Rolling Upgrade from RHEL7 to RHEL8
HiPerGator OS Upgrade: RHEL-7 → RHEL-8
HiPerGator has gone through a rolling upgrade process from Red Hat Enterprise Linux version 7 (RHEL-7) to version 8 (RHEL-8). The upgraded software environment includes updates to important components including, but not limited to, NVIDIA GPU drivers, CUDA (12.2), communication libraries, compilers (gcc/12 and intel/2023), and OpenMPI (4.1.5).
Some programs/workflows run in the updated software environment without any modification, and some require recompilation or adaptation.
Rebuilding Code for EL8
Note: PMIX v2 is no longer supported in EL8.
If you see an error regarding pmix v2, such as "error while loading shared libraries: libpmix.so.2: cannot open shared object file: No such file or directory", we recommend using the following environment modules to rebuild your code for EL8:
- gcc/12.2.0 openmpi/4.1.5
- cuda/12.2.2 gcc/12.2.0 openmpi/4.1.5
- intel/2020 openmpi/4.1.5
- cuda/12.2.2 intel/2020 openmpi/4.1.5
- nvhpc/23.7 openmpi/4.1.5
- cuda/12.2.2 nvhpc/23.7 openmpi/4.1.5
