HP XC System Software Administration Guide Version 2.1

• HP OEM licensing is configured.
HP O EM licensing is enabled in LSF-HPC by adding the follow ing string to the LSF-HPC
configuration file, /opt/hptc/lsf/top/conf/lsf.conf. This tells LSF-HP C
where to look for the shared object to interface with HP OEM licensing.
XC_LIBLIC=/opt/hptc/lib/libsyslic.so
• Access to L SF-HPC from every node in the clus
ter is configured.
Configuring all nodes in the HP XC system as LSF-HPC floating client nodes makes
available access to L SF-HPC from all nodes. Two files are edited to perform this
configuration:
-AddingLSF_SERVER_HOSTS="lsfhost.localdomain" to the lsf.conf
configuration f ile.
-AddingFLOAT_CLIENTS_ADDR_RANGE=172
.20 on its own line in the Parameters
Section of the file /opt/hptc/lsf/top
/conf/lsf.cluster.clustername.
The FLOAT_CLIENTS_ADDR_RANGE value (in this case 172.20) must
be the management network IP address range that is configured for the HP
XC system. This value should be equal to t he value of nodeBase in the
/opt/hptc/config/base_addr.ini file .
The HP X C system /etc/hosts file has an entry for lsfhost.localdomain,which
allows the LS F-H P C installation to instal l itsel f w it h the name lsfhost.localdomain.
The /opt/hptc/lsf/top/conf/hosts fil e maps lsfhost.localdomain and
its virtual I P to the designated L SF execution h ost
•AninitialLSF-HPChosts file to m
ap the virtual hostname (lsfhost.localdomain)
to an actual nodename is provid
ed.
• Sets the default LSF-HPC environment for all users who log into the HP XC system.
Files named lsf.sh and lsf.csh areaddedtothe/etc/profile.d/ directory;
these files source the respective /opt/hptc/lsf/top/conf/profile.lsf and
/opt/hptc/lsf/top/conf/cshrc.lsf files.
•TheJOB_ACCEPT_INTERVAL= e
ntry in the lsf.params file is set to 0 (zero) to allow
more than one j ob to be dispat
ched to the LSF-HPC execution host per dispatch cycle. If
this setting is nonzer o, jo
bs are dispatched at a slower rate.
• A soft link from /etc/init.d/lsf to /opt/hptc/sbin/controllsf is created.
12.3 LSF-HPC Startup and Shutdown
The following sections di
scuss starting up and shu tti ng do wn LSF-HPC.
12.3.1 Starting Up LSF
LSF-HPC is config ured to s
tart up automatically when the HP XC system starts up through
the use of the /etc/init
.d/lsf script.
Should LSF-HPC stop running, you can start it with the controllsf command as shown here.
# controllsf start
This command searches th
rough a list of nodes with the lsf service until it finds a n ode to
run LSF-HPC.
Alternatively, you can invoke th e following command to start LSF-HPC on the current node.
# controllsf start here
