RO-03-UPB este un nod Tier-2 din cadrul federatiei romane WLCG. Pe langa suportul pentru WLCG, RO-03-UPB face parte din structura grid al Europei de Sud-Est: SEEGRID-SCI cat si din structura nationala GridMOSI. Vom prezenta in cele ce urmeaza, serviciile RO-03-UPB in relatia cu arhitectura middleware-ului gLite.

First of all, let's start with a simple job. Let's run sleep 1. Here's the JDL.
Second thing, let's load the environment (see module implementation also).
[heri@fep-53-2 ~]$ . /opt/gLite/gLite-UI-3.2.4-0-Prod/etc/profile.d/grid-env.sh
[heri@fep-53-2 ~]$ voms-proxy-init --voms seegrid
Cannot find file or dir: /export/home/heri/.glite/vomses
Enter GRID pass phrase:

Let's find our CREAM-CE directly
[heri@fep-53-2 ssam]$ lcg-infosites --vo seegrid ce | grep gw02
8 0 1 0 1 gw02.seegrid.grid.pub.ro:8443/cream-pbs-seegrid
And run it:
[heri@fep-53-2 ssam]$ glite-ce-job-submit -a -r gw02.seegrid.grid.pub.ro:8443/cream-pbs-seegrid test.jdl
