I'm spec-ing a development server for some Haskell hackers. In particular, they need to be able to build and run the Glasgow Haskell Compiler (ghc), the x86_64 port of which isn't quite there yet.
My current thought is to get an Opteron-based system, but load it (initially, at least) with the 32-bit i386 version of CentOS. That buys me near-term ghc compatibility. In the future, should ghc become 64-bit clean, I'll be able to upgrade to a full 64-bit OS.
The alternative is to build the server around high-end ia32 chips and leave the Opteron for another day.
Does anyone have experience running a 32-bit-only OS on Opterons? Are there any gotchas?
I planned on doing a similar thing until I found that for some reason, cool & quiet does not seem to work unless in 64 bit mode under linux at least. I decided to go 64 bit because the server was going to be running in my garage and I wanted it as cool as possible.
Has anyone managed to get CPU Throttling/CNQ working on a 32bit linux ?
Bards.
