The LSF License File
This section helps you to understand the types of LSF licenses and the contents of the
LSF license file. It does not contain information required to install your license.
Evaluation (demo) license
You can use a demo license to install Platform LSF and get it running temporarily, then
switch to the permanent license before the evaluation period expires with no
interruption in service, as described in “Installing a permanent license for the first time”
on page 175.
Although there may be exceptions, a typical demo license:
◆ Is used during your free evaluation of LSF
◆ Expires on a preset calendar date (30 days after the license was generated)
◆ Is file-based (does not require Macrovision® FLEXnet™ software)
◆ Licenses all LSF products
◆ Allows an unlimited number of hosts to be LSF servers
Permanent license
Although there may be exceptions, a typical permanent license:
◆ Is granted when you purchase LSF
◆ Licenses specific LSF products that you have purchased
◆ Limits the number of hosts allowed to be LSF servers
◆ Requires FLEXlm™ 7.2 or later
◆ Is keyed to one or more specific FLEXlm license server hosts
◆ Does not expire
◆ Is not installed by lsfinstall; you must manually configure your permanent
license.
Enforcement of dual-core CPU licenses on Linux
Dual-core CPU hosts running Linux must be licensed by the lsf_dualcore_x86
license feature.
Each dual core processor requires one standard LSF license and one
lsf_dualcore_x86 license. Use lshosts -l to see the number of dual-core
licenses enabled and needed. For example:
% lshosts -l hostA
HOST_NAME: hostA
