-LSF (Platform Load Sharing Facility) is a job [[scheduler]]. It is responsible for monitoring and controlling the workload of the batch system of a supercomputer and assigns resources to jobs. This system is aimed at bigger applications that need a lot of resources in terms of memory and execution time and cannot be directly accessed by the user, as opposed to [[Nodes#Login|login nodes]]. Applications to execute have to be specified in a [[jobscript]] that is submitted to the batch system by the user via a scheduler (like LSF).

 LSF is a job [[Scheduler|scheduler]]. The abbreviation stands for "Platform Load Sharing Facility", which is used to monitor and control the workload of the batch system of a supercomputer and to assign resources to jobs. This system targets applications that utilize a lot of resources regarding memory and computation time. It cannot be directly accessed by the user, as opposed to the [[Nodes#Login|login nodes]]. Applications to execute have to be specified in a [[Jobscript|jobscript]] that is sent to the batch system by the user.
