Besides clustering and content based routing the technique
of host
virtualization is another possibility of enhancing the
availability of central
services. The talk will give a short introduction to pseudo
virtualization before
focusing on the open source XEN virtualization and the Sun
Solaris container
concept. Different aspects like base features, automatic
provisioning, file...

Carsten Germer
(DESY)
24/04/2007, 09:45
The computersystem for the central content management system
at DESY consists of
loadbalancers, webservers, application servers and database
servers.
The setup makes use of common software such as Apache, Zope etc.
This talk will give an overview over the setup and goes into
some details of the
Apache and loadbalancing setup.

DESY offers to the research and administration groups full
technical support for their web projects. The talk will
show, how the service is organized and give information on
the Web-Office project, which started 5 years ago.
Mr
Peter Grandi
(Diamond Light Source Ltd.)
24/04/2007, 11:45
Diamond Light Source is a light source synchrotron facility
of recent construction.
Computing and networking must support both production and
research. Mostly
production in the running of the synchrotron, mostly
research in the experimental
beamlines attached to it.
This has required a dual structure, and especially for the
beamline system a careful
attention to growth...
Mr
Gianluca Peco
(INFN Bologna)
24/04/2007, 12:15
Most of the services of the GRID infrastructure require
robust and
efficient database backends, providing high performances as
well as fault
tolerance mechanisms and fast disaster recovery procedures.
To this end, the Italian Tier-1, in collaboration with CERN
and the
other Tier-1s of the WLCG, has started a deployment and
production phase
of Oracle database services, that will be...

Several disk storage systems have been evaluated at the
RHIC/USATLAS Computing
Facility as part of an ongoing project to identify solutions
capable of accommodating
a large projected growth in storage demand over the next
five years. A preference is
given toward lower-cost, high-density, commodity solutions
using SATA and SAS drives.
This talk will survey the testing...

I'll discuss how to tune a GPFS filesystem and problems that
GPFS discovered in out
network and systems.
Dr
Vladimir Sapunenko
(INFN-CNAF)
25/04/2007, 12:15
Experiences of deployment, tuning and administration of
large GPFS cluster (700 nodes, 130TB of disk space) will be
presented.
Cary Whitney
(LBL/NERSC)
25/04/2007, 12:40
Using HPSS as a GPFS storage pool, thus allowing automatic
migration of data to and
from HPSS from a GPFS filesystem. This is work being
developed at NERSC and SDSC.
Mr
Peter Kelemen
(CERN)
25/04/2007, 16:00
We report on the progress of ongoing silent data corruptions
investigation
at CERN. In the last couple of months, CERN has been
systematically
collecting and analysing observations of data corruptions in
the CERN
computer centre. Current results and the toolset used in the
investigations will be presented.
Mr
Michel Jouvin
(LAL / IN2P3)
26/04/2007, 09:00
This talk will present GRIF experience of managing a
distributed site with
Quattor and show how Quattor has been a critical tool for
building a unique,
geographically distributed, technical team.
Mr
Axel Jäger
(Forschungszentrum Karlsruhe)

At GridKa the system monitoring tool Nagios is used to check
the status of servers,
worker nodes, storage systems, network components, services,
and infrastructure (e.g.
UPS and cooling).
We'll present a brief summary about the setup and the
hierarchical structure of the
Nagios system at GridKa.

Andrew Elwell
(University of Glasgow)
26/04/2007, 09:50
We will cover the use of Cfengine (http://www.cfengine.org)
to fully manage a grid
cluster, and maintain software and configuration of worker
nodes, grid and disk
servers. We will demonstrate the ease of extending the
cluster to new hosts, and
classes of hosts, together with the simplicity of
maintaining the grid software ie,
R-GMA bugfix
Mr
Owen Synge
(Desy)

This talk reports upon the Virtualization users workshop
held earlier this year at
DESY. HEP Use cases and applications of Virtualization on
the worker node became the
focus of the discussions. To provide some illustration
D-Caches usage of
Virtualization will be summarized.

System Management Working Group (SMWG) of sys admins from
Hepix and grid sites has been setup to address the fabric
management problems that HEP sites might have. The group is
open and its goal is not to
implement new tools but to share what is already in use at
sites according to existing best practices. Some sites are
already publicly sharing their tools and sensors and some
other...

I compared the performance of several HEP processor from
Intel and AMD when running
32bit and 64 bit code on SL4 using typical HEP code
I started also a look to Spec CPU 2006 int and fp on a 4core
intel processor
Manfred Alef
(Forschungszentrum Karlsruhe)
27/04/2007, 09:25
I'll continue the discussion about CPU benchmarking. New
topics are:
- experiences with new worker nodes at GridKa,
- quad core measurements,
- differing levels of optimization,
- first SPEC CPU2006 results.
Alf Wachsmann
(SLAC)

Parallel computing in HEP is regarded as exotic and
unnecessary (at best). I will
talk about the
recent BaBar D0 mixing results and how parallel computation
helped. I will also
illustrate that
parallel computing will be the only way to take advantage of
the upcoming "many-core"
CPUs.
Manfred Alef
(Forschungszentrum Karlsruhe)
27/04/2007, 11:35
This talk describes the way CPU benchmark measurements are
used in planning of CPU procurements and accounting settings
at GridKa.
