Error running on Win10

[henry2004y]

Hi,

I have an issue running MPI.jl on windows. In the Julia REPL, first I typed

julia> using Pkg

julia> Pkg.add("MPI")
   Updating registry at `C:\Users\henry\.julia\registries\General`
   Updating git-repo `https://github.com/JuliaRegistries/General.git`
  Resolving package versions...
   Updating `C:\Users\henry\.julia\environments\v1.4\Project.toml`
 [no changes]
   Updating `C:\Users\henry\.julia\environments\v1.4\Manifest.toml`
 [no changes]

julia> Pkg.status()
Status `C:\Users\henry\.julia\environments\v1.4\Project.toml`
  [da04e1cc] MPI v0.15.0

Then I created the same demo script from here:

# examples/01-hello.jl
using MPI
MPI.Init()

comm = MPI.COMM_WORLD
println("Hello world, I am $(MPI.Comm_rank(comm)) of $(MPI.Comm_size(comm))")
MPI.Barrier(comm)

During my first attempt in cmd,

mpiexec -3 julia test.jl

it returned similar as being reported in this issue

User credentials needed to launch processes: account (domain\user) [DESKTOP-3CFSBJ8\Hazem]:

I followed the instructions there

mpiexec -register

and added a user and passwd. Then, for the second attempt,

Microsoft Windows [Version 10.0.19041.388]

What is the exact error here?

Can you try the following:

julia -e 'using Pkg; Pkg.status()'
mpiexec julia -e 'using Pkg; Pkg.status()'

I don't know what the second error is about. Can you put

using Pkg
Pkg.status()

in a file called status.jl and run it with mpiexec -n 1 julia status.jl?

[henry2004y]

Here it is:

Hmm, looks like the permissions are still not set correctly. Unfortunately i'm not familiar with Windows permissions.

Can you use the BinaryBuilder-provided binary? Try setting JULIA_MPI_BINARY="" and rerun Pkg.build("MPI").
