Supported Platforms

The OSG release series are supported on Red Hat Enterprise Linux (RHEL) compatible platforms for 64-bit Intel architectures according to the following table:


As of July 2020, only of a subset of the software stack is supported on RHEL 8-compatible platforms. The full software stack will be supported by the end of 2020. You can track packages released for EL8 through our release notes.

Platform OSG 3.5 OSG 3.4
CentOS 6
CentOS 7
CentOS 8
Red Hat Enterprise Linux 6
Red Hat Enterprise Linux 7
Red Hat Enterprise Linux 8
Scientific Linux 6
Scientifix Linux 7

OSG builds and tests its RPMs on the latest releases of the relevant platforms (e.g., in 2018, the RHEL 7 builds were based on RHEL 7.5). Older platform release versions may not receive thorough testing and may have subtle bugs. In particular, versions of RHEL/CentOS/SL 7 less than 7.5 have known issues with several pieces of software, including osg-oasis and xrootd-lcmaps. If sites run into problems with one of those versions, we will ask them to update to the latest operating system packages as part of the support process.
