Our site name with the GOC is WISC-OSG-EDU (VORS)

VOs supported & grid-mapfile

Each VO is mapped to a username. Important: These usernames must have their home directories on the shared filesystem (in /nfs)

If you want to run jobs on this machine for testing, you will need to add yourself to the grid-mapfile. The file to edit is at /opt/osg-1.2/edg/etc/grid-mapfile-local. Add an entry like the following:

"/DC=org/DC=doegrids/OU=People/CN=Scott Kronenfeld 301773" osgedu 

The first part is your certificate info. The second part is the UNIX user to run as. You must either map to the osgedu user or the mis user (you cannot map to your own user because your home directory is not shared on NFS). Then run $VDT_LOCATION/edg/sbin/make-gridmap to force an update to the grid-mapfile.

Every few months, a new VO package will be released. Follow the instructions from the GOC for the update, and afterwards, fix the edg-mkgridmap.conf file. There are two steps:


NFS is used to distribute the CA certificates and worker node software. Root squash is enabled, so on the headnode everything needs to be done in the /osg_nfs directory. View the /nfs directory to see how things look on the worker nodes.

All users who run jobs will need to have their home directories on NFS.


The RSV user is 'rsv'. A service certificate is used for the RSV service.
