Hi everyone,

I am trying to install Pardiso on Mac to be used through JuMP but I am a bit lost. I downloaded Pardison from the webpage and I have my academic license key but the file downloaded is “libpardiso600-MACOS-X86-64.dylib”. Do I need to place this file somewhere within my computer or /.Julia folder to be able to get it to work in Julia?

Thanks a lot and sorry if this issue is trivial but the usage manual from Pardiso project has little to non information about the installation process.

Miguel.

As a follow up: this is what I get then I try to run JuMP with Pardiso as the linear solver:

Why is it looking at those weird locations?

Hi @mb96,

I assume you mean you want to use pardiso as the linear solver to Ipopt. You should be able to get it working as follows:

```julia
using JuMP
import Ipopt
model = Model(Ipopt.Optimizer)
set_optimizer_attribute(model, "linear_solver", "pardiso")
set_optimizer_attribute(model, "pardisolib", "/full/path/to/libpardiso600-MACOS-X86-64.dylib")

```

where you replace `/full/path/to` with the appropriate path. For example, `"/Users/miguelborrero/Desktop/libpardiso600-MACOS-X86-64.dylib"` if you placed the file on your desktop.

I need to update the instructions in the Ipopt.jl README. We’re in the process of simplifying things, so hopefully it’ll be a lot easier in future.

Hi @odow,

Thanks a lot for the reply but this is not working. As show below, Julia does not recognize “pardisolib” as a valid option within Ipopt.

Here is how I set the option:

 ![Captura de Pantalla 2022-11-30 a la(s) 08.38.30](https://global.discourse-cdn.com/julialang/original/3X/6/e/6e2719bc335e5869b0eec98662c5f69455773702.png)

Here is the error message:

Are you using a recent version of Ipopt? What is the output of `] status -m Ipopt_jll`?

Try updating your packages.

You need a newer version of Ipopt to use `pardisolib` (a version that shows at least `v300.1400.XXX`; ignore the change from 3.14 to 300.1400, there are just some extra `00`).

Update your packages, and if that doesn’t help, do `] add Ipopt_jll@300.1400`

I did that and still getting the same problem. Here are the new versions:

Nevertheless, it still does not recognize “pardisolib” as an Ipopt option.

You have somehow installed a very old version of Ipopt that is not actually using Ipopt\_jll.

Do you have lots of other packages in your environment? You should use a new environment for each project. Don’t install a bunch of packages into the default environment; bad things can happen like this that lead to version conflicts.

You can work with projects like this:

@odow Thanks a lot Oscar! It is really is a much better practice to do what you said.

I have done it and now I can set pardisolib as an option however I have now another problem:

 ![Screenshot 2022-12-01 at 12.05.14 PM](https://global.discourse-cdn.com/julialang/original/3X/a/d/ade3efebbed29e0ecc62f03a9cf757236b394ca6.png)

Apparently the .dylib file is not compatible with my architecture (I have M1 chip). I believe there’s not much more I can do here because Pardiso does not seem to have a file for “arm64” architecture. Has anyone ran into the same problem?

Use the Rosetta build of Julia. I haven’t tried Pardiso on M1.

Oops. Sure 😄

Download and use the `macOS x86 (Intel or Rosetta)` version of Julia from: [Download Julia](https://julialang.org/downloads/). This should let you use the x86 version of Pardiso.

@odow a quick stupid question: I have now 2 versions of Julia in my applications folder. When I type julia in the terminal it will direct me to the M1 architecture version. Is there a quick way to create a second command (e.g julia\_2) that opens the x86 one?

Consider using juliaup instead: [GitHub - JuliaLang/juliaup: Julia installer and version multiplexer](https://github.com/JuliaLang/juliaup)

@odow Interesting. I have downloaded juliaup and julia x86 but the only versions that juliaup allow me to add are the x64:

The `julia +release~x64` should work with your `x86_64` version of Pardiso.

@odow It does thanks! Now I only need one last thing. It does not found my pardiso license. Where do I have to place it? Currently its in the same folder as the .dylib document. There’s a pardiso.lic file with the license number.
