Prerequisites
To submit jobs via Nordugrid ARC middleware, you need:
- Grid user certificate
This is best obtained from CERN: CERN CA. Being registered with CERN HR and having a CERN computer account are the pre-requisites. Users with FNAL accounts can obtain a certificate from the relevant FERMILAB CA. From those not eligible to either solution above, there is the possibility of requesting a certificate via the Swiss CA
In order to carry on the following steps, your user certificate and private key must be installed in the .globus subdirectory of your home directory on the client machine. You can find instructions on how to do that in here. While this focuses on ATLAS, the steps to extract and install the certificate are the independent from the specific experiment.
- ARC client
Users operating from the UIs (recommended) can setup the client from CVMFS:
# export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
# source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh
# lsetup emi
Otherwise installing a local client on any linux machine is possible by following the instructions for your specific operating system: Install ARC client
- Have the certificate registered with a Virtual Organisation (VO), e.g. for ATLAS, browse to the [https://lcg-voms2.cern.ch:8443/voms/atlas/user/home.action ATLAS VOMS service). The prerequisite for this step is having installed your personal certificate in your browser
arcinfo
First, verify that the user interface is installed and you can see the submission endpoints
