for the (new) fast feedback system (psffb).

Online and offline analysis

Two analysis infrastructures comprising of various queues and interactive nodes, are available to use depending on the status of the experiment.

Online analysis

Ongoing experiment are generally using the online analysis infrastructure, the fast feedback system (ffb). More info on the system here: Fast Feedback System

This system is faster and provides prioritization to ongoing experiments. Some time after the experiment is over, the access to the data will be locked and only the offline system will be available.

Offline analysis

After the experiment is over, the data and smalldata production code are moved to the offline system, the anafs. This system available for analysis indefinitely and can be used to reprocess or refine the data processing.

Workflow

The analysis is generally split in two steps, allowing for easy diagnostics and customization of the analysis process. Please contact your controls and data POC to assess the best approach for your experiment.
