236 Platform LSF Command Reference
◆ Multi-user—By default, only root can start the LSF daemons. Any user can
submit jobs to your cluster. To make the cluster available to other users, you
must manually change the ownership and setuid bit for
lsadmin and badmin to
root, and the file permission mode to
-rwsr-xr-x (4755) so that the user ID bit
for the owner is
setuid.
Use the following commands to set the correct owner, user ID bit, and file
permission mode for a multi-user cluster:
# chown root lsadmin badmin eauth swtbl_api ntbl_api
# chmod 4755 lsadmin badmin eauth swtbl_api ntbl_api
After installing Platform LSF
1 Optional. Run hostsetup to configure host-based resources and set up
automatic LSF startup on your server hosts.
TIP: For Platform LSF HPC hosts, running hostsetup is optional on AIX and Linux. You must run
hostsetup on SGI IRIX, TRIX, and Altix hosts, and on HP-UX hosts.
a Log on to each server host as root. Start with the master host. If you are not
root, you can continue with host setup, but by default, only root can start
the LSF daemons.
b Run
hostsetup on each server host. For example:
# cd /usr/share/lsf/7.0/install
# ./hostsetup --top="/usr/share/lsf" --boot="y"
TIP: For complete hostsetup usage, enter hostsetup -h.
2 Log on to the LSF master host as root, and set your LSF environment:
❖ For csh or tcsh:
% source LSF_TOP/conf/cshrc.lsf
❖ For sh, ksh, or bash:
$ . LSF_TOP/conf/profile.lsf
3 Run lsfstartup to start the cluster.
TIP: For large cluster, where cluster management software exists, you should use /etc/init.d lsf
start instead of lsfstartup.
4 Test your cluster by running some basic commands (e.g., lsid, lshosts,
bhosts)
After testing your cluster, be sure all LSF users include
LSF_CONFDIR/cshrc.lsf or
LSF_CONFDIR/profile.lsf in their .cshrc or .profile.
Follow the steps in
lsf7Update3_lsfinstall/lsf_quick_admin.html for using
LSF_CONFDIR/cshrc.lsf and LSF_CONFDIR/profile.lsf to set up the
Platform LSF environment for users.
