All users on your system can use LSF. As long as they have loaded LSF in their profile. I usually run these commands so that everybody loads LSF on logon:
- cd /etc/profile.d
- ln -s $LSF_CONFDIR/profile.lsf lsf.sh
- ln -s $LSF_CONFDIR/cshrc.lsf lsf.csh
This loads LSF paths and binaries in your profile, i.e you can run lsid, bsub, bjobs, etc without having to specify the path.
I have never personally used busers but that command is related to lsb.users. In that file you define users and groups that you want to use inside lsb.queues for your queue definitions, e.g. you want a certain queue to be available only for a certain group.
