## How to Set the Environment Variable in Juno

In order to set the Environment Variable in Juno one could do:

1. Create a Launcher for Juno  
One could create a script file or batch file to launch Juno and set the variable. For instance, In Windows, see the launcher defined in [Guide: How to Create a Portable Julia Pro Installation for Windows](https://discourse.julialang.org/t/29831).
2. Edit the Init File of Juno
  - Open the Command Pane (`Ctrl + Shift + p`).
  - Type `Init Script` and choose: `Application: Open Your Init Script`.
  - A file named `init.coffee` or `init.js` will be opened. Add `process.env["MKL_DEBUG_CPU_TYPE"] = "5"` in its last line.
  - Save and restart Juno.
