3. Workload Management System (WMS)
The Workload Management System (WMS) is the gLite service that allows users to submit jobs, and performs all tasks required to execute them, without exposing the user to the complexity of the Grid.
The workload manager (WM) is the principal component in the WMS.
Purpose of the Workload Manager (WM) is to accept and satisfy requests for job management coming from its clients
The WM hands over the job to an appropriate Computing Element (CE) for execution taking into account requirements and the preferences expressed in the job description.

4. Logging and Bookkeeping service (LB)
The Logging and Bookkeeping service (LB) tracks jobs in terms of event (important points of job life, e.g. submission, finding a matching CE, starting execution etc.) gathered from various WMS components as well as CEs.

gLite WMS Architecture
Acts as the portal for accepting all external requests to the workload manager.
Job submission,
cancellation expressed
via a JDL

7. immediately available
gLite WMS Architecture
Keeps submission
requests
Requests are kept
for a while
if no resources are
immediately available

Valparaíso, Chile. Joint GISELA/EPIKH School for Grid Site Admins. Nov 22, 2010 7

8. gLite WMS Architecture
Finds an appropriate
CE for each submission
request, taking into account
job requests and preferences,
Grid status, utilization policies
on resources

Valparaíso, Chile. Joint GISELA/EPIKH School for Grid Site Admins. Nov 22, 2010 8

9. gLite WMS Architecture
A cache where overall resource information
about the grid is stored for querying by the matchmaker.
Updating these info via the information updater.
A. J Rubio-Montero
Valparaíso, Chile. Joint GISELA/EPIKH School for Grid Site Admins. Nov 22, 2010 9

10. gLite WMS Architecture
Updating of information
is carried out by reading information from the top-level BDII server
of the virtual organization.

11. gLite WMS Architecture
The LB is responsible to:
- Stores events generated by the various components of the WMS
- Querying the LB user can retrieve information about the status of the job

12. Preliminaries
The instructions provided in this presentation assume that you are going to use a machine with Scientific Linux CERN 4.8 (32 bits) installed.
Virtual Machine image (GILDA VM Base_SLC4.8_i386) available at:
GILDA VO: ATTENTION PLEASE: DON’T MAKE THE FOLLOWING INSTRUCTIONS FOR GILDA VO IN YOUR SITE IF YOU DON’T SUPPORT THIS TUTORIAL VO. IT’S JUST FOR TEST INSTALLATIONS AND USER TEST
GISELA: This project maintains prod.vo.eu-eela.eu from EELA-2 as the production VO for its infrastructure.
A. J Rubio-Montero
Valparaíso, Chile. Joint GISELA/EPIKH School for Grid Site Admins. Nov 22, 2010 12

13. To login to the VM you can use putty or winscp to open a terminal
Machine: clusterXX
Password: valparaisoXX / “passwordXX”

Valparaíso, Chile. Joint GISELA/EPIKH School for Grid Site Admins. Nov 22, 2010 13

14. Network Time Protocol Let’s check if date’s machine is correct with:
if NTP date isn’t correct:
/etc/init.d/ntpd stop
ntpdate ntp-1.infn.it
/etc/init.d/ntpd start
/etc/init.d/ntpd status
ntpq -p
if not let’s configure file and make service start on boot:
chkconfig ntpd on

15. System requirements Please check: If you have a valid hostname
To verify, type:
hostname -f
To edit the hostname:
vi /etc/hosts
vi /etc/hostname
vi /etc/sysconfig/network
hostname <pc_name>

16. export REPOS=“dag ig-sl4 lcg-ca glite-bdii glite-wms glite-lb“
Repository settings
Specify the mrepo host:
export MREPO=
Configure the repository as follows
export REPOS=“dag ig-sl4 lcg-ca glite-bdii glite-wms glite-lb“
(“jpackage” is not necessary)
(“glite-generic” could induce dependency problems)
Get repositories with:
for name in $REPOS; do wget $MREPO/$name.repo -O /etc/yum.repos.d/$name.repo; done
Copy the gilda utils (Note: only for Gilda VO):
wget -O /etc/yum.repos.d/gilda.repo
Copy the UTFSM SL4 repository (only for this tutorial) wget /etc/yum.repos.d/utfsm-sl4.repo

17. YUM install Then update your host: yum clean all
Install CAs on ALL profiles:
yum install lcg-CA
GISELA:
cd /etc/yum.repos.d
wget
yum install eela-vomscerts
Gilda utils:(ATTENTION PLEASE: DON’T MAKE THE FOLLOWING FOR YOUR SITE IT’S JUST FOR THE TEST INSTALLATION!)
yum install gilda_utils
(Installs ca_Gilda and glida-vomscert)
Ig yaim:
yum install ig-yaim

18. WMS+LB+BDII installation
yum install ig_WMS ig_LB ig_BDII
Problem (only in SL4.8 no CERN): RPM incompatiblity between openlap and openldap-servers / openldap-clients
yum remove openldap
Problem: RPM incompatibility between “glite-security-voms-api-cpp” and “glite-security-voms-api-noglobus”
Yum error example:
Transaction Check Error
Transaction Check Error: file /opt/glite/lib/libvomsapi_nog.a conflicts between attempted installs of glite-security-voms-api-cpp slc4 and glite-security-voms-api-noglobus slc4

19. Force to install separately WMS and LB
Install WMS:
yum install ig_WMS
Install LB:
You can not install ig_LB in a straighforward way
yum install ig_LB
====================================================
Package Arch Version Repository
Installing:
ig_LB i _ig52_sl4 ig_sl4
Installing for dependencies:
glite-LB i glite-LB_sl4_updates
glite-security-voms-api-noglobus i slc4 glite-WMS_sl4_release
Try to select/install only a packet each time:
wget
rpm -ihv --nodeps glite-LB i386.rpm
wget
rpm -ihv --nodeps ig_LB _ig52_sl4.i386.rpm

20. Host cetificates Move the host cert to the right path
wget /etc/grid-security/clusterXX.tar.gz
cd /etc/grid-security
tar -xvzf clusterXX.tar.gz
Give them the right permissions
chmod 400 /etc/grid-security/hostkey.pem
chmod 644 /etc/grid-security/hostcert.pem
clusterXX ~]# ll /etc/grid-security/

24. Please test some security files
Test DN of host certificate only contain hostname (no service description):
openssl x509 -noout -in hostcert.pem -subject
subject= /C=IT/O=GILDA/OU=Host/L=VALPARAISO/CN=clusterXX.fis.utfsm.cl
CN must not contain:
host/clusterXX.fis.utfsm
<some kind of service>/clusterXX.fis.utfsm
Test the VO security configuration in /etc/grid-mapfile
For gilda VO:
cat /etc/grid-security/vomsdir/gilda/voms.ct.infn.it.lsc
/C=IT/O=INFN/OU=Host/L=Catania/CN=voms.ct.infn.it
/C=IT/O=INFN/CN=INFN CA

25. Testing WMS-LB From a UI enter:
~]$ voms-proxy-init –voms gilda
~]$ export GLITE_WMS_WMPROXY_ENDPOINT=
Create a .jdl file:
~]$ cat hostname.jdl
Type = "Job";
JobType = "Normal";
Executable = "/bin/hostname";
StdOutput = "hostname.out";
StdError = "hostname.err";
OutputSandbox = {"hostname.err","hostname.out"};

33. Top BDII Configuration
Attention: (gLite 3.1) BDII service always shows resource information at the same port than site-level or top-level information (2170)
Top BDII Configuration
BDII_HOST=clusterXX.fis.utfsm.cl
BDII_HTTP_URL=" <-posible bug?!!!
NTP_HOSTS_IP=" ntp-1.infn.it"
(Note: this modifies /etc/ntp.conf)
Then configure BDII (+WMS+LB):
/opt/glite/yaim/bin/ig_yaim -c -s /opt/glite/yaim/examples/siteinfo/mysite-info.def –n ig_WMS –n ig_LB -n ig_BDII_top
(To only install BDII: /opt/glite/yaim/bin/ig_yaim -c -s /opt/glite/yaim/examples/siteinfo/mysite-info.def -n ig_BDII_top)
A. J Rubio-Montero
Valparaíso, Chile. Joint GISELA/EPIKH School for Grid Site Admins. Nov 22, 2010 33

34. Top BDII Post Configuration
Set the CA autoupdate on
/opt/glite/yaim/etc/gilda/set_CAs_autoupdate.sh
Then Edit:
vi /opt/bdii/etc/bdii.conf
BDII_AUTO_UPDATE=yes
BDII_MODIFY_DN=yes
BDII_UPDATE_URL=
Restart BDII
/etc/init.d/bdii restart
Test bdii
ldapsearch -x -h localhost -p b mds-vo-name=local,o=grid
(Note:”ldapsearch -x -h localhost -p b mds-vo-name=resource,o=grid” for the resource information of this server)

35. Customize your Top BDII
In order to customize an own Site BDII list:
Install a HTTP server:
yum install -y httpd
Publish your customized glite-bdii-update.conf file (i.e. /var/www/html/bdii) as (
Set the BDII_UPDATE_URL accordingly in the file /opt/bdii/etc/bdii.conf file
Restart the BDII service
/etc/init.d/bdii restart
