## [Introduction to Slurm-The Backbone of HPC](https://docs.rafay.co/blog/2025/04/10/introduction-to-slurm-the-backbone-of-hpc/)

This is part-1 in a blog series on [**Slurm**](https://slurm.schedmd.com/documentation.html). In the first part, we will provide some introductory concepts about Slurm. We are not talking about the fictional soft drink in the world of [Futurama](https://en.wikipedia.org/wiki/Futurama). Instead, this blog is about Slurm (Simple Linux Utility for Resource Management), an open-source, fault-tolerant, and highly scalable **cluster management** job scheduler and resource manager used in high-performance computing (HPC) environments.

Slurm was originally conceptualized in 2002 at [Lawrence Livermore National Laboratory](https://www.llnl.gov/) (LLNL) and has been actively developed and maintained especially by [SchedMD](https://www.schedmd.com/). In this time, Slurm has become the defacto workload manager for HPC with >50% of the Top-500 super computers using it.
