New user registration
In order to request an account on Centrale Nantes’s supercomputer: Liger, you must have (or be associated to) a Liger project. The flowchart below illustrates the registration process and can help you choose what to do. Sections with more detailed information can be found after the flowchart.
User registration forms
Make sure to have a Liger Project and the associated Liger Project ID (LIPID)*. You will also need:
Send a scanned copy of both documents to email@example.com to request a Liger account.
Liger project request
All accounts need to be related to a Liger project. A project can have multiple users whose compute time (computational hours used) is accounted to the Liger project.
A project is linked to a type of funding. Please refer to the flowchart at the top of this document to understand what projects are available depending on your organisation. Below, a detailed list of all project types:
» To apply for a specific project in one of the categories below, please send an email to firstname.lastname@example.org with project type and description
» For more information on project types, please contact email@example.com
Industrial trial/test projects
They are intended for industrial users who are NEW to ICI-CNSC to allow them to port and test their codes before applying for full project schemes. These projects are generally granted a limited total of core hours over a finite and small amount of compute resources
Industrial paid projects
They are intended for companies or startups to work on research and development topics with private funding. Unlimited resources are granted to these types of projects. It is advised to set a maximum budget as a safe limit to avoid consuming more compute time than the budget allows.
See billing information for payment options.
Academic paid projects
They are intended for academic institutions (such as research laboratories) to use compute time in Liger with private funding. Unlimited resources are granted to these types of projects. It is advised to set a maximum budget as a safe limit to avoid consuming more compute time than the budget allows.
See billing information for or payment options.
Academic “free” projects – Centrale Nantes laboratories agreement
They are intended for projects with R&D Collaborations with ICI and ECN lab partners (internal MCA signed with AAU, LMJL, GeM, LHEEA and LS2N). These projects are generally granted a compute time limit over a finite amount of compute resources. Compute hours are funded by Centrale Nantes’ Research Department.
Academic “free” projects – external laboratories agreement
They are intended for academic institutions (such as research laboratories) external to Centrale Nantes. These projects are generally granted a compute time limit over a finite amount of compute resources. Compute hours are funded by GLICID, a public academic organisation.
Approximate* computing costs:
- industrial projects and startups: 0.05 € – 0.07 € / core-hour
- academic projects: 0.03 € core-hour.
The total amount of compute time for a project is billed at the end of each academic year.
* prices are updated every year and therefore may vary
What is the procedure to open a new account?
Why do I need a project to open an account?
I have some funds for compute time in Liger, how much does it cost?
What are the payment method?
I don’t have any funding dedicated to my project, can I still use Liger?
I am a student / PhD in a lab at Centrale Nantes, can I open an account?
My company wants to try Liger, what can I do?
