The LSF License File
You must have a valid license to run LSF. 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.
TIP: To learn about licensing license a cluster that includes Windows hosts, see Using Platform LSF
on Windows.
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 on page 158.
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® FLEXlm™ 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
Enforcement of dual-core processor licenses on Linux
Dual-core processor 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 hostB
HOST_NAME: hostB
