Install MPI.jl

git clone https://github.com/JuliaParallel/MPI.jl

Read https://juliaparallel.github.io/MPI.jl/stable/configuration/ or run the following and hope for the best:

julia --project -e 'ENV["JULIA_MPI_BINARY"]="system"; using Pkg; Pkg.build("MPI"; verbose=true)'

Run stuff

This is trivial, because this program doesn't use MPI.jl:

MPI.jl/bin/mpiexecjl --project=MPI.jl -n 1 julia nstream.jl 10 1000000
