That's where I'm going, and likely dual. Serial-ATA too. Thats another thread though. Anxiously awaiting seti performance on that bugger.

I am saving my pennies, even got a TA job here at school to make some more cash by teaching freshmen. 
I would like a dual, but I probably can't afford it, oh well, 1 64bit processor will have to do. Oh yea, and Gentoo will support it as soon as I order one right?

I think the Ars Technica team is cheating... http://setiathome.ssl.berkeley.edu/stats/team/team_14240.html
but we can still top them, you know, with the fastest linux distro out there
I like my Athlon 1600+, but I want an opteron.... :drool:

I currently hold the dubious honor of having the longest average time per work unit on the team! Dunno how much longer I'll keep it though...my combined throughput on the two machines I have is about 3.5 hours per unit now. Hehe the first machine I ran Seti on took like 50 hours a unit (!) |

I'm in, with a Pentium 2 233 ( ), an Athlon XP 1600+, and (when I'm not booted into Windows) my dual P3 1.0 GHz box. I just hope I have adequate cooling.

Argh, the init script doesn't launch >1 process on dual-processor machines. So, one of my CPUs was sitting idle.
Not to fear, though. Behold, the newly souped-up, multi-processor-aware init script. (It ought to work on single-CPU machines as well; it deduces processor count from /proc/cpuinfo and doesn't do anything if the CPU count is 1.)
/etc/init.d/setiathome:
| Code: | #!/sbin/runscript
cpus=`grep -c processor /proc/cpuinfo`
checkconfig() {
if [ ! -e ${SETIATHOME_DIR} ]
then
einfo "Creating ${SETIATHOME_DIR}"
mkdir ${SETIATHOME_DIR}
fi
if [ ! -e ${SETIATHOME_DIR}/user_info.sah ]
then
einfo "Setting up SETI@home for the first time"
cd ${SETIATHOME_DIR}
./setiathome -login
fi
if [ $cpus != '1' ]; then
cd ${SETIATHOME_DIR}
for cpu in `seq 2 $cpus`; do
if [ ! -e ${SETIATHOME_DIR}/cpu${cpu} ]; then
mkdir ${SETIATHOME_DIR}/cpu${cpu}
cp ${SETIATHOME_DIR}/* ${SETIATHOME_DIR}/cpu${cpu} > /dev/null
rm ${SETIATHOME_DIR}/cpu${cpu}/*.sah > /dev/null
cp ${SETIATHOME_DIR}/user_info.sah ${SETIATHOME_DIR}/cpu${cpu}
fi
done
fi
}
start() {
checkconfig
if [ $cpus = '1' ]; then
ebegin "Starting SETI@home"
else
ebegin "Starting SETI@home ($cpus processors)"
fi
for cpu in `seq 1 $cpus`; do
cd ${SETIATHOME_DIR}
if [ $cpu != '1' ]; then
cd cpu${cpu}
fi
./setiathome ${SETIATHOME_OPTIONS} >&/dev/null&
done
eend $?
}
stop() {
ebegin "Stopping SETI@home"
killall setiathome
eend $?
} |
If you have a >1 CPU machine, just replace the init script with this, and to a /etc/init.d/setiathome stop, /etc/init.d/setiathome start. (That's because checkconfig isn't called on restart, just on stop/start. It's silly.) It will make a copy of your SETI directory (into /opt/setiathome/cpu#), delete the work files in the new copy, and launch an instance in that new directory. Very nice.
Have fun. (Maybe I should submit this to the bug tracker...)
Edit: bug 7483 filed.

Oh, come on. My user page currently shows that I've been a member for 330 hours with ~1900 CPU hours put in. That's only 5.7 processors on average.
Doesn't everyone have 5.7 unused processors at their disposal?

What's silly is that it was running on my dual-CPU box for ~12 hours, then I added another one (about 85% of the CPU), then another one a few minutes later, then another one 24 hours later...
Now I think I'm up to nine or so. But I'm not sure.

I joined the group! I've been a seti user for a long time. I was originally under 'kevin' but I changed my nickname to match my gentoo forum nickname.
I've been a seti contributor for a long time. I used to have about 15 computers running it, but now I'm down to just my 90 MHz pentium firewall and 700 MHz athlon thunderbird workstation. I might also add the 1.7GHz p4 at work, but I'm not the only one using it right now. |

Woohoo! Someone from Armenia has joined the team. I was hoping to see the non-US users grow.

Actually that would be me, and I'm really from Denmark but I kinda put the wrong number in the profile - it should be corrected in the next update. |

Yeah... Denmark is nice, sadly I don't see many danish Linux users, let alone Gentoo users.. |

I've joined too, although I don't have many results since I only started seti this week, and I have a slow PC.
I have a confession to make. I am not a Gentoo user, I run SuSE  . I will change to Gentoo as soon as Deutsche Telekom can get my ADSL connection working. Hope you don't mind.
Has anybody emailed the members of the other Gentoo seti groups to ask them to switch over?

I just got the following e-mail:
| Quote: | Dear delta407,
Congratulations on recently completing your 250th SETI@home workunit. Through your support, SETI@home has grown to become the largest distributed computation on Earth. We at SETI@home greatly appreciate the 0.28 years of computer time you have donated to the project, and hope that you will continue your support. |
Member for 420 hours.

hehe Congrats
If I continue at my average time per unit, I should hit 250 in 888 hours... |

I am clearly in a different (lower) league to the rest of you, since my PC has only managed 2 work units in 69 hr CPU time.
However, I have also completed more work units than 42.136% of SETI users, which means that a lot of people register, but never give any CPU time to seti@home. Why do they bother?

Maybe alot give up after 1 result. I had some problems for a while when the GUI part only ran at 800x600 resolution. This could have been part of the problem.

I think like alot of people, they hear about seti@home then go the page to download it and make a userid. When it comes down to running it continuously, they shutter a bit. They probably put in a day or two of effort, but thats it.
I used to run it continously on about 8 machines back about 3 years ago. (all 500mhz and up) I just started running it now, since I was reminded of it I just need to go to the site and figure out how to join a group. |
