Dual-core Opteron Support on RHEL v3 2006-01-22 - By Rik Herrin
Back
Hi,
We were thinking of purchasing a dual-core Opteron
and deploying an application requiring RHEL v3 U2 on
it. However, after reading the following article,
http://www.anandtech.com/printarticle.aspx?i=2447, it
mentions the following:
"The new Dual core Opteron makes our test complete.
While Windows (XP and 2003) recognized and utilized
the cores easily, SUSE SLES 9 Linux was a little more
stubborn. With the original SLES 9 kernel 2.6.5-97,
the dual Opteron would just crash. We applied Service
Pack 1 and the new Opteron would boot and recognize
the two cores, but the second CPU was disabled because
of APIC IRQ problems."
So will RHEL v3 U2 (ES or AS) see the dual Opteron and
use both CPUs? Also, how many CPUs would it support
if it does see the dual Opteron as 2 CPUs? Can I
comfortably install on a machine with 2 x dual
Opterons or 4 x dual Opterons? Thanks for your time.
