CentOS - Oct 2005 - Is CentOS 3.5 built out of RHEL AS OR ES?

Hello Gurus,
  1. Do you have any idea whether CentOS 3.5 is built out of RHEL AS or RHEL
ES?

2. Can a single process use more than 32 Gbytes of RAM in CentOS 3.5 ?
 Is there any limitation that you experienced?
 Thanks for your time.
 Siva.

Neither.
The main difference between AS and ES is the support service. There
are also some changes on the package set. On that case, either
the software is non-distributable (so can't be on CentOS), or it is
on the RHEL source tree (and on CentOS).

Cya,

The SRPMS are the same for both AS and ES.  We build with no artificial
restrictions to number of CPUs, etc. So CentOS is comparable to AS from
that point of view.

According to <http://www.redhat.com/en_us/USA/rhel/details/limits/>, 
RHEL3's max memory on i386 and x86_64 is 64GB.  On x86_64, I don't know
of
anything limiting a process to using as much of that as it can get (that 
doesn't mean that there isn't a limit, but I don't know that there
is).
On i386, of course, you'll get only ~4GB/process.

And if you're running x86_64, I'd strongly recommend centos 4 (which has
the same limits).

It is built out of RHEL 3.0 SRPMS. I have downloaded and installed them 
for a specific purpose where only RHEL 3.0 was required and it works 
very well.
