Have you considered FreeBSD?

I love Linux and I and used it on my desktops and notebooks exclusively for 10 years. Having said that to hopefully avoid any flame wars, in recent years I have started to use FreeBSD on servers. It is a small learning curve for Linux users, but you will be rewarded by the incredible stability and reliability of FreeBSD.

FreeBSD offers its unique Jails feature, similar to but not the same as VMs. Jails, the ZFS and the new package management tools are making FreeBSD an easy choice for servers. No other OS offers Jail technology and few offer the ZFS.

To make the transition easier, look at PC-BSD. This is a project to bring FreeBSD to the desktop (and would be serious competition for Linux if FreeBSD offered better video and other hardware support) but PC-BSD can be used to install plain FreeBSD for a server and offers a command-line utility, the warden, to manage Jails.

I am using SL to type this of course, but we Linux users should be aware of FreeBSD and PC-BSD.

Cheers, Bill

It's hard to tell a feature set from the SL kernel version. TUV will
have all kinds of backports in there, and it could well include what
you are looking for. A quick google pulls up a bunch of reports saying
that (for example) RHEL 6.2 added support for Bulldozer opterons.

On the topic of compilers... a while back was the announcement of the
"Red Hat Developer Toolset"; at the time I remember Connie said she was
working on it. I'm not sure if I missed an announcement, but did that
ever work out for release on SL?
