Pipeline ProductsPipeline Products
• 5 Files– LDF
• From Online– Digi– Merit– Recon– SVAC
• 3 Reports– Configuration
• Depends on schema, snapshot (from Online)– Digi
• Depends on digi file– Recon
• Depends on recon, digi files• Put it all on the web
– Enter in eLog DB

ReprocessingReprocessing
• A review is required to decide when to do it– CCB chaired by Richard Dubois
• Reasons for reprocessing– Major software update (EM package, Calibration
algorithms)– New calibration constants– Tower swapping
• Procedure to do the reprocessing– Create a new version of task in the pipeline– Run the new task– GINO does not understand multiple versions of the “same”
data product (we’ll revisit this later)• May not need to redo everything

Make It So – Proof of ConceptMake It So – Proof of Concept
• Makefile that implements dependency flow from previous graph.
• Reproduces SVAC pipeline directory structure.
• Doesn’t actually do any work.
