If abacus4 has to be powered down for maintenance, only those jobs for which so-called checkpointing is active can continue to run after the interruption of service. All other jobs will be terminated and will have to be restarted.

In order for a checkpoint of job to be created, the job script must simply contain the following line:

   # @ checkpoint = yes

Checkpointing is automatically enabled for GAUSSIAN jobs which are started via the following scripts:
  • subg98
  • subg03
  • subg09
In these cases, no further action is necessary.
