Upgrade and Compatibility Notes

What’s new in Platform LSF License Scheduler Version 7 Update 4

For detailed information about what’s new in Platform LSF License Scheduler Version 7, visit the Platform Computing Web site to see Features and Benefits.

LSF compatibility

Platform LSF License Scheduler Version 7 is compatible with LSF 7, and LSF 6.x servers.

System requirements

See the Platform Computing Web site for technical information about supported operating systems and system requirements for Platform LSF License Scheduler.

What’s Changed in Platform LSF License Scheduler Version 7

Changed behavior

Flexible grid interface plugin

The Platform LSF License Scheduler flexible grid interface license management plugin is no longer supported.

License Scheduler failover daemon

The License Scheduler failover daemon (FOD) is a daemon running under Platform LSF License Scheduler that provides failover support for blcollect by controlling and monitoring the blcollect instances. If a blcollect instance aborts, the failover daemon starts up a new blcollect instance. The failover daemon itself runs on the master host and is protected by master host failover.

Since the failover daemon controls blcollect, you can only shut down blcollect by shutting down the failover daemon.

The Platform LSF License Scheduler failover daemon package is a part of the Platform LSF License Scheduler Version 7 Update 4, and can be found in the fod subdirectory of the License Scheduler distribution file. See the README file in the fod subdirectory for more information.

License token distribution by demand

License Scheduler Update 4 introduces a new algorithm to distribute tokens to projects based on configured share account of projects instead of considering all projects regardless of their demand for tokens. License Scheduler now takes projects with demand into account. Projects without demand are excluded. See Using Platform LSF License Scheduler for an example of how licenses are shared according to the share assignment ratio when there is demand.

No configuration parameters or environment variables are new or changed for LSF License Scheduler Version 7 Update 4.
