![]() ![]() Another called Grid Community Toolkit is also available but not really under active maintenance. One called Son of Grid Engine, which was maintained by the University of Liverpool and no longer is (for the most part). Forks of the last open source version soon appeared. It was then open sourced and maintained until an acquisition by Oracle took place, at which point they stopped releasing the source and it was renamed Oracle Grid Engine. It started as a closed source application released by Gridware but after their acquisition by Sun, it became Sun Grid Engine (SGE). Grid EngineĪ batch scheduler that has had a complicated history, Grid Engine has been known for being open source and also closed source. It was created by the Ohio Supercomputing Centre with a grant from the National Science Foundation. Open OnDemand is a user interface for SLURM that eases the deployment of workloads via a simple web interface. Not a scheduler per say, but deserves an honourable mention with SLURM. SLURM can currently be installed from the Universe repositories on Ubuntu. It’s used on about 60% of the TOP500 clusters and is the most frequently used job scheduler for large clusters. SchedMD are currently the main maintainers and provide a commercially supported offering for SLURM. Its development started as a collaborative effort between Lawrence Livermore National Laboratory, SchedMD, HP and Bull. Schedulers SLURM workload managerįormerly known as Simple Linux Utility for Resource Management, SLURM is an open source job scheduler. HPC workload reliance on performance has driven a lot of development efforts in Linux, all focused heavily on driving down latency and increasing performance anywhere from networking to storage. It drove Linux adoption from then onwards in government and expanded well outside that sector into others as well as enterprises. The first such cluster was deployed at NASA, which went on to shape HPC as we know it today. Beowulf clusters were essentially clusters created using commodity servers and high speed interconnect, instead of more traditional mainframes or supercomputers. NASA were early users of Linux and Linux, in turn, was fundamental to the first beowulf cluster. The Linux operating system, probably one of the most recognised open-source projects, has been both a driver for open source software in HPC and been driven by HPC use cases. Containers: LXD, Docker, Singularity (Apptainer) and Charliecloud.Workloads: BLAST, OpenFOAM, ParaView, WRF and FDS-SMV.Cluster provisioners: MAAS, xCat, Warewulf.Libraries for parallel computation: OpenMP, OpenMPI, MPICH, MVAPICH.Schedulers: SLURM, OpenPBS, Grid Engine, HTCondor and Kubernetes.These are some of the types of open-source tools typically used for HPC: There are a lot of open-source projects in HPC, which makes sense as its foundations were mostly driven by governmental organisations and universities (some of the primary consumers of open source). ![]() What kind of open-source software is there in HPC? ![]() High-performance computing (HPC) technologies – what does the future hold?.High-performance computing cluster architectures – An overview of HPC cluster architecture.What is supercomputing?
