LSF stands for Load Sharing Facility, which is a workload management platform and job scheduler for distributed high-performance computing (HPC) by IBM. It provides a resource management framework that takes job requirements, finds the best resources to run the job, and monitors its progress. LSF can be used to execute batch jobs on networked Unix and Windows systems on many different architectures.

It is important to note that LSF can also refer to a Livestream Fail, which is a term used in the Twitch community to describe a clip of a streamer doing or saying something stupid, which is then posted on the /r/livestreamfail subreddit. However, in the context of computing and technology, LSF refers to the IBM workload management platform.

LSF is not related to Lutheran Services Florida (LSF), which is a non-profit organization that transforms lives by ensuring safe children, strong families, and vibrant communities.
