An HPC workload manager and job scheduler for desktops, clusters, and clouds.
If you are new to this project, please start at https://www.openpbs.org/
Note: In May 2020, OpenPBS became the new name for the PBS Professional Open Source Project. (PBS Professional will be used to refer to the commercial version; OpenPBS to the Open Source version -- same code, easier naming.) As there are many parts to the project, it will take several weeks to change the name in all places, so you will continue to see references to PBS Pro -- stay tuned.
OpenPBS® software optimizes job scheduling and workload management in high-performance computing (HPC) environments – clusters, clouds, and supercomputers – improving system efficiency and people’s productivity. Built by HPC people for HPC people, OpenPBS is fast, scalable, secure, and resilient, and supports all modern infrastructure, middleware, and applications.
OpenPBS is a community effort and there are a variety of ways to engage, from helping answer questions to benchmarking to developing new capabilities and tests. We value being aggressively open and inclusive, but also aggressively respectful and professional. See our Code of Conduct.

OpenPBS is also integrated in the OpenHPC software stack. The mission of OpenHPC is to provide an integrated collection of HPC-centric components to provide full-featured HPC software stacks. OpenHPC is a Linux Foundation Collaborative Project. Learn more at:
There is a huge opportunity to advance the state of the art in HPC scheduling by bringing the whole HPC world together, marrying public sector innovations with private sector enterprise know-how, and retargeting the effort wasted re-implementing the same old capabilities again and again towards pushing the outside of the envelope. At the heart of this vision is fostering common standards (at least defacto standards like common software). To this end, Altair has made a big investment by releasing the PBS Professional technology as OpenPBS (under an Open Source license to meet the needs of the public sector), while also continuing to offer PBS Professional (under a commercial license to meet the needs of the private sector). One defacto standard that can work for the whole HPC community.
