High Energy Physics

UU

Uppsala University, Department of Physics and Astronomy (UU)

Uppsala University was the first to be founded in Scandinavia in 1477. Several well-known scientists like von Linné, Celsius, Scheele, Ångström and Siegbahn have been affiliated to the University. The University has about 35 000 students who represent a visible community in the rather small (100 000 inhabitants) and old city of Uppsala. The Grid Computing activities at Uppsala University dates back to the creation of the NorduGrid project in 2001. This project was initiated by high energy physicists in the Nordic Countries who wanted to create a computin

Dynamic federations: storage aggregation using open tools and protocols

Dynamic federations: the Uniform Generic Redirector (UGR) (Dynamic federations: storage aggregation using open tools and protocols)

The Unifor Generic Redirector (UGR) is the core of the Storage federation system that we designed and built to match with the existing and upcoming Grid-related data management architectures. The system is able to federate storage sites and metadata endpoints that expose a suitable data access protocol, into a transparent, high performance storage federation that exposes a unique name space. The architecture can accommodate LFN/PFN algorithmic name translations without the need of catalogues. On the other hand,

SAM

Service Availability Monitoring (SAM)

SAM is a grid monitoring and reporting system for large-scale production grids.

It builds on top of open-source components such as 

StoRM

Storage Resource Manager (StoRM)

StoRM is a

  •     light
  •     scalable
  •     flexible
  •     high-performance
  •     file system independent
storage manager service (SRM) for generic disk based storage system, compliant with the standard SRM interface version 2.2. StoRM provides data management capabilities in a Grid environment to share, access and transfer data among heterogeneous and geographically distributed data centres.In particular, StoRM works on each

Fermilab

Fermi National Accelerator Laboratory (Fermilab)

Scientists at Fermilab carry out research in high-energy physics to answer the questions: What is the universe made of? How does it work? Where did it come from?

NeIC

Nordic e-Infrastructure Collaboration (NeIC)

NeIC (Nordic e-Infrastructure Collaboration) is a collaboration between the Nordic countries to facilitate the development of e-Infrastructure solutions for Nordic research.   One of the projects NeIC runs is NDGF - the distributed Nordic WLCG Tier-1.   More science areas will follow.

LFC

LCG File Catalog (LFC)

The LCG File catalogue (LFC) offers a hierarchical view of files to users, with a UNIX-like client interface. The LFC catalogue provides:

  • Logical File Name (LFN) to Storage URL (SURL) mappings (via a GUID);
  • Authorisation on its logical

DPM

Disk Pool Manager (DPM)

The Disk Pool Manager (DPM) is a lightweight storage solution for grid sites. It offers a simple way to create a disk-based grid storage element and supports both standard (HTTP/S, NFS 4.1/pNFS) and grid specific protocols (SRM, gridFTP, XROOTD, RFIO) for file management and access.

GFAL 2.0

GFAL 2.0

GFAL2 is a framework for Grid and Cloud file access, file transfer and file management.

The GFAL 2.0 library : The GFAL 2.0 library (gfal2-core) provides a unified and protocol-generic API for file access, file transfer and file management operations in Grid and Cloud environments. GFAL 2.0 allows to build applications using the Grid technologies ( file, GridFTP, RFIO, Dcap, SRM, LFC, Http/Dav, xrootd ) in a transparent manner.

The GFAL 2.0 transfer library: The GFAL 2.0 transfer library (gfal2-transfer) is an addit

Grid Information System

Grid Information System

The Grid Information System provides detailed information about grid services. The Grid Information System system has a hierarchical structure of three levels. The fundamental building block used in this hierarchy is the Berkley Database Information Index (BDII). Although the BDII has additional complexity, it can be visualized as an LDAP
