Restart with LSF reconfiguration

Strict project name checking

If LSF_LIC_SCHED_STRICT_PROJECT_NAME=y in lsf.conf, jobs submitted with misspelled project names are rejected rather than submitted to the default project.

Installation

When installing License Scheduler standalone, the installer removes EGO environment variables from cshrc.lsf and profile.lsf. Specify a different LSF_TOP from the LSF installation to install standalone License Scheduler.

Preemption

If the LSF administrator has defined JOB_CONTROLS in lsb.queues so that preemption uses the signal SIGTSTP, they must also define LIC_SCHED_PREEMPT_STOP=Y in lsf.conf for License Scheduler preemption to work.
