09:30Jack Schmidt (FNAL) Windows 2000 in the Fermilab Security Environment [ram] [pdf]
Fermilab is in the midst of their Windows 2000 rollout. The lab has a set of security restrictions approved by the DOE that have a direct affect on or domain design and implementation. I will higlight issues that have come up and how the Windows 2000 Migration team is working with the lab Computer Security team to follow the security policy set by the lab but still allow OU Administrators control over their environment- and meet the deadlines set by the lab and DOE!
10.00Dennis Wisinski Windows NT to 2000/XP Migration at SLAC [ram] [pdf]
SLAC is in the planning and design stage for a site-wide conversion to Windows 2000/XP, a project we hope to have completed by June 2003. On the infrastructure side, I cover early design decisions regarding DNS, Active Directory architecture, network topology, and test-lab construction. On the client side I discuss some of the more important issues considered in the selection of Windows XP as the target platform for user migration.

SLAC is currently evaluating hardware for Linux batch machines from 11 different vendors. I shall report about our testing procedures, criteria, and results.
09:30Andrei Maslennikov (CASPUR) CASPUR Storage Lab [ram] [pdf]
We have set up our Storage Laboratory to test and compare various storage-related solutions. Will be discussed: architecture, current program of tests and first results. Buzzwords: Fibre Channel, iSCSI, SCSI-over-LAN/WAN, GFS, GPFS, Sanergy, AFS, NFS, RFIO.
10.00Alan Silverman (CERN) Computer Centre Shutdown/Startup [ram] [pdf]
10.30Coffee Break
11.00Maurizio Davini (Physics Department PISA)Clustering with openMosix [ram] [pdf]
openMosix is a spin off the original Mosix project due to Moshe Bar. It's a software package that enhance Linux kernel ( x86 version) with cluster capabilities. openMosix allows for the automatic and transparent migration of processes to other nodes in the cluster.
11.30Wofgang Friebel (CERN) An AFS administration framework [ram] [pdf] [html]
A framework will be described that was developed at CERN to simplify the AFS administration. It consists of several perl modules that provide a homogeneous interface to AFS functions and to the management of AFS space (grouping of volumes, delegation of administration privileges).
Based on that framework a tool was written to manage the AFS space for working groups and experiments. Other existing tools are being converted to use the new interface.
12.00Alan Lovell (CERN) CERN CVS Service [ram] [pdf]
After realising that a number of groups had to set up and maintain their own CVS servers, a project has been set up to address this question globally. Requirements have been collected and possible implementations are being evaluated to address these requirements within the resource constraints of the division.
12.30Sandy Philpott (JLAB) Cfengine [ram] [pdf] [html]
14.00Alan Lovell (CERN) CERN PRINT Service Status Update [ram] [pdf]
The PRINT service offers network printer spooling to the whole CERN site. The clients use a DNS table to address the server that corresponds to the printer in a transparent way, this allows to distribute the spooling for load balancing and disaster recovery. The system is currently running in three old PCs. A hardware upgrade is coming soon. A system software upgrade is required for security reasons. This has implications on Appletalk protocol support. Spooler software and filter upgrades are also in the pipeline.
14.20Lisa Giacchetti (FNAL) Who let the Dog(s) in!? [ram] [pdf]
14.50Alan Lovell (CERN) ASISwsmp (ASIS with RPM backend) [ram] [pdf]
There is currently a joint effort of PC and ADC group to provide a versionof the ASIS Workstation Manager (ASISwsm) that manages the ASIS client configuration using RPMs for the ASIS products concerned rather then checking all the files in the ASIS file tree. This move improves greatly performance of the ASIS client.
15.10Roberto Barbera (INFN) Grid activities at ALICE [ram] [pdf]
ALICE is one of the four approved experiments which will run at the Large Hadron Collider (LHC), on the way to be built at CERN. The main goal of ALICE is the study of the so called Quark Gluon Plasma (QGP) expected to be formed when, in ult...
15.40Coffee Break
16.00Alan Lovell (CERN) Solaris 8 certification status at CERN [ram] [pdf]
Until now only unofficial support for Solaris 8 (HW0401) has been provided at CERN. Work is under way to provide full support to Solaris 8 (HW0202) and at the same time upgrade the Solaris installation server hardware. Solaris 8 is the first Solaris version to feature DHCP/BOOTP support for network installations which changes considerably the installation procedure that was previously relying on the RARP protocol. A new version of the Sun development environment (Forte Developer 7) has been provided on request of CMS. It has been tested to successfully solve C++ template compatibility problems present in previous versions.
16.30Tanya Levshina (FNAL) NGOP Status Report [ram] [pdf]
Fermilab Distributed Management System (NGOP) has been deployed since January, 2000. It is monitoring about 600 nodes. New features implemented since the last HEPIX as well as future steps to improve NGOP will be presented.
17.00Helge Meinhard (CERN) Computer Centre Supervision at CERN with PVSS [ram] [pdf]
17.30Cary Whitney Linux Storage Solutions
PDSF has been fortunate to have the opportunity to beta and evaluate two types of NFS storage for our cluster. I would like to present our findings; the performance of these units and compare them to more traditional options. I have been release from NDA's to give the presentation, but the slide will be made public in the May/June time frame.
Friday Apr 19
9.00Alan Silverman (CERN) Large System SIG report [pdf]
09.30John Gordon (RAL) The UK Grid for Particle Physics [pdf]
RAL will host a Tier1 Centre for all LHC experiments but the centre will need to do more than that. It will also be a TierA Centre for the BaBar Grid as well as participating in the DataTAG, InterGrid, and the grid work of CDF and D0. The computing workload of existing experiments will also need to be supported. I will describe how RAL and other UKI sites plan to meet these diverse challenges.
10.00Luca Dell'Agnello (INFN CNAF) A prototype for INFN Tier 1 Regional Center [pdf]
We discuss briefly the present status and future plans for the prototype of Italian Tier1 Regional Center, a computing facility for HEP community (LHC experiments, CDF, VIRGO). Our aim, in the next years, is to study potential issues arising in a large-scale production environment (the RC is already used by some experiments) and to develop, or adopt, suitable solutions. Our activity has presently strong interactions with DataGRID, DataTAG, INFN-GRID, GLUE and LHC experiments Data Challenges.
10.30Coffee Break
11.00Giuseppe Sava (INFN Catania) INFN-GRID testbed monitoring system [pdf]
Inside the INFN-GRID testbed, a distributed monitoring system is used to control the network and computing resources in order to evaluate several critical factors such as the reachability of hosts and the availability of services. The system also enables the activation of automatic faults notification via e-mail. In this talk we describe the architecture and the features offered by the opensource package Netsaint the monitoring system is based on, as well as the implementation of several add-ons oriented to the control of some real- life problems. The use of a simple web portal with clickable geographical map for GRID collaboration in Italy is shown. The use of Netsaint in the testbed of Alice experiment, involving a large number of geographic-scale distributed computing resources is also shown. A very short demo will be provided.
11.30David Kelsey (RAL) Grid Security - status and issues [pdf]
I describe the current status of Grid security, i.e. Authentication and Authorisation, in the EU DataGrid project and some of the HEP Grid projects in the USA. Current plans to improve Authorisation are presented. There are many issues and problems to be solved before this will scale to a full LHC-scale Grid. What impact will all this have on HEP Computer Centres?
12.00Jan Iven (CERN) Fabric Management [pdf] [html]
12.30John Gordon (RAL) LCG YAG? The LHC Computing Grid - yet another grid? [pdf]
The LHC Computing Grid is a next generation grid deployment project. It intends to use the developments of current Grid projects (EDG, iVDGL, PPDG, CrossGrid, and the various national grids) to build a prototype production grid for the computing needs of the LHC. I will describe the project and how it could interface with HEPiX.
