Written with Platform LSF administrators in mind, this
brief provides a short explanation of significant changes in
Platform’s latest release of Platform LSF, with a specific
emphasis on scheduling and workload management features.
About Platform LSF 8
Platform LSF is the most powerful workload manager
for demanding, distributed high performance computing
environments. It provides a complete set of workload
management capabilities, all designed to work together to
reduce cycle times and maximize productivity in mission-
critical environments.
This latest Platform LSF release delivers improvements in
performance and scalability while introducing new features
that simplify administration and boost user productivity.
This includes:
• Guaranteed resources - Aligns business SLA’s with
infrastructure configuration for simplified administration
and configuration
• Live reconfiguration – Provides simplified administration
and enables agility
• Delegation of administrative rights - Empowers line of
business owners to take control of their own projects
• Fairshare & pre-emptive scheduling enhancements - Fine
tunes key production policies
Platform LSF 8 Features
Guaranteed Resources Ensure Deadlines are Met
In Platform LSF 8, resource-based scheduling has been
extended to guarantee resource availability to groups of
jobs. Resources can be slots, entire hosts or user-defined
shared resources such as software licenses. As an example,
a business unit might guarantee that it has access to specific
types of resources within ten minutes of a job being submitted,
even while sharing resources between departments. This
facility ensures that lower priority jobs using the needed
resources can be pre-empted in order to meet the SLAs of
higher priority jobs.
Because jobs can be automatically attached to an SLA class via
access controls, administrators can enable these guarantees
without requiring that end-users change their job submission
procedures, making it easy to implement this capability in
existing environments.
Live Cluster Reconfiguration
Platform LSF 8 incorporates a new live reconfiguration
capability, allowing changes to be made to clusters
1
without
the need to re-start LSF daemons. This is useful to customers
who need to add hosts, adjust sharing policies or re-assign
users between groups “on the fly”, without impacting cluster
availability or running jobs.
Changes to the cluster configuration can be made via the bconf
command line utility, or via new API calls. This functionality can
also be integrated via a web-based interface using Platform
Application Center. All configuration modifications are logged
for a complete audit history, and changes are propagated almost
instantaneously. The majority of reconfiguration operations
are completed in under half a second.
With Live Reconfiguration, down-time is reduced, and
administrators are free to make needed adjustments quickly
rather than wait for scheduled maintenance periods or
non-peak hours. In cases where users are members of
multiple groups, controls can be put in place so that a group
administrator can only control jobs associated with their
designated group rather than impacting jobs related to
another group submitted by the same user.
