PBS Professional= =C2=AE software optimizes job scheduling and workload management in high-pe= rformance computing (HPC) environments =E2=80=93 clusters, clouds, and supe= rcomputers =E2=80=93 improving system efficiency and people=E2=80=99s produ= ctivity. Built by HPC people for HPC people, PBS Pro=E2=84=A2 is fast, scal= able, secure, and resilient, and supports all modern infrastructure, middle= ware, and applications.
We released Altair PBS Professional under an open source license=E2=80=
=A6 why?
More than 25 years ago, Bill Nitzberg was just starting his career in HPC a=
t NASA, where, along with a great team, he developed the original PBS softw=
are. Today, Altair PBS Professional is among the most-used technologies for=
HPC job scheduling.
But scheduling is hard =E2=80=94 every site has unique processes, unique go=
als, and unique business requirements. Too often effort is duplicated acros=
s public and private sectors as functionality is replicated in open source =
and closed source products. So in 2016 Altair made a big investment toward =
uniting the whole HPC community to accelerate the state of the art (and the=
state of actual production operations) for HPC scheduling. We released Alt=
air PBS Professional under an open-source license, opening the core of the =
software to the community.
PBS Professional=C2=AE, continues to be available as a hardened,=
commercial version for commercial customers, but alongside that offering w=
e are committing to being open and community oriented. We are focused on lo=
ngevity =E2=80=93 creating a viable, sustainable community to focus on job =
scheduling software that can truly bridge the gap in the HPC world. We cont=
inue to contribute to the Open PBS code base with updates from the core PBS=
Professional product and adopt community improvements from Open PBS as wel=
l.
Obviously, we cannot do this alone! Please join us as part of the PBS Pro c=
ommunity.
OpenPBS is a community effort and there are a variety of ways to engage,= from helping answer questions to benchmarking to developing new capabiliti= es and tests. We value being aggressively open and inclusive, but als= o aggressively respectful and professional (see our Code = of Conduct).

There is a huge opportunity to advance the state of the art in HPC sched= uling by bringing the whole HPC world together, marrying public sector= innovations with private sector enterprise know-how, and retargeting the e= ffort wasted re-implementing the same old capabilities again and again towa= rds pushing the outside of the envelope. At the heart of this vision = is fostering common standards (at least defacto standards like common softw= are). To this end, Altair has made a big investment by releasing PBS = Pro under an Open Source license (to meet the needs of the public sector), = while also continuing to offer PBS Pro under a commercial license (to meet = the needs of the private sector). One defacto standard that can work = for the whole HPC community.
