Planck is an ESA satellite aimed at providing a full sky mapping of the cosmological anisotropies of temperature (T), and polarisation (P). It has been launch on May 14th 2009. The mission released its first cosmological results in spring 2013, extracted from the temperature data acquired between 12 August 2009 and 27 November 2010, which corresponds to 2 complete surveys of the sky. The second release followed on January 2015 and included 3 additionnal surveys for the temperature and also filtered polarization data. Unfiltered polarization data should be released by the end of 2015.
All Planck products can be retrieved from the Planck Legacy Archive website [1] and are described in detail in the Planck Explanatory Supplement [2]
The present document describes the L3 SMICA pipeline, one of the 4 pipelines which has produced the Planck foreground-cleaned CMB maps. It uses the Planck component separation framework which consists in a common repository for input data (frequency maps, source catalogs, beam transfert functions, etc) located on the Magique3 cluster at IAP.
Except for this data access, the pipeline itself is not tied to any Planck infrastructure. It uses the pipelet free framework to manage task chaining, traceability and task distribution on parallel clusters.
As a long term support of this pipeline, our plan is to use any cloud/virtual infrastructure available to run it when necessary. The cloud facilities would be used to pack the data together with a frozen version the code and its dependencies.
