Grid'5000 infrastructure now uses OAR Grid2.
OAR-GRID is a tool to reserve some computers from different sites of Grid'5000.
OAR-GRID's principle is very simple, on each wanted clusters a reservation is proceeded (in OAR meanings). If one of them did not succeed then all previous reservations are canceled and also the global operation. An identity number is given by OAR_GRID, so with it you can find all reservation information.
