Platform Load Sharing Facility (or simply LSF) is a workload management platform, job scheduler, for distributed high performance computing. It can be used to execute batch jobs on networked Unix and Windows systems on many different architectures.[1][2] LSF was based on the Utopia research project at the University of Toronto.[3]


In 2007, Platform released Platform Lava, which is a simplified version of LSF based on an old version of LSF release, licensed under GNU General Public License v2.[4] The project was discontinued in 2011, succeeded by OpenLava.


In January, 2012, Platform Computing was acquired by IBM.[5]


The product is now called IBM Spectrum LSF. Its web page can be found at:

LSF Extensions and integrations


LSF extensions include:




DRMAA

The Distributed Resource Management Application API handles job management in a range of distributed resource management systems.

HPC Profile Basic

This describes how JSDL, Basic Execution Service (BES) and existing web services security mechanisms can be used interoperable to address batch job scheduling use case.

LSF Perl API

This comprises two modules, Base and Batch, allowing Platform's LSF APIs to be called by Perl.



  • Base module allows Perl applications to link the Load Information Manager (LIM) and Remote Execution Server (RES) daemons for LSF services e.g. retrieving system configuration and dynamic load information for distributed clusters hosts, task placement advice via LIM, and other related functions, thereby improving application performance and resources accessibility.

  • Batch module allows Perl applications to retrieve information as well as the submission of information about the hosts, queues, users, jobs and configuration of the batch system.



SAGA (Simple API for Grid Applications)

The SAGA C++ Reference Implementation provides an LSF plug-in (adaptor) for its standardized job submission, control and monitoring API. The API is available for C++ and Python.

Python LSF wrappers

LSF's API written in C can be easily accessed using Python. Several implementations of LSF Python APIs exist.[6]



LSF is one of the job scheduler mechanisms supported by the Grid Resource Allocation Manager (GRAM) component of the Globus Toolkit.

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy
