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).
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.
PLE should have integrated video.
Yep, this board has on-board video, audio and LAN.
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.
I have a couple of 8MB S3 Trio 3D/2X AGP cards spare but this board doesn't
have an AGP slot.
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.
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.
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.
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.
