Access to LUMI¶
To access LUMI, you need to be a member of a project that has been granted resources on LUMI. The LUMI consortium countries have different policies for accessing LUMI. An overview of the access policies is provided on the LUMI Supercomputer Get Started page.
In general, a Resource Allocator (RA) must create a project and invite the Principal Investigator (PI), i.e. the lead researcher and members to the project. If you have been granted access to LUMI but didn't receive an invitation to a project, please 1) see also your spam folder, 2) contact your PI or your local organization RA. You may find contact information for your local organization on the LUMI Supercomputer Get Started page.
Once you have received an invitation to a project on LUMI, you need to register with following the instructions that are specific to your access method. The invitation email contains instructions how to proceed.
The recommended authentication method is to use your home organization's identity provider, unless specified otherwise. According to LUMI Terms of Use you must use your institutional email address.
Please note that when using LUMI, you must accept and adhere to the LUMI Terms of Use.
Depending on access path there are different allocation portals for managing the project. Please see the more detailed guidance specific to your access method (besides the invitation email) in the Access guide column from the table below.
