Most processing power/Watt

[~misfit~]

Note that the Tualatin P3 (version with only 256K L2) does
better. Difference is FSB & memory speed... Multiplier as
mentioned on that page.

Ok. It's nothing to do with cache latency?

But, CuM uses more power, and Tui can clock higher. Tui on
133MHz FSB/Mem would be good if particular specimen doesn't
require extreme Vcore increase to get there, which it probably
wouldn't since resulting speed is only 1.33GHz.
True.


Via 693 was slow, but Via 694 with good bios may outperform a
BX... they're close though.

Mine's a VT8601T Apollo PLE133T, (according to AIDA32) are they any good?

Keep in mind that the motherboard, memory, drive, are all
overheads that may not remain at a fixed constant but still are a
large overhead. If you have a CPU that's 30% faster but uses 40%
more power, you're probably still coming out ahead by using it.

Good points, thanks.

I don't know how the cache latency compares between the
Coppermine and Tualatin but I was under the impression that
difference between the Tualatin P3 w/256K L2 and the Tualatin
Celeron was only the FSB speed set by default (and the multipler
they used to attain marketed speed at that FSB rate).

PLE should have integrated video. That's a major hit on
available memory throughput, less so the more you decrease
resolution, bit depth, refresh rate. It that case it could be a
significant penalty with any CPU using 100MHz FSB & Mem or lower.
I couldn't guess at a percentage though. If I had a choice of
what to put in a SETI box it'd probalby be something like an AGP
ATI Rage Pro Turbo/XL, since they are very low power consumers,
low heat... don't even need a heatsink on 'em. Plus by modern
standards they're just about useless for anything more (GPU)
demanding than watching a DVD.

On the other hand, the integrated video might result in energy
savings over many video cards, it could take a lot of
experimentaton to determine a work units to energy efficiency, as
it's effected by several variables.

Then there's a whole different option, giving a PC to your
neighbor for free providing s/he keeps it on and crunching
SETI... at least power is then free for you.

Ok, I seem to remember reading somewhere that the cache latency was raised
(?) on the Celly's to deliberately make them slower. We need someone with
both and a utility to test it.

Yep, this board has on-board video, audio and LAN.

I have a couple of 8MB S3 Trio 3D/2X AGP cards spare but this board doesn't
have an AGP slot.

Yep. At least with the new BOINC client you can specify how often it writes
to disk so you can have it power down. However you need a bit of RAM for
that and the power-cycling of the HDD probably isn't good for it.

neighbor for free providing s/he keeps it on and crunching
SETI... at least power is then free for you.

That's virtually how I got this board/CPU/RAM plus the guy is sending me two
more boxes this week, a Celeron 1.2Ghz and a PIII 1Ghz. I met him through a
couple of groups we have in common and he's reducing his SETI farm, or
upgrading it, not sure. Awesome guy, really generous. I was talking about
tweaking my old boxen for SETI and he emailed me and asked if I would like
them, the only condition being that either I run SETI on them or pass them
(or the boxes I replace with them) on to other members of my team to run
SETI on. He's not concerned about his own stats, he doesn't care who's
account they go on as long as they are used for SETI, not necessarily
exclusively or 24/7, (although that would be preferable) just whenever
they're on. As you can imagine I was more than happy with that as a couple
of the machines I'm running are fairly slow, one in particular, a Mendicino
500.

I thought about passing on the other machines to PC-less people with SETI
installed (an an agreement that it stays installed and running) but I don't
have the monitors spare, or the OS licences. Plus they'd need an internet
connection.

Oh, forgot to mention, the Tualatin boards have bulging caps, still running
though. He knows I've replaced caps before, that's part of the reason he's
giving them to me. Damn generous to give me the CPUs, RAM etc as well
though.

I'm leaning towards getting some Slot-T's now though and putting the Tui's
in BX boards.

That is a very generous offer, and I thank you for it. However, I see
you are from The Netherlands and the team I founded is a team for the
readers and posters in the nz.comp newsgroup. I am in New Zealand.

Ah, yeap, I picked up your location, reading through this newsgroup for the
last year... I just feel the internet makes the world so small, our exact
locatiuon is of little importance

That being said, there is no reason why you can't be out first member
from outside NZ if you so wish. Are you still crunching Seti classic
or have you gone over to the new BOINC client yet?

Aha... I was still crunching the block the old fashioned way ;-) I just
installed the 'driver' and 'setispy' stuff to get two instances of Seti
running, utilising my hyperthreading thing to the max... Well, I just
installed the BOINC stuff now, it's trying to connect... Has some problems
with it :-/

Classic team:
http://setiathome.ssl.berkeley.edu/stats/team/team_155750.html

BOINC team:
http://setiweb.ssl.berkeley.edu/team_display.php?teamid=30823

Our members are slowly switching over to BOINC as classic will be
terminated at an undisclosed date not too far into the future. There
are currently problems with the SETI servers (when isn't there?
) so any changes could be difficult currently.

Feel free to join if you so desire. I would welcome your contribution.

Okay, I tried to join them both, glad to be aboard, skipper ;-)

Do you recommend it? I enjoy fantasy but have yet to read it.

Ah, well, it's..... a bit weird ;-) For a Dutch guy the language is
sometimes a bit troublesome; the guy wrote stuff in a language like old
english, hehe.... The book is from the 20's anyway, and, all in all, quite
nice. The main problem is that the language is a bit too rich (he can take
half a page to describe someones clothing) and some events are portrayed
very detailedly, while in some othe cases he chooses to skip 3 months in
time. Nevertheless, it's a nice epic, very romantic, brave heroes and
terrible treacherous villains. All in all, a good reading experience to me
;-) Lord Juss and Brandoch Daha will be in my memories for a while...

Okay, see ya...

Yes, the servers have been down. To the best of my knowledge they are fixed
now, just trying to fill the backlog, lots of people wanting WU's. I have
two PC's with no work at the moment.

Thanks for that. I read a lot of fantasy, I have six books out from the
local library at the moment that I'm racing to finish before I get fines.
. With trilogy's and the like it's hard to get all the volumes at once
from the library. When I do I have to read them quickly.

Cheers, and welcome to the team.

Well, this one here I have returned to it's job crunching classic blocks,
BOINC is not working here... Any ports I need to keep open?

Hahah trilogies, hmm, unfortunately I dont have the time to finish those in
our librarie's loan term

This one is quite cool to read, and one of the earlier, i think. Nice to
compare with the LOTR epic.

Okay, I hope I'll be able to do some useful (crunching) work ;-)

I have two of my machines crunching Classic until I can get some BOINC WUs.
No I don't think there's any ports you have to open.

So I've heard.

I'm sure you will, cheers Thomas,
