Hi,

who knows that can we use **MPI.jl** for **Julia 1.1.0** (no error, no bug)

Best!

I’m not sure I understand the question - are you saying that you have trouble using `MPI.jl` on Julia 1.1.0? If so it’d probably be helpful if you could produce an MWE that illustrates your problem.

After install MPI.jl

then

```julia

using MPI
mpirun -np 4 julia testone.jl
ERROR: syntax: extra token "4" after end of expression

```

You appear to be typing a shell command into Julia.

```julia
To run a Julia script with MPI, first make sure that `using MPI` or `import MPI` is included at the top of your script. You should then be able to run the MPI job as expected, e.g., with

`mpirun -np 3 julia 01-hello.jl`

```

How in Win10?

`mpirun -np 3 julia 01-hello.jl` from the command line (not julia).

the problem is terminal shows me that it’s running under 1 processor CPU, which has to **be 4.**

Code

```julia
import MPI
include("02-broadcast-impl.jl")

# need to also import Distributed to use addprocs()
using Distributed
function main()
    MPI.Init()

    do_broadcast()

    MPI.Finalize()
end

main()

```

```julia

------------------------------------------------------------------------------
 Running on 1 processes
------------------------------------------------------------------------------
[00] A:Complex{Float64}[1.0+2.0im, 2.0+4.0im, 3.0+6.0im, 4.0+8.0im, 5.0+10.0im]
[00] B:Dict("foo"=>"bar")
[00] f(3):14

```

How can I solve this problem in Julia 1.1.0?
