I call crap on that. I was a single systems person for a bunch of
systems for a long time. You keep your sanity by enforcing policy and
you can do that by using the tools available to you to simplify the
tasks. You don't need homogeneous hw, you need LARGELY homogeneous hw.
Well, I used the phrase RATHER homogeneous hw, so we're not that far
So you limit the processor archs and you try to focus things down as
much as possible.
It took me 2 years to get rid of all the sun crap in the physics
department but I did.
Which implies that you had enough resources (or cheap enough hardware)
to replace these machines in a two year turnaround. That's what I call
a high budget. Any mpp system I have used had a turnaround of at least
5-7 years, they do have 8 digit $/€ costs after all.
I still had wacky AXP crap after that but then another few years and
that was gone, too.
My point is it didn't have much to do with the distro,
No, the discussion is not about the distro at all: It is about
acknowledging that phys/chem institutions and academia do not have the
luxury of a flat same-hw-same-os infrastructure for various reasons,
be that due to the project's constraints (at DESY we've been
developing our own set of VLIW processors), separation of development
and number crunch systems/clusters, exchange across the institutional
border in scientific networks, different ages of the distro, and what
else has been said in this thread.
US/Japan have a better budgeting in IT infrastucture, that's an
ongoing joke among European/Russian physicists. So Duke may have given
you a different impression.
it had more to do with me finding and working policy in place where
it needed to happen. and THAT is how a sysadmin survives and
thrives. By learning where they can engineer around a solution and
where they need to use policy to help themselves.
In this case Bill is right, this is where we realize that we can
make the engineering help get rid of years of bad policy.
The reality is that you will not chnage these structures and that
these users will pick what distro suits them. If it becomes harder and
harder to run their codes on Fedora and RHEL then they will check for
alternatives, and not wait for the next generation solution to show up.
