Indeed, but it's still the best for athlons. The biggest difference is the 512 MB/sec PCI bus instead of a 256 MB/sec. They are also cheaper often available without on board video like most of the MP chipset boards. via, ali and sis haven't come up with anything newer? that's kind of hard to believe! None of those companies got into the dual athlon market, they all came out with numerous uniprocessor chipsets. This is changing with opteron, at least nvidia plans to come out with a SMP chipset. i'd like to run dual MP 2800's with barton core. udma 133 or higher. built-in usb2.0 would be nice (although i understand that usb2 cards are dirt cheap). There were usb2 bugs in the earlier MPX boards, most vendors threw in a free pci card for usb-2.0. I believe this was fixed. IMO I wouldn't invest a whole lot on such systems. They tend to be rather heat sensitive, definitely plan on keeping the environment cool, and having lots of fans. Performance is often limited by the shared memory bus. any mobo recommendations? I have 24 tyan MP boards, and 8 MPX boards and they all work quite well. Keep in mind opteron-240s are $190, and the opteron dual motherboards start at $240 ish. The opterons feature (compared to the MP's) Much better perf per watt Double the registers (int, fp, and vector) SSE2 (athlon doesn't have it) Double the register size (larger pointers and ints) On board memory controller (lower latency) Per CPU memory interface (not shared) Dramatically better performance per MHz. Less total power. Few extra security features PCI-X (1GB/sec) Often sata is included in the motherboards. -- Bill Broadley Information Architect Computational Science and Engineering UC Davis ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

USB and serial (was Re: [vox-tech] lbncurses.so.4 issue)
Unfortunately, the box on mine proudly proclaims that my model is USB only. And there is indeed no serial port on the back. When Jennifer first found it on Belkin's website, I examined it and saw that the copy said it was compatible with Linux. And, indeed, there is a Linux version of the software on the CD that came with the UPS. However, when I looked at the product description again on Belkin's website, I couldn't find anything saying it was Linux friendly. I feel like I've been had. Assuming the software wants to talk to a serial port, and the device only has a USB port, is there a way to make them talk to each other? On Tue, 2004-02-03 at 00:55, Samuel N.

[vox-tech] latex: flowing around text
hi all,
occasionally i'll find a google groups link that's so useful that it'll
come up again and again in my searches. i happen to know that we have a
few more latex users here than we did a couple of years ago, so i'm
posting this in hopes that it'll be as useful to other people as it has
been for me. this is a truly wonderful post:
http://www.google.com/groups?q=flow+around+text+group:comp.text.texhl=enlr=ie=UTF-8oe=UTF-8selm=3unt1u%24i3r%40krant.cs.ruu.nlrnum=1
the guy compares and contrasts different ways of getting text to flow
around floats.
the reason why this is so noteworthy is:
1. the topic is not mentioned in the lamport book.
2. the topic is covered in the companion book, but the information is so
old that it's wrong. for example, my hat is off to anybody who
actually gets parpic to work well...
fwiw, i've found that picins is the best solution for wrapping text
around a float. here is an example of picins in use:
\usepackage{epic,eepic,picins}
\parpic{%
\begin{picture}(150,50)
\put(5,10){\vector(2,3){20}}
\put(5,25){$\vec{A}$}
\put(28,20){$+$}
%
\put(55,13){\vector(-1,2){10}}
\put(54,23){$\vec{B}$}
%
\put(75,20){$=$}
%
\put(100,0){\vector(2,3){20}}
\put(113,8){$\vec{A}$}
\put(121,30){\vector(-1,2){10}}
\put(118,38){$\vec{B}$}
\put(98,0){\vector(1,4){12}}
\put(93,22){$\vec{C}$}
\end{picture}%
}%
%
The rule for adding vectors in geometric notation is: Put the two
vectors `heel to toe', and then draw an arrow that goes from the heel of
the first vector to the toe of the second vector. In the diagram to the
left, when you add $\vec{A}$ and $\vec{B}$, you get $\vec{C}$.
works very well. a couple of notes:
1. the % characters are comment characters. they help avoid
extraneous newlines.
2. don't use epic without using eepic. vectors/lines that aren't
horizontal, vertical or 45 degrees come out MUCH better drawn.
