Service Level Status

Nowadays, IT departments provide, and people use, computing services of an increasingly heterogeneous nature. There is thus a growing need for a status display that groups these different services and reports status and availability in a uniform way. The Service Level Status (SLS) system addresses these needs by providing a web-based display that dynamically shows availability, basic information and statistics about various IT services, as well as the dependencies between them

A Roadmap for HEP Software and Computing R&D for the 2020s

Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.Peer reviewe

Service level status: a new real-time status display for IT services

Configuration of Windows 2000 Operational Consoles and Accounts for the CERN Accelerator Control Rooms

The Windows 2000 configuration project was launched to set up the operational consoles, accounts, deployment procedures and packages of accelerator controls software on the new Windows 2000 operational consoles in the SPS Accelerator Control Room, the SPS surface buildings and the SPS experimental zones, in an automatic and reproducible manner. The configuration of the operational console environment is achieved by a combination of Windows profile settings for the Operations user account and group policy settings applied to security groups. A major restriction for all operational consoles (being located either in the CERN Accelerator Control Rooms or in one of the SPS surface buildings), is the fact that only a small set of users are allowed to perform actions in a restricted domain, in order to ensure secure access to the Accelerator Controls application software

CluMan - Cluster management toolsuit

LHC computing requirements are such that the number of CPU and storage nodes, and the complexity of the services to be managed are bringing new challenges. Operations like checking configuration consistency, executing actions on nodes, moving them between clusters etc. are very frequent. These scaling challenges are the basis for CluMan, a new cluster management tool being designed and developed at CERN. High-density displays such as heat maps, grids or color maps are more and more commonly used in various applications like data visualization or monitoring systems. They allow humans to see, interpret and understand complex and detailed information at a glance. We propose to present the ideas behind the CluMan project, and to show how high density displays are used to help service managers to understand, manage and control the state and behavior of their clusters
