I just wanted to second Martin's words.
We originally had Itanium because a lab or two had some Itanium clusters, but 
those went away for whatever reason, and we eventually dropped support due to 
nobody wanting it.

If you want numbers they are here

https://www.scientificlinux.org/about/stats/arch.html

Although the number of downloads is somewhere between 12-40, when we actually 
looked through the numbers, those were usually mirror sites.

I believe someone said CentOS was an option.  This is true for CentOS 4, but I 
don't see a release yet for CentOS 5.
