Tier 2 center GoeGrid, Current Status and Future Plans — •Erekle Magradze, Haykuhi Musheghyan, and Arnulf Quadt — II. Physikalisches Institut, Georg-August Universität Göttingen, Deutschland

GoeGrid is the world-wide LHC computing grid (WLCG) Tier 2 center in Göttingen and is a part of the ATLAS Distributed Computing (ADC) infrastructure. The center is actively involved in ATLAS Distributed production and analysis processes since 2008. It provides computational power of 305 computing nodes with more than 2700 cores, storage space from 25 servers with capacity of 1.1PB in total and local network of 10Gb/s. The stable performance of the GoeGrid that is reflected in the reliability and availability reports is achieved through the efficient administration and in time problem detection which is done using the meta-monitoring framework HappyFace. From the experience gained during the operation of the Tier 2 center, there is a collection of scripts for solution of simple problems. This fact served as a motivation to build the problem evaluation, detection and action taking system, which will be based on a Fuzzy Neural Network approach and will use the monitoring data from the HappyFace framework. This system should help the site administrator to automate all routine and time consuming work and also to get suggestions and hints for possible solutions of the problem; even more, solve simple problems based on accumulated knowledge automatically.
