PBS Pro is highly portable and should work on most modern Linux variants on x86_64 and ARM64 platforms. If you find that it doesn't work on one, please file a bug. The platforms that are tested automatically as part of the code contribution process are listed below. If you have tested on another platform, go ahead and add it.
While pre-built packages for OpenPBS are supplied for convenience for recent CentOS, Ubuntu, and openSUSE x86_64 platforms, OpenPBS is known to build and run on many more platforms including but not limited to:
RHEL and CentOS 7 and 8 on x86_64 and ARM64
SLES 12 and 15 on x86_64 and ARM64
Ubuntu 18.04 and 20.04 on x86_64 and ARM64
Ubuntu 16.04 on x86_64
