All,

The Beta release of the 32-bit (i686) Architecture of CentOS-7 (1503) is
currently on build logs.


Right now, only the boot.iso is available, but after some testing from
the users here with feedback, we can spin another tree with fixes and
actual installer isos.

http://buildlogs.centos.org/centos/7/os/i386/

updates are also here:

http://buildlogs.centos.org/centos/7/updates/i386/

Current known issues are:

1. If installing on a QEMU (kvm) i386 VM, you must modify the VM cpu to
use "copy host cpu"

2. The gnome desktop will not exit or log out from the menu.

Some Cloud providers actually prefer the 32-bit OS because they can squeeze more performance out of less memory... at least with CentOS 6.x.

Ward, are you saying that if you are using one of the minimal cloud configs with 1 CPU and 512Mb, that you get better performance from the 32-bit as opposed to the 64-bit versions?

I'm the wrong one to ask. @rentpbx uses 32-bit images. Perhaps they can comment as to why.

In case you ever tried to run Linux (and then, software applications on top of it) on PowerPC or Sparc, then you'll understand that working with a deprecated distribution on a deprecated architecture leaves you on your own. Support disappears quicker than you can say "Sun Micro-who?"

It's not the end of i386 completely, yet, but the warning shots were fired long ago and now they're even printing it in the news.

What is the support ''end of life'' for each CentOS release?


Code:
CentOS-7 updates until June 30, 2024

Great. Now tell me about the 32-bit support plan for all of those libraries and apps that go into an Incredible PBX system.

I don't know. What uses arm32?

If there's still hardware being produced that uses that architecture, and it's not completely obscure, you should be good to go for a while.

The reason that distributions and applications are going to start dropping i386 support is that desktop, laptop, and server manufacturers aren't shipping machines with 32-bit processors anymore. A brief Google search told me that the last 32-bit chip from Intel was the Pentium 4. So it's been a while.

raspberry pi, yes the raspberry pi 3 is 64 bit, but the amount of raspberry pi 1 and 2 out there with only 32 bit architecture means that 32 bit is going to be around for a while.

the last 32 bit x86 chip was a celeron if I remember correctly, either intel atom or whatever was in the eeepc 701sd

This is why I love 32-bit operating system for a puny little 512MB pbx virtual server.
For PHP (which the freepbx pbxinaflash incrediblepbx web interface is running on), a 64 bit operating system causes the PHP memory usage to be 2x up to 3.5x compared to the 32 bit operating system. On 32 bit, PHP is much less demanding of memory, so, it will hit the swap file less often, and feel faster.
Source: "comparing 32bit to 64bit systems, memory consumption increases by 100-230 percent."
http://we-love-php.blogspot.com/2012/06/php-memory-consumption-with-arrays.html

Not to mention how Apache, MySQL (MariaDB), and Asterisk, also use more of your precious 512MB memory on 64-bit, and less on 32 bit. Why waste RAM and be bogged down by slow swap to disk? Nobody has given me a good enough reason..... yet !

Anyone else heard of PUIAS?

https://springdale.math.ias.edu/

Springdale Linux (SDL) / Formerly known as PUIAS Linux

Code:
Introduction
This project was started long before CentOS or other projects were available. Even if you do not install the core distribution, the Addons, Computational and Unsupported repositories may be of use to you. The Addons repository contains additional packages not included in a stock Red Hat distribution. The Computational repository also includes additional packages, however, these packages are specific to scientific computing. The Unsupported repository is a place where one time packages are put, they are unsupported and may change frequently.

Be back in touch soon, I have some testing to do...
