Longer jobs, such as those with a duration exceeding 48 hours, should consider using [[Points_de_contrôle/en|checkpoints]] if the software permits this. With a checkpoint, the program writes a snapshot of its state to a diskfile and the program can then be restarted from this diskfile, at that precise point in the calculation. In this way, even if there is a power outage or some other interruption of the compute node(s) being used by your job, you won't necessarily lose much work if your program writes a checkpoint file every six or eight hours. | |||
