Funny how you've mentioned Ultra-high performance systems

Ten years ago very few "ultra-high performance systems" were using x86-based CPUs. Today... They own this space: 63% of systems from TOP500 are using Intel Xeons and AMD Opterons! The next biggest contender is PowerPC - and it's down to 17% already. Why ? People need ultra-fast CPUs not to brag about them but solve real tasks. And x86 makes it easier.
Note: these are custom-built system designed to run custom-built software on top of Linux (usually). So usual excuse that "it's just horrible Microsoft's OS that is driving back adoption of non-x86 CPUs" will not fly.
BTW: Debian is thinking about abandonment of the 11 primary architectures system - obscure architectures often break the only pair that matters (x86 and x86-64) so they'll eventually exclude most of them from "tier 1" support list...
Other distributions already gave non-x86 architectures "second class citizens" status...
