Checked my machines, and a P3-700MHz, 512MB Linux machine of mine, for
which I haven't found any optimized binaries, has one queued up,
expected run-time: ~205 hours. Weird, since I don't meet the 1.6GHz
requirement, but we'll see how this turns out.
That is odd indeed. ~205 hours huh?
That's what the Linux utility 'boinc_curses' (a Linux console only clone
of the BOINC Manager) claims/shows.
Just for the hell of it, when I got my
first couple, I checked to see what other PCs they were sent out to and the
others all met the requirements although they were all heaps slower than
mine. My 'average work done' has suffered since I started getting Astropulse
units as they're taking a long time to verify. (None has yet..)
My RAC has more or less doubled on the Q6600 machine after I installed the
AK8 SSSE3.1 binaries. ;) I'm not yet clear on how I have to merg the
app_info.xml files to get boinc to use the 'regular' astropulse client for
ap units, and the optimized stuff for the regular units.
I did that, even partitioned disks in a primary C: for the OS, a D:
for Programs and an E: for data, but as time went on, I noticed I was
running out of space on all of them, so nowadays I stick to a
somewhat larger C: (25GB for XP/Vista32 seems to be fine, Vista64
needs a bit more, so I set that at 50GB), and the rest of the disk as
one big D:
Ok. I have XP Pro on a 5GB partition which it shares with what I class as
'OS-essential" apps such as AV, Acronis, PerfectDisk, PartitionMagic,
Spybot... There's still 1GB free after a year on this install. I don't have
my pagefile in that partition though.
Hmmm, I did that (5GB C:), but that gets small very quickly. That is/was
with swap on C: too, so that then gets moved to D:.
Programmes is 15GB and is nearly full, I might have to increase it a bit
with PartitionMagic. I have a 2GB FAT32 partition for pagefile only, at the
start of a fast disk. The balance of those disks are large data partitions
and the other disks are one big partition also. I find that, as I keep
multiple backups (Acronis True Image) of the boot partition and sometimes
the Programmes partition keeping them small is good. (Although Acronis
truncates the free space anyway so I'm not sure that backups would be *that*
much larger on bigger partitions with the same amount of data.)
I don't make too many images; a re-install is done quick enough, and the
only sure way to get a clean machine again. ;)
Well, I've set my preferences to 5+5 days of work, so all machines are
still crunching on, and aren't even halfway past their cache.
Good move. Mine is 1+1 and I was out of work for a while, then got a couple
units last night, now am out of work again. :-(
I had it set a lot more 'conservative' at first, but after the last big
outages (I think these happened somewhere in 2007), where the servers were
out for days, I just set it all to the maximum, more or less after those
events, when all my machines 'ran dry'. They haven't run dry since then.
Yet anyhow....
I'm waiting on delivery of a 45nm CPU, an E7300 that should arrive any
minute. My E4500 has been running at 3.32GHz for a while now, time for a new
challenge. The E7300 has a 10x multiplier so I'm hoping that it will run on
a 400MHz FSB (1600 in Intel-speak) for 4GHz at sane vcore and temps.
<fingers crossed> It's actually quite a big job as my cooler has a
"bolt-thru" kit fitted which means the mobo has to come out and the case is
quite cramped with all the HDDs and a full-length GFX card, SCSI card, sound
card..... Also, I lapped the E4500 which gave me ~6�C cooler temps so I
might have to fit the E7300 twice. (I don't want to lap it out-of-the-box
until I'm sure it'll at least work!)
Sounds like a nice project. ;) Good luck taking that thing to the limit!
I also ran a 6.3.6 beta client for a while, and one of the most
interesting messages that spat out during startup was the line "No
CUDA devices found". I suppose it would be very neat if I could use
my 8800GTX as a Seti@Home cruncher, but no client is in sight AFAIK.
Darn.
Yeah. There's a client for ATI cards no? (I have nVidia too) I can imagine
that running on both CPU and GPU would bump up the power consumption quite a
bit!
Not that i know. I suppose an 8800GTX running at full-bore would be quite
an energy-slurper. ;) No idea how much Seti@Home tasks it could, in
theory, run. I find some snippets here and there, but no client yet. We'll
see if I can harness the power of the GPU in the future... ;)
Ciao, Patrick.
