Yeah, I am aware of that, but Linux distros package very old versions, and we need to be able to support multiple for users. Realistically, academic researchers like to use 'bleeding edge' type things. Generally a big HPC cluster comes with RHEL too and a support contract, because you need the drivers for the hardware - things like Infiniband networking, etc. so switching distro isn't an option really.

Linux does seem to have some open source Infiniband drivers, but maybe not for the ones you own, or maybe the proprietary ones are faster. https://wiki.gentoo.org/wiki/InfiniBand https://wiki.gentoo.org/wiki/InfiniBand https://wiki.archlinux.org/title/InfiniBand https://wiki.archlinux.org/title/InfiniBand https://pve.proxmox.com/wiki/Infiniband https://pve.proxmox.com/wiki/Infiniband
