Well, for one I'm just quoting facts, no more, no less. And yes, the
people evaluating mips/$ are not the IT staff (because they usually
don't even understand what the code does and how to find out where the
mips could be improved). You get scientists benchmarking the systems
with tuned gcc or assembly to see how the platfomr fits their
And once the system is found that will provide the nuerics for the
next 5-7 years the IT staff has to support it. AT that point it time
it doesn't matter if it will be running FC4, RHEL, SLES, Altrix or a
So, sitting as the IT staff manager on the other side and planning to
deploy F7 everywhere is not going to work. You only get to choose the
desktops and perhaps a smallish cluster. It's different in
experimental groups - there you get more power as an IT admin.
I'm not making this up, that's what I'm seeing in the last 18 years in
phys/chem (and it certainly wasn't better before that).
The question is will Fedora just say "we don't care, your IT
management model sucks", or will it try to keep this group happy? I
think it sounds more like the former, but whatever it is, we don't
really have to fight over their IT management system: Whether it
actually fits the surroundings or could be improved, we're not going
to change it, we're just either supporting it or not.
