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 3.6 | OSG 23 |
|---|---|---|
| CentOS 7 | ✅ | |
| CentOS Stream 8 | ✅ | ✅ |
| CentOS Stream 9 | ✅ | ✅ |
| Alma Linux 8 | ✅ | ✅ |
| Alma Linux 9 | ✅ | ✅ |
| Red Hat Enterprise Linux 7 | ✅ | |
| Red Hat Enterprise Linux 8 | ✅ | ✅ |
| Red Hat Enterprise Linux 9 | ✅ | ✅ |
| Rocky Linux 8 | ✅ | ✅ |
| Rocky Linux 9 | ✅ | ✅ |
| Scientifix Linux 7 | ✅ |
OSG builds and tests its RPMs on the latest releases of the relevant platforms (e.g., in 2023, the RHEL 9 builds were based on RHEL 9.2).
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.
In addition, versions of RHEL/CentOS/SL 7 less than 7.8 do not have Python 3, which is required to run HTCondor 9 and HTCondor-CE 5.
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.
