Platform LSF Administration Guide Version 6.2

Welcome
Administering Platform LSF
17
Since the total file size of the info directory is divided among its subdirectories, your
cluster can process more job operations before reaching the total size limit of the
job files.
◆ Improved job forwarding for remote Platform LSF MultiCluster resources—
Job submission forwarding policy can now consider remote resource availability
before forwarding jobs. This allows more jobs to be forwarded because more
resources are available, and reduces the number of pending jobs on the remote
execution cluster.
To enable to submission forward policy to consider remote resource availability,
define MC_PLUGIN_REMOTE_RESOURCE=y in
lsf.conf.
◆ Support for dual-core CPUs—Platform LSF can detect Linux hosts with dual-
core CPUs and use the detected number of CPU cores on the host instead of the
number of physical CPUs. LSF scheduling policies use that value for job scheduling.
For a dual-core host,
lshosts shows the number of cores under ncpus instead of
physical CPUs.
To enable job scheduling based on dual-core CPU information for a host, define
LSF_ENABLE_DUALCORE=Y in
lsf.conf.
To make use of dual-core CPUs for scheduling, hosts must have the
lsf_dualcore_x86 license feature enabled. 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.
Platform LSF on Windows enhancements
◆ IBM Rational ClearCase Support—Extends current support for UNIX on IBM
Rational ClearCase to include Linux and Windows support.
◆ Silent installation—Automate the installation and upgrade of a large number of
Windows-based Platform LSF clusters in a batch mode.
Usability
◆ Open advance reservation—Ensure higher resource utilization by guaranteeing
the right resources are allocated to the right jobs by allowing jobs to continue to run
once their reservation has expired.
◆ Condensed host group configuration—Ease the administration of large host
groups by using wildcard characters and other special characters to configure hosts
that belong to different groups - including a condensed view of host group statistics.
◆ Accounting and notification of Platform LSF product license overuse—
Platform LSF tracks the peak usage of Platform LSF family licenses and writes
accounting information to the license usage account file
lsf.cluster_name.license.acct.
If LSF_LICENSE_NOTIFICATION_INTERVAL is set in
lsf.conf,
notification email is sent to the primary cluster administrator about license overuse.
