Note 2: The raw data are copied to the offline storage system and to tape immediately, i.e. in quasi real time during the experiment, not after they have been deleted from FFB. The users generated data, e.g. the scratch and results folders, are copied to the offline system when they are deleted from FFB.

Note 3: For the time being, the new FFB system will be available only for NEH experiments. FEH experiments will still rely on psana resources.

You can access the FFB system from pslogin, psdev or psnx with:

You can submit your fast feedback analysis jobs to one of the queues shown in the following table. The goal is to assign dedicated resources to up to three experiments for each shift. Please contact your POC to get one of the high priority queues, 1, 2 or 3, assigned to your experiment.

Note that jobs submitted to ffbl<n>q will preempt jobs submitted to anaq and jobs submitted to ffbh<n>q will preempt jobs submitted to ffbl<n>q and anaq. Jobs that are preempted to make resources available to higher priority queues are paused and then are automatically resumed when resources become available.

The FFB system uses SLURM for submitting jobs - information on using SLURM can be found on this page: the Submitting SLURM Batch Jobs page.
