3 Dec 2015 | | Abstract: | Current and future astroparticle physics experiments are operated or are
being built to observe highly energetic particles, high energy electromagnetic
radiation and gravitational waves originating from all kinds of cosmic sources.
The data volumes taken by the experiments are large and expected to grow
significantly during the coming years. This is a result of advanced research
possibilities and improved detector technology. To cope with the substantially
increasing data volumes of astroparticle physics projects it is important to
understand the future needs for computing resources in this field. Providing
these resources constitutes a larger fraction of the overall running costs of
future infrastructures.
This document presents the results of a survey made by APPEC with the help of
computing experts of major projects and future initiatives in astroparticle
physics, representatives of current Tier-1 and Tier-2 LHC computing centers, as
well as specifically astroparticle physics computing centers, e.g. the Albert
Einstein Institute for gravitational waves analysis in Hanover. In summary, the
overall CPU usage and short-term disk and long-term (tape) storage space
currently available for astroparticle physics projects’ computing services is
of the order of one third of the central computing available for LHC data at
the Tier-0 center at CERN. Till the end of the decade the requirements for
computing resources are estimated to increase by a factor of 10.
Furthermore, this document shall describe the diversity of astroparticle
physics data handling and serve as a basis to estimate a distribution of
computing and storage tasks among the major computing centers. (Abridged) | | Source: | arXiv, 1512.0988 | | Services: | Forum | Review | PDF | Favorites | |
