Group Leader:
Markus Schulz
The GT (Grid Technology) group is responsible for
maintaining and evolving CERN’s grid software components and grid
monitoring infrastructure.
The group participates in
EMI activities
on Data Services, Infrastructure Services and Quality Assurance. We
also monitor and drive the deployment of middleware relevant for
WLCG.
GT coordinates
work
related to middleware development, release preparation and
operations.
The group consists of four
sections:
Data Management Software
GT-DMS |
The section develops, integrates,
tests and supports CERN's grid data
management middleware.
The File Transfer Service (FTS) is
used to distribute the LHC data
between participating sites for
storage and analysis.
The Disk Pool Manager (DPM) is a
simple and most commonly used
solution for implementing and
managing storage on the grid, and
the LCG File Catalogue (LFC) allows
the files involved to be tracked at
the grid level.
These components are installed and
used throughout the WLCG/EGI
infrastructure.
The section is also home to CERN's
contribution to D4Science, a
production e-infrastructure
supporting several virtual
organisations.

Software Lifecycle
GT-SL |
The SL Section provides services and
support for Testing, Certification
and Release- Management for the
grid middleware developed by the
gLite product teams.
It manages the preparation of the
releases (EMT) and of the software
validation and packaging. The
Section also runs the build, test
and certification infrastructure
based on ETICS and vNode services.

Tools for Operations,
Monitoring
GT-TOM |
The Tools for Operations and
Monitoring (TOM) section is
responsible for designing,
developing and running tools used by
WLCG for the daily operation of its
production infrastructure.
The provided tools are grouped in
four functional areas:
-
Service Monitoring (Nagios,
SAM, SWAT, Gridview
Availability
reporting)
-
Production Messaging
systems (ActiveMQ)
-
Grid Information
Systems (BDII, Gstat,
GLUE)
-
WLCG Operational
portals (Gridmap,
WLCG MoU reporting,
WLCG installed
capacity)
The TOM Section also provides tools
and services to EU projects such as
EGI.eu.
