Before using your cluster
After installing LSF and setting up your server hosts:
Log on to the LSF master host as root.
Set your environment:
❖ For csh or tcsh:
% source /LSF_TOP/conf/cshrc.lsf
❖ For sh, ksh, or bash:
$ . /LSF_TOP/conf/profile.lsf
Use lsfstartup to start the cluster.
Follow the steps in lsf7.0_lsfinstall/lsf_quick_admin.html to verify
that your cluster is operating correctly.
Have users run one of the shell environment files to switch their environment to the
new cluster.
