IBM Platform LSF Server v9.1.3
IBM Platform LSF is a powerful workload management platform for demanding, distributed High Performance Computing (HPC) environments. It provides a comprehensive set of intelligent, policy-driven scheduling features that enable you to utilize all of your compute infrastructure resources and ensure optimal application performance.
LSF Server host is a server that is capable of submitting and executing jobs. They cannot be selected as LSF Master incase the designated LSF Master goes down.
More information available at the IBM Knowledge Center
Please note that the LSF charms (LSF Storage, LSF Master and LSF Server) will create LSF cluster having same host type (either x86 or ppcle). LSF supports different host types to be part of LSF Cluster. But the LSF charms as of now supports same host type model only (So all the hosts ie master, server should have same machine architecture either x86 or ppcle).
This charm will not download or require any LSF product binaries as that is being handled by the
IBM Platform LSF Storage charm.
The LSF installation/configuration files will be shared when a relation is added between LSF Storage and LSF Server (using NFS).
This charm will deploy only LSF Server. Functionally this charm will do nothing. To have a working LSF Cluster, you need to add relations between LSF Server and LSF Storage and between LSF Server and LSF Master.
To deploy IBM Platform LSF Server charm, follow the below steps:
1) Deploy the LSF Storage charm
juju deploy ibm-platform-lsf-storage \ --resource ibm_lsf_installer=</path/to/installer.tar.Z> \ --resource ibm_lsf_installation_x86=</path/to/distribution.tar.Z> \ --resource ibm_lsf_entitlement_file=</path/to/entitlement.dat>
Note: The resource for getting the Installation/Distribution is different for x86 and Power, so if you are deploying on x86 machines, use resource name as
ibm_lsf_installation_x86 and for Power as
2) Deploy the LSF Master charm
juju deploy ibm-platform-lsf-master
3) Deploy the LSF Server charm
juju deploy ibm-platform-lsf-server
4) Add a relation between LSF Storage and LSF Master and LSF Storage and LSF Server to share the LSF installation and configuration files
juju add-relation ibm-platform-lsf-storage ibm-platform-lsf-server juju add-relation ibm-platform-lsf-storage ibm-platform-lsf-master
5) Add a relation between LSF Master and LSF Server.
juju add-relation ibm-platform-lsf-master ibm-platform-lsf-server
Add units of LSF Server
juju add-unit ibm-platform-lsf-server
This will add one more LSF Server host to your existing LSF Cluster.
Remove units of LSF Server
juju remove-unit <unit name of the LSF Server you want to remove>
This will remove the unit from the existing LSF Cluster. (LSF conf files will be updated and LSF files will be unmounted)
A LSF Server is related to IBM Platform LSF Storage charm as well as IBM Platform LSF Master charm. In case you want to remove the relation between these, refer to the below steps:
juju remove-relation ibm-platform-lsf-master ibm-platform-lsf-server
This will remove the server host information from the lsf configuration files and the server host will no longer be part of the existing LSF Cluster. The LSF Server Daemons will be stopped.
juju remove-relation ibm-platform-lsf-storage ibm-platform-lsf-server
This will unmount the LSF shared installation files.
Verify the LSF Cluster
Once the IBM Platform LSF Server is deployed successfully and relation is established between LSF Storage and LSF Server and LSF Master and LSF Server, you can verify your LSF cluster by running some lsf commands as mentioned below:
Login into the machine where LSF Server is installed as lsf administrator user
Export the lsf profile path:
Go to the path
/usr/share/lsf/9.1/linux2.6-glibc2.3-x86_64/bin. The distribution folder will change based upon Operating System, for Power the path would be
/usr/share/lsf/9.1/linux3.10-glibc2.17-ppc64le/binand you can issue commands like
bhoststo verify your cluster is up and fine.
For submitting jobs you can issue command
<job>, for example:
