Linux 3.0-ARCH #1 SMP PREEMPT Tue Aug 30 08:53:25 CEST 2011 x86_64 AMD Opteron(tm) Processor 6128 AuthenticAMD GNU/LinuxSymptoms:
The computer initiates reboots without warning every 2-3 days, and seems to reboot every time after running computationally intensive programs (that uses all 32 cores and most of the RAM).
Error message:
Essentially none.
/var/log/errors.log does not contain any logging around the time of the reboot.
/var/log/everything.log also does not contain any logging around the time of the reboot.
/var/log/crond.log

Nov 11 16:49:01 mdt3 crond[1473]: FILE /var/spool/cron/root USER root PID 10861 job sys-hourly
/var/log/user.log is empty, confirming that no users initiated the reboot.
Other signs:
CPU temperatures appear normal (BIOS indicates "low"). conky indicates 36~40. (Temperature is likely closer to 60 when running computationally intensive programs.)
However, I doubt CPU overheating is the cause, since the motherboard would BEEEEEEEP, which is hard to ignore.
Summary:
Workstation with 4 CPU sockets (Opertion 6100, which has 8 cores each), and 96 GB of *unregistered* ECC RAM.
I don't know whether the problems are Archlinux-specific, since I do not use any other OS on this machine. My other Archlinux machines do not experience the same problem.
No error messages appear in system logging.
Only I am logged in. No logging of a user-initiated reboot.
I suspect that since the RAM is unregistered (though has ECC), perhaps some inconsistency occurred in the RAM...
Any suggestions would be helpful.

Re: Random reboots on AMD Operton 6100 system
Is this a new setup?
Hmm... try other OS (you can boot some livecd/flashdrive) and run it the same way and look for reboots, If it fail again on other distribution/other kernel/windows server you should look more into hardware/memory compatibility/bios configuration than OS

Re: Random reboots on AMD Operton 6100 system
This sounds hardware level. Can you access the IPMI logs (apparently is integrated on that systemboard) and see if they shed any light?

Re: Random reboots on AMD Operton 6100 system
Try running "mprime" for a couple of hours and check that the results are valid.
Philosophy is looking for a black cat in a dark room. Metaphysics is looking for a black cat in a dark room that isn't there. Religion is looking for a black cat in a dark room that isn't there and shouting "I found it!". Science is looking for a black cat in a dark room with a flashlight.

Re: Random reboots on AMD Operton 6100 system
You could try running memtest or something like to check all ram modules are ok, although I don't know if that could prompt a reboot. My other guess is it is a problem with the PSU, either not powerful enough or it is not working properly.
