OpenPBS vs schedulix

OpenPBS schedules jobs and manages workloads in high-performance computing environments, including clusters, clouds, and supercomputers. Its policy-driven scheduling balances job turnaround time and system utilization while selecting job placements. The system is designed for millions of cores and has been tested beyond 50,000 nodes. A plugin framework provides administration visibility and supports customized extensions. Health checks monitor faults and can mitigate them automatically; the fail-over architecture is designed to avoid a single point of failure and keep jobs running through failures. OpenPBS is self-hosted and free under the AGPL 3.0 open-source license, while PBS Pro is also dual licensed commercially. Public-sector organizations such as academic and research facilities generally choose the open-source license. Community help comes through a volunteer forum, without a guarantee of answers or bug fixes. OpenPBS is integrated into the OpenHPC software stack. The installation guide states that SELinux is not supported, and critical and high security fixes are delivered in the next major release.

Schedulix is open-source workload automation software for building and running IT process workflows. Its browser interface supports administration, workflow design, monitoring, and operations across systems. Scheduling can choose processes dynamically while accounting for priorities and available resources. Workflow structures include exit states, batch and job hierarchies, dependencies, resources, and triggers. Schedulix provides a documented API, and its RDBMS repository supports SQL read access through Standard Catalog Interface views. The product describes authentication for users, job server agents, and user processes, along with delegated system privileges and an audit trail of operator interventions. The maker says components restart without manual intervention after hardware, power, or operating-system failures, provided the RDBMS data remains secure. Source code is available on GitHub, and downloads include an RPM repository package and Windows packages. The software is free under the GNU AGPL and supports Linux, Windows, web, API, and self-hosted use. The maker also says users can move to proprietary BICsuite editions without losing work. Paid support eligibility is limited to installations from an unmodified official source copy or an independIT package.
