Hardware status in Ferrara





EDG 1.4.11 is installed on RH6.2 and RH7.3 nodes
PBS queue specific for RedHat 7.3 nodes is defined
BaBar VO is authorized to access the INFN RBs in Bologna
(cnaf009g.cnaf.infn.it)
Resources in Ferrara are visible from the IC RB as well (thanks to
David Colling!)
RH7.3 resources are accessible by using in your JDL:
Requirements=isMember(other.RunTimeEnvironment,"FERRARA")
&& other.QueueName == "wn73";

An SP5 federation is installed and available:
babarbecue.fe.infn.it::/babar/databases/SP5/BKG/bbrprod/9195/BaBar.BOOT

Contains conditions + Dec2001 background collection

Integration into EDG





Pack software in relocable rmps
Give a tag to software, will be published as RunTimeEnvironment
and used in JDL files.
Send RPMs and tag to the EDG Integration Team, that will test
the rpms on a micro-testbed. If everything OK, they will include
them in a new EDG software release.
Each sitemanager will be notified of the new release, and will
upgrade his testbed farm.
Accessory parts to install software via LCFGng are also needed,
and are ready since some time (we showed them in Karlsruhe)

Building an rpm for Moose

An RPM to run Moose has been built and installed “by hand” on
RH7.3 worker nodes:
[root@grid7]# ls /opt/babar/
12.4.0-Roo tcl8.0

Contents:
[root@grid7]# ls /opt/babar/12.4.0-Roo/
bin etc library shlib src
bin: MooseApp (77MB)
etc: site.sh (setup envvar like BFROOT, OO_FD_BOOT, LD_LIBRARY_PATH)
library: a link to init.tcl (tcl error otherwise…)
shlib: shared libraries (37MB)
src: tcl files and flat files (16MB)
Total RPM:
136MB

Determining required parts






Naively, MooseApp + tcl file obtained with dump mechanism
For a number of reasons, we could not obtain the latter
Shared libraries are also needed
Anything else?
Use strace/ldd
The answer is:
475 tcl files
 165 flat files
 42 shared libraries


Running Moose


Moose was successfully run on RH7.3 worker nodes by using
both the INFN-CNAF and IC Resource Brokers
JDL script:
[bozzi@grid1 ~/testSPGrid]$ more Moose.jdl
Executable = "Moose.csh";
StdOutput = "Moose.out";
StdError = "Moose.err";
InputSandbox = {"Moose.csh", "MooseProductionOptions.tcl",
"B0B0bar_generic.dec"};
OutputSandbox = {"Moose.out", "Moose.err"};
Requirements = IsMember(other.RunTimeEnvironment,"FERRARA") &&
other.QueueName == "wn73";

Assuming Options, .dec and .csh files are built by someone else

Next steps



Include RPM in EDG release (2.0 by end of the month?)
Upgrade from 12.4.0-Roo to 13.4.0-roo-X
This allows us to use virtually any CPU with EDG software
installed.




Bottleneck: access conditions
Solution: at least a conditions DB per country/region/Babar site
Extend metodology to sites already running Babar software
(Wahid Bhimji, Tim Barrass), or to sites using Globus+VDT
(Dirk Hufnagel)
Start working on bookkeeping and production tools (Douglas
Smith, Marc Kelly, Daniele Andreotti), integration with Grid
portals like Genius (Daniele, Concezio)

Test rpm (2/3)
Made some changes to the EDG standard config files on the
LCFGng server :
• Added the WP8/BaBar/ repository
• Created the BaBar-rpm.h containing the rpm-list for BaBar
software.
ls /opt/local/linux/6.2/RPMS/WP8/BaBar/
Makefile Moose-0.1-1.i386.rpm
more /opt/local/linux/6.2/rpmcfg/BaBar-rpm.h
/* BaBar SOFTWARE RPM LIST */
Moose-0.1-1

Test rpm (3/3)
Added the following lines to WN-rpm and CE-rpm of LCFGng
server config files, in order to install this rpm on the Computing
Element and Worker Node:
/* BaBar software */
#include "BaBar-rpm.h"
Added to redhat62-cfg.h a BaBar line to set the related repository
for automatic updating.
