enterprise tools (in particular the Cadence/Synopsys tools?)
\_ Probably CentOS b/c it is RHEL recompiled from SRPMS.
\_ I didn't like CentOS 4.2 very much. (64-bit). It's possible
it was misinstalled, but I found it lacking in polish. It was
hard to compile things for it, things wouldn't work... --PM

| 2006/3/2-5 [Computer/HW/CPU] UID:42078 Activity:moderate | 3/2 How is an Opteron different from an Athlon64?
\_ Most Opterons require registered DIMM (940pin) and most
have 3 HT links. 1xx series only have 1 usable one, though.
There're some 939pin Opterons, which are basically identical
to Athlon 64. All Athlon 64s have 1 HT link only and use
unbuffered DIMMs. Internally, they're identical other than

even close to be used as a desktop OS. They've kept telling me that
since it uses Gnome UI, it has the same usability as Linux. How
do I counter that? So far, I can say:
1. Linux has a lot more working device drivers
2. Linux has a lot more consumer-oriented, multi-media applications

| 2005/6/22-23 [Computer/HW/CPU] UID:38244 Activity:moderate | 6/22 I'm doing some performance tuing of a multithreaded application on a
dual-Xeon with hyperthreading. Windows reports 4 cores and counts
1 core @ 100% as 25% CPU usage. I realize this is a fuzzy question,
but what's a reasonable real-world limit for CPU usage in this
situation, since there aren't really 4 cores? This app has a mix of
MMX computation, unaccelerated floating-point math, bus I/O, and a

| 2005/2/17 [Computer/Companies/Apple, Computer/HW/Memory] UID:36223 Activity:nil | 2/17 I need to buy a computer for photo-processing. Currently, on a 3 GHz
P4, it takes Photoshop ~1min. to open up a 5-6MB raw file, and even
longer to do any processing. Are any PC-clones comparable to Apple's
Power Mac's in terms of photo-processing power? A Dual PowerMac1.8
w/1GB RAM, and 20" screen is $3300. Top-of-line PC's are much cheaper.
Suggestions? Advice? TIA.

maybe you should think again: http://csua.org/u/8x7
\_ Erm, maybe I'm missing something, but that page argues that
if someone can gain root access and flash the system with
malicious microcode, they can in the future gain full access
through mere userspace privilege. True, but wouldn't that apply

bit linux kernel or a 64 bit linux kernel in RH 3.0 EL? tia.

going to switch socket types in Q2 2k4 and gave up the
idea. We have a couple of dual opteron boxes at work (newisys)
they are very nice. No problems with Linux (SuSE Enterprise

| 2003/7/31 [Computer/HW/CPU] UID:29197 Activity:high | 7/31 I just bought AMD2500+ (based on 1800Mhz) with FSB of 333Mhz and
installed it on a MB that supports up to AMD3200. When I boot up the
computer however, it says that I have AMD 1100Mhz. I tried playing
with the BIOS, changing the FSB speed and all from 100Mhz to 200Mhz
but the boot screen still says that I have AMD 1100Mhz. What is
going on?

cool toys. Instead of buying a beefy server (like say, a massive server
with 20 386DX processors), buy a few cheap machines (like the ones
mentioned below) that have good disks and work on failover / load
balancing. A netscaler or other piece of hardware is complete overkill,
but maybe hacking an OpenBSD box could do the trick. The idea is that
