[K12OSN] K12LTSP on dual opterons?

[Spencer, John]

I have opteron (x86_64) systems with 2x CPUs running the RHWS3.0 SMP kernel.  I had initial stability issues that were solved by applying the latest x86_64 errata, below is the output of 'cat /proc/version':

cat /proc/version
Linux version 2.4.21-4.0.1.ELsmp (bhcompile at thor.perf.redhat.com) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-20)) #1 SMP Thu Oct 23 01:18:32 EDT 2003

All my opteron's are using the 246 chipset and have excellent performance, 32-bit performance is comparable, and sometimes better than, the latest Xeon chipset.  And 64-bit performance has been been better than the latest Itanium2 systems that I have for everything except floating point intensive processes.  I have at least 1 system maxed out with 16GB of RAM that performs extremely well, no obvious latency due to the large memory configuration.

Below is a link reporting on a fairly controlled benchmark comparison of opteron vs. xeon for 32-bit performance.

I know a few people here have deployed dual AMD Opteron servers, but I don't remember seeing any comments on their performance.

One of my schools is looking at buying one, but they would really like to know how well it works before they drop the cash.

If you using an Opteron server, would you be so kind as to post your experiences? (speed, stability, etc)
