Solvers are available by region. This article explains how to make a simple change in the Leap IDE to submit a problem to a solver in a particular region: eu-central-1.
Note: Not all accounts have access to solvers in all the available regions. Check your Leap Dashboard to see what solvers are available to you.
To submit a problem to a solver by region using the Leap IDE:
- Go to the Resources page in Leap and click the Ocean Code Examples card.
- In the search bar, type qpu. Several code examples that submit problems to the QPU are displayed.
- Hover your mouse over one of the examples; for example, the Structural Imbalance in Signed Social Networks example.
- Click the Load in IDE popup.
- Wait for Leap’s online IDE to open the example in your browser.
- Open a terminal from the IDE’s top-bar commands.
- In the terminal, type the following (note that the second line is specific to the structural_imbalance.py example):
python structural_imbalance.py --qpu
The script submits a problem to the QPU in the eu-central-1 region and returns a solution.
Note: The Structural Imbalance in Signed Social Networks example also creates a graphic file, structural imbalance qpu global.png, that visualizes the solution. Click on the returned file to display the visualization.
Note: By default, problems are submitted to solvers in North America. To return to submitting problems to solvers in the North American region, run the following command in your terminal:
