Grid administration schedule

If you experience problems using Grid'5000, please check the grid administration schedule, where past, present and future incidents (planned or not...) are notified for all sites.

Note that as far as possible most of the administration operations are planned on thursday mornings.

Other monitoring tools are also available (see below) to help you trace your experiment. If you still have questions, please report your problem or contact the technical staff from the most relevant site (or the whole technical committee for global cases).

Ganglia

Ganglia provides information about resources usage (memory, cpu, jobs...) for individual sites or the whole grid.

OAR and OARgrid

OAR is the grid scheduler, which may also be queried for current and planned jobs and nodes reservations, either from command lines (see OAR documentation) or as web services.

Monika

Monika displays current and scheduled jobs. It is possible to view a global snapshot or select an individual site:

DrawOARGantt

DrawOARGantt displays past, current and scheduled jobs. It is possible to view a global Gantt Diagram or select on an individual site:

GridPrems

GridPrems is an alternate grid scheduler running on certain sites.
