Yesterday on the Fedora devel mailing list a message was posted entitled "ARM is a dead end." This independent user felt like saying ARM is dead now that Intel has out their first Atom x86-based smart-phone. Here's the rest of the (comical) message:
So even smartphones are going x86 now. It looks like x86 is going to defeat ARM just like it defeated all the previous attempts at changing the instruction set, even Intel's own IA-64. The fastest x86 CPUs are still worlds faster than the fastest ARM CPUs. This new smartphone's single-core Atom is competitive in speed with other smartphones' multi-core ARMs.There's been many responses, a majority of which have been in favor of Fedora continuing to support the ARM architecture and users not seeing ARM hardware vanishing any time soon. The original poster has yet to respond to any of the comments generated, but if you want an interesting Friday afternoon read, check out the thread.
So I would urge Fedora not to waste our time on a low-end architecture filling a temporary niche which will become obsolete as demand for performance increases. We should rather support only one primary architecture (x86, i.e.: x86_64, and legacy i686 as long as there's a need for it) and support it well, as we have done since we finally got rid of the legacy PPC burden. Niche architectures are exactly what secondary architectures are for.
There's also the 12-core Ubuntu Linux ARM cluster benchmarks I published yesterday as some additional Friday afternoon reading for those interested in ARM on Linux.
