Abstract

A considerable amount of computing power is needed for Gaia data processing during the mission. A pan European system of six data centres are working together to perform different parts of the processing and combine the results. Data processing estimates suggest around 1020 FLOP total processing is required. Data will be transferred daily around Europe and with a final raw data volume approaching 100 TB. With these needs in mind the centres are already gearing up for Gaia. We present the status and plans of the Gaia Data Processing Centres.
