The computing grid
CC-IN2P3 is a Tier-1 site belonging to the WLCG computing grid; it provides in this context a set of computing resources for those user communities.
If you are registered with a “Virtual Orgnization” (VO) recognized by the computing grids for which CC-IN2P3 is a partner, then you can use all or part of those services.
In case you own a computing account at CC-IN2P3, you can also use the interactive servers as a “User Interface” (UI) woth the grid.
For more details, please refer to the official documentations:
In case of question or problem, please contact our user support.
Access to resources
To use the computing grid you must connect to a UI, belong to a VO and own a valid certificate.
If you own a computing account at CC-IN2P3, you can connect to the grid from the interactive servers which provide the grid tools such as gLite, SRM…
To obtain and manage a certificate, please refer to the page Personal certificates
DIRAC Middleware
CC-IN2P3 hosts the DIRAC middleware instance within the framework of the EOSC European collaborations, providing grid services for several VO.
For more information on this service, please refer to the DIRAC Documentation.
