Documents, Tools & Visualisations

Documents

Document Description
WLCG Document repository WLCG documents, reporting etc.
HL-LHC Computing Upgrade R&D The data volumes anticipated in HL-LHC running will be significantly more than those currently managed, and will be at the multi-Exabyte scale. This implies significant increases in the scale of computing and data management facilities, as well as challenges in software.
How to run the HEP-SPEC06 benchmark

Tools

Information Systems

GOCDB GOCDB is the official repository for storing and presenting EGI topology and resources information.
OSG Site documentation for OSG sys-admins.
CRIC Information about WLCG physical computing resources (to replace REBUS in early 2020).
REBUS REBUS is the Resource, Balance and Usage website for the whole of WLCG, including topology information, resource pledges, and installed capacities.

Monitoring

SAM3 The Service Availability Monitoring (SAM) system is used to monitor the availability and reliability of resources within the production infrastructure.
Experiment Dashboards Monitoring data collected from the computing systems of the LHC experiments.

Grid Accounting

CRIC Information about WLCG physical computing resources including pledges and accounting.
EGI accounting portal A single entry point, used for WLCG Accounting on grid usage and including OSG.
GRACC OSG-only accounting.

Support

GGUS GGUS (Global Grid User Support) is the primary channel of requesting support when using the grid.

Network

LHCOPN - LHC Optical Private Network LHCOPN is the network for the T0-T1 data transfer.
LHCONE The objective of LHCONE is to provide a collection of access locations that are effectively entry points into a network that is private to the LHC T1/2/3 sites.
GEANT GÉANT is the pan-European data network dedicated to the research and education community.
ESnet ESnet connects together the US tier sites, as well as providing transatlantic connections to CERN and elsewhere in Europe and Asia.

Middleware

UMD

Unified Middleware Distribution (UMD) is a consistent and tested set of middleware products, available for use for grid computing on EGI/WLCG. More info here.

ARC The Advanced Resource Connector (ARC) middleware integrates computing resources and storage facilities.
Grid Community Forum The Grid Community Forum (GridCF) is a global community that provides support for core grid software, derived from the Globus Toolkit.
