(Note: Requires Julia >= 1.11)

julia --project -e 'using Pkg; Pkg.instantiate()'

To get the mpiexecjl driver run:

julia --project -e 'using MPI; MPI.install_mpiexecjl()'

Afterwards, put '$HOME/.julia/bin' on PATH, e.g.

export PATH=$HOME/.julia/bin:$PATH

(If you don't want to modify PATH use $HOME/.julia/bin/mpiexecjl directly to run the MPI code.)

If you want to use a system MPI run the following:

julia --project -e 'using MPIPreferences; MPIPreferences.use_system_binary()'

No MPI:

julia nstream.jl 10 1000000

With MPI:

mpiexecjl -n 4 julia --project nstream-mpi.jl 10 1000000
