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:

Platform OSG 3.5 OSG 3.4
CentOS 6
CentOS 7
Red Hat Enterprise Linux 6
Red Hat Enterprise Linux 7
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.
