCOTCH_SCOTCHLIB to point to the shared library file
- Include Scotch.jl and import Scotch
- Call the routine like you would call Scotch, using the same sequence (alloc/init/use/free/exit).
All function can be used as
import Scotch
Scotch.[scotch function name](arguments)
This is still very experimental and a work in progress See example.jl for an example.
An example of .juliarc.jl file
const SCOTCH_LIBSCOTCH = "[path to]/Scotch.jl/src/libscotch.dylib" # For libscotch.so/dylib to be found at runtime
push!(LOAD_PATH, "[path to]/Scotch.jl/src") # For being able to do import Scotch
