Re: Nameless distro...

Broken, poorly tested, rushed, low quality....sounds like Mandrake to me...
The difference between a company that tests it's distros in house and fix test and polish before releasing (like SuSE) and companies like Mandrake that basically throw stuff together and dump it on the public for them to test and fix is apparent in this article. Mandrake uses the open source collaboration model to do their work, and then procedes to profit from it. While real companies like RH and SuSE actually pay people to do this testing before hand.
Also, take a look at a SuSE manual sometime, compare it to a Mandrake one. Again, the difference between professionals and amateurs is easily apparent.

It's fine that people love distros like Mandrake, and enjoy using and hacking on them, but it's inappropriate for these same people to push these rough, unpolished distros to new Linux users, and corporate customers. It just causes these people to have a bad taste in their mouth for Linux in general and doesn't further the Open Source cause.
Linux needs to be represented to these kinds of uptight users by grownups, with grownup products. Not by elite wannabe types screaming about how their Mandrake/Enlightenment desktop with the haxorz theme rules!

ULB with SLES8 is a fine representation of how things can be for people having the guts to stray off the Windows/Intel path.

"The HyperTransport (HT) buses are basically like very fast PCIX..."

HT came first. PCI-X is HT-like.

If people want to test 64 bit Linux simply run it on the P Mac G5. It can run 32 bit software too. And try Red Hat's libraries for the AltiVec math CPU in the G5. Interresting to see a test betwwen the PPC 970 and AMD 64!

There is a quite obvious link between the SuSE Linux people
and the ATI Linux developers. SuSE had ATI (better say
FireGL) drivers included on their Linux distribution for several
years now. Any such outraging project for getting the best,
fastest and latest hardwar run on Linux should considered
talking back to the expert people of really getting the best
that they can offer you - you just have to ask them,
but i strongly suppose you have not even tried it.

Can you play 'pong' with this setup?

Forget Pong. How well does it run vi?

The nameless x86-64 distribution is likely gingin64, Red Hat's technology preview, based on Red Hat Linux 9. It might have been SuSE Linux 8.2 beta or Red Hat Enterprise Linux 3.0 beta, but they haven't been out as long.

We've got one Opteron system at work, but it's tied up with 32-bit Windows and Linux compatibility testing. Eventually, we'll use it to test SuSE Linux Enterprise Server 8 and Red Hat Enterprise Linux 3.0. I can't wait for the Athlon 64 launch this Fall.

"and for your semolians you get ..."

I think that should be simoleons.

Ow! stop smacking me! I'll quit nit-picking!

I'm a systems architect and have been studying the Opteron for a while now. You have a misconception that I'd like to clear up.
The HyperTransport (HT) buses are basically like very fast PCIX buses and have nothing to do with the processor's access to memory. In fact, some Opteron CPUs have three HT buses, but only support dual interleaved memory configurations (requiring two DIMMs). You talk about how a system with one DIMM "simply uses only one of the two HyperTransport channels" but this is wrong. Both HT buses work fine, but only one of the memory channels is in use. In fact, all Opteron CPUs have this ability to use one or two memory channels. The BIOS is what makes configurations of the memory channels flexible enough to handle one DIMM or two. Apparently some BIOSes do allow this and some don't.

One more tidbit. In addition to the PCIX like functionality provided by the up to three HyperTransport buses, these buses can also serve as cache-coherency buses for the CPUs in the system. This means that all CPUs can share all of each others' memory in a way that allows their internal caches to transparently speed up accesses without ever seeing stale data due to the use of these caches. The CPU to CPU bandwidth over one HT bus peaks at 12.8Gb/s in each direction (assumes 800MT/s HT). This results in a hella-fast CPU to CPU communications path that will eventually cause the rethinking of a lot of strong assumptions in systems architecture about how symmetric multiprocessing systems should be built. It's very flexible and very very exciting.

White Paper
Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
