Floating Client Licenses
176 Administering Platform LSF
Administration
commands
Since LSF floating client hosts are not listed in lsf.cluster.cluster_name, some
administration commands will not work if issued from LSF floating client hosts.
Always run administration commands from server hosts.
Floating client hosts and host types/models
This differentiates between client hosts and floating client hosts in terms of the
restrictions on host types or models.
For LSF client hosts, you can list the host type and model in
lsf.cluster.cluster_name and by default, restrict running applications on
different host types.
For floating client hosts, host types and models are not included in the client
information. By default, any job submissions made from floating client hosts are
allowed dispatch to any host type or model.
In the same way as client and server hosts, you can specify a specific model or type
when you submit a job from a floating client host.
For example:
bsub sleep
The command above is interpreted as:
◆ -R "type==local" on a client host
◆ -R "type==any" on a floating client host
Install LSF floating client licenses
If you believe that the use of floating client licenses is appropriate for your needs,
follow this procedure to install LSF floating client licenses.
1 Obtain the floating client license.
This is similar to getting any other license. See Getting a permanent license on
page 159.
2 Update your license file. Add the appropriate license line in the license file
license.dat. The LSF license must contain FEATURE lines for
LSF_Float_Client.
Although LSF Floating Client requires a license, LSF_Float_Client does not
appear in the
PRODUCTS line. LSF_Float_Client also cannot be added as a
resource for specific hosts already defined in
lsf.cluster.cluster_name.
Should these lines be present, they are ignored by LSF.
3 Define server hosts in
lsf.conf.
As with any client host, specify the parameter LSF_SERVER_HOSTS in
lsf.conf to define LSF server hosts for the LSF client hosts to contact.
4 Edit
lsf.cluster.cluster_name by adding or uncommenting the
FLOAT_CLIENTS parameter in the
Parameters section:
