Seti Comeback?

I have been involved in the Eccp project for a while because it offers great ability to manage larger numbers of computers without an internet connection.

I'm beginning to get bored with it now and want to start doing seti again.... but all of my computers have no internet connection. I want to be able to have them cracking 24/7 but want to harvest results say once a week or every 5 days or so.... I do have a cd-rw on the computer that I can access the internet from..... what do i do to get my offline fleet cracking?

My fleet:

1 AXP 1700+ OC'ed to 1800+
1 1.4GHz Athlon OC'ed to 1550ish
1 1.33GHz Athlon OC'ed to 1503
3 1.2 Durons
 
Which one has internet access?

I'm assumming you do not have these computers on a LAN. If you did there would be no problem ... right? 😉

Do you have a CD-RW on each computer?
Do you have a portable ZIP Drive or CD-RW?

If you set this up to do a "sneaker-net" you are going to need some sort of media to move the stuff back and forth to the internet accessible machine. A floppy is just too small. If you don't have anything already in place to handle this you might want to get a portable ZIP or CD-RW.

If you can solve the data transfer problem it would be the simpliest to just move the entire SETI folder intact from each of the non-internet machines to the machine that has internet access. You would have to turn off SETI on the internet accessible machine to accomplish this ... I think. At least that is the way I would handle it. Start up the transferred SETI and hit TRANSMIT (I'm assumming SetiDriver is being used here). Once it has finished uploading and downloading ... shut down SETI and copy it back to your portable media. When you return to the non-internet accessible machines I would completely delete the old version of SETI and then copy/paste the entire folder from the portable media.

This is how I would handle it but I'm sure others would do it differently. I've seen this brought up many times in the past and there are other more subtle solutions but what I have described is sort of a brute force KISS system. 😉
 
Do you have the computers networked?

If so, I would set up SetiQueue on the computer with Internet access and then point the other computers to upload and download their WUs from the SetiQ machine. You can manually connect to Berkeley using SetiQ so you don't have to worry about a permanent Internet connection.

This would be a lot easier than sneakernet or trying to copy all the files back and forth via CD-RW.

EDIT: I see Smokeball already mentioned the networked issue. I should read follow-up posts before replying!
 
I just move the work units from machine to machine myself.Saves time. On the machine with the internet connection up your cache size to however many completed work units you have then exit seti Rename the completed workunits so they match the the unfilled cache folders and cut and paste the completed ones to your seti folder and overwrite the unfilled folders then restart seti and tranmit the results and they will upload results and download new ones. Then exit seti and cut and paste the new ones back to your zip or whatever you are using and move them to the seti folder on the other machine. Restart seti on both machines.
 
I suppose that a portable USB CD-RW would work best..... as none of these computers are networked.

Anyone got a cheap/spare USB CD RW drive

(EDIT: Actually, I'll just hook up my old plextor 12x10x32a and reboot the machines..... I'll test it on one computer, and if it goes well, I'll progressively add more)

Any idea how many WU the best one the 1550 athlon would do in 5 days? (.417 AR)

 
I've got a few machines that are right in that range.

Smoke3 3:18 7 WUs @ day
Scubado 3:14 7 WUs @ day
Smoke8 3:31 6.7 WUs @ day
 
Well to give you a rough idea my Athlon XP1500 @ 10.5x149=1565 with DDR RAM @ CAS 2 does 417 WU's in about 3hrs20 mins on Win2k ,with Win98se its about 3hrs 30mins

Oh yeah ,& Welcome back to The search 😀
 
if you are willing to spend a little bit of money... you should get a USB hard drive 😛

you can get enclosures that you can put normal hard drives into...

at my work (I am not trying to pimp the company I work for, so i'll only send you the url if you ask for it 😛) we have for about $45 an enclosure you can put laptop hard drives into, and for about $60 one you can put normal hard drives into.... you should get something like those and a hdd 😛
 
What Smokeball said in his first thread, i also feel this is the best method, and also the one i personally would use.

Just remember to zip up the directory if using CD-RW, as otherwise all the file attributes will be read only and will make your life a bit of a pain 😉

My Athlon 1.0@1.467 (147FSB) does a WU in about 4:45-5:00, so that's about 5 a day per Athlon, the AXP will get about 8 a day, the Durons i reckon about 6 a day each (just guessing most here!)

So, i would store about 60 on each one to last about a week, then it doesn't matter if you have more than you need, but it's a bad thing to have it run out! 🙂

So, i reckon you'll be getting about 35 WUs per day from those computers, should move you up the ranks quite nicely! 🙂

The Morgon Durons do considerably better in SETI than the earlier ones ,my Duron 1.2@1.31GHz(145HZ FSB) is doing 4hrs35min for an av AR WU 😀 ,so I'm beating your 1.467 Tbird!😛😉 hehe.
That's with PC133 RAM btw
