pbsproOpen source licensing for Altair’s market-leading HPC workload manager, PBS Professional, is now available. PBS Pro development communities are now forming and the full-core open source version of PBS Pro can be downloaded at

Our intent is to continuously push the boundaries of HPC to pursue exascale computing through active participation with the HPC community,” says James R. Scapa, Altair’s Founder, Chairman, and CEO. “Working together toward common goals will allow for resources to be applied more efficiently. Our dual-licensing platform will encourage public and private sector collaboration to advance globally relevant topics including Big Data, cloud computing, advanced manufacturing, energy, life sciences, and the inexorable move toward a connected world through the Internet of Things.”

With the release of this Open Source Initiative compliant version, PBS Pro will support an environment of collaboration for the HPC community to combine efforts and focus on achieving common objectives for high-performance computing. PBS Pro has been commercially developed and supported for over twenty years, with thousands of organizations worldwide using its award-winning scalable workload management platform to improve the efficiency and throughput of their computational infrastructure.

The PBS Pro open source licensing option complements the public sector’s culture of collaborative innovation and provides a robust platform for engineers, researchers and scientists in different organizations to work, learn and advance HPC together. The private sector will continue to have access to a fully supported, hardened HPC workload management platform tightly integrated with Altair’s PBS Works suite and its hardware and software partner technologies.

Scheduling is a basic building block of HPC. We are trying to cultivate a community that spans the world of HPC (both public and private sectors) to eliminate duplication, to build on the strengths of all sectors, and to focus on a common solution for HPC scheduling. A shared solution will speed up progress for all,” remarked Dr. Bill Nitzberg, PBS Works CTO. “Altair is committed to being aggressively open and community-oriented with this project and looks forward to nurturing an inclusive environment for the advancement of HPC.”

In parallel with the open source release of PBS Pro, Altair continues to work closely with the Linux Foundation and is a proud founding member of the OpenHPC Collaborative Project. Through this collaboration, PBS Pro can be leveraged in the OpenHPC software stack and Scott Suchyta, Director of Partner Solutions and Integrations at Altair, will be a supporting member of the OpenHPC Technical Steering Committee (TSC). As part of the committee, he will work with fellow TSC members to provide an open and transparent collaborative development of the project’s direction and code contributions.

The global HPC community is invited and encouraged to engage, participate and share in the PBS Pro open source project. Join the conversation and downloads of PBS Pro are available at
