The EGI / WLCG grid infrastructure can be accessed from any Nikhef-managed machine running a variant of Red Hat Enterprise Linux 6 or higher (e.g. CentOS 6 or 7) or from the Grid UI (i.e., bosui.nikhef.nl).
To access the Grid from a Nikhef-managed machine, you need to use the grid middleware tools:
source /cvmfs/grid.cern.ch/etc/profile.d/setup-cvmfs-ui.sh ## bash/ksh/zsh
first. Csh users will have to first run
/bin/bash
or perhaps even better, change their login shell to bash or zsh. (If you are accessing the Grid from a UI, you can skip this step.)
Sourcing the setup script will set up all required environment variables for running the middleware commands.
Once you have sourced the grid middleware tools or have logged into the UI, type
voms-proxy-init --voms <YOUR-VO>
to create a voms proxy. Sample output:
$ voms-proxy-init -voms pvier Enter GRID pass phrase: Your identity: /O=dutchgrid/O=users/O=nikhef/CN=Some User Creating temporary proxy .......................................... Done Contacting voms.grid.sara.nl:30000 [/O=dutchgrid/O=hosts/OU=sara.nl/CN=voms.grid.sara.nl] "pvier" Done Creating proxy ................................................................... Done Your proxy is valid until Fri Dec 7 00:08:49 2007
Congratulations! You are now ready to use grid middleware tools.

lcg-infosites --vo pvier -f NIKHEF-ELPROD all
Commands to start running your job can look something like:
# Delegate your proxy to an endpoint (-e) with a string to identify your proxy delegation glite-ce-delegate-proxy -e [CREAM-CE_SERVER]l:8443 [STRING] # Submit your job to a resource (-r) queue with the output (-o) going to a directory (jids) # using the delegation ID string in the previous command and finally adding the job descritpion file (JDL) for your job. glite-ce-job-submit -r [CREAM-CE_SERVER]:8443/cream-pbs-[QUEUE] -o jids -D [STRING] [JDL-FILE.JDL] # Check the status of your job... glite-ce-job-status https://[CREAM-CE_SERVER]:8443/[JOBID]
