Generally when a system is selected to be on the Top500 list after
benchmark verification someone at the facility, usually the director
or such, gets a request for system information. Generally any distro
of Linux is put down as just "Linux". I've worked on several systems
on the lists over the years, with many different distros, and they all
get listed as Linux. If you were more specific such as Scientific
Linux, then the list of OS's would balloon since you would have people
putting in RHEL, RedHat, RedHat Enterprise, CentOS, CentOS 4, CentOS
5, etc... There are already listed on the list 5 different releases of
Suse, and 3 of RedHat. And then you have the case of some Unix
variants, such as HP, being called Linux. The problem is there is no
standardization for the question of OS. It just says "OS", and the
site can enter in whatever they want. It would make more sense to list
a distro and no versioning numbers.

The J/PSI cluster (#141 on the new TOP500 list) is indeed running
Scientific Linux 4.4. Perhaps the reason it shows as Linux is that
when one uses 'uname -a' it does not show much detail. I am pretty
sure Don submitted our results to the TOP500 and he may be able to
explain how this data field is populated.

The J/PSI cluster at Fermilab is listed as running "Lunix",
and I believe that it is running Scientific Lunix.
Don and/or Amitoj can comment further...

I'm at SC09 this week. Awesome hardware, awesome people. The
Top500 for the month was announced, Linux runs on 446+ of them,
no surprise there.
What is a surprise is the nonappearance of Scientific Linux on
this list:

I would assume SL would be running on many, if not most, of the
big iron X86 array systems. I would also assume more celebrity
SL deployments means more funding for our heros at Fermi. Is
this a "don't ask, don't tell" thing?
