The computing model of the ATLAS experiment was designed around the concept of grid computing and, since the start of data taking, this model has proven very successful. However, new cloud computing technologies bring attractive features to improve the operations and elasticity of scientific distributed computing. ATLAS sees grid and cloud computing as complementary technologies that will...

The Datacenter at the Galician Institute of High Energy Physics(IGFAE) of the Santiago de Compostela University (USC) is a computing cluster with about 150 nodes and 1250 cores that hosts the LHCb Tiers 2 and 3. In this small datacenter, and of course in similar or bigger ones, it is very important to keep optimal conditions of temperature, humidity and pressure. Therefore, it is a necessity...

For over a decade CERN's fabric management system has been based on home-grown solutions. Those solutions are not dynamic enough for CERN to face its new challenges such as significantly scaling out, multi-site management and the Cloud Computing model, without any additional staff. This presentation will illustrate the motivations for CERN to move to a new tool-set in the context of the Agile...

CMS is using a tiered setup of dedicated computing resources provided by sites distributed over the world and organized in WLCG. These sites pledge resources to CMS and are preparing them specially for CMS to run the experiment's applications. But there are more resources available opportunistically both on the GRID and in local university and research clusters which can be used for CMS...

Solid state drives (SSDs) provide significant improvements in random I/O performance over traditional rotating SATA and SAS drives. While the cost of SSDs has been steadily declining over the past few years, high density SSDs continue to remain prohibitively expensive when compared to traditional drives. Currently, 1TB SSDs generally cost more than USD $1,000, while 1TB SATA drives typically...

The WLCG infrastructure moved from a very rigid network topology, based on the MONARC model, to a more relaxed system, where data movement between regions or countries does not necessarily need to involve T1 centers. While this evolution brought obvious advantages, especially in terms of flexibility for the LHC experimentโs data management systems, it also opened the question of how to monitor...
