Hello Seti Team

I have been a low key member for many years with limited computer resources.

I have noticed with the advent of Astropulse, that the tasks I receive take longer to complete.

For instance, yesterday I received a task that will take approximately 250 hours to complete, and I have been given a reporting deadline of 29 days.

To achieve this I will need to keep my computer running and idle for over 10 hours per day for the time to complete deadline.

I am sorry this is just not possible for someone like me, and I certainly cannot afford a new faster computer. Sorry about that, but I still want to contribute somehow.

Please can you relax the reporting deadlines.

Regards

Peter Green

You are not the first person to be concerned with astropulse. Please read the FAQ's on the Numbers crunching forum. THe benefit of astropulse is it is a very large WU with very large credit. AP gives you a better bang for the buck since you wind up receiving slightly more credit for the time it ran. You already know the drawback. One thing that will help you is to install an Optimized application which will decrease your crunching times dramatically and is also talked about ad litem on the numbers crunching forum . As you may have noticed there is an outage of Multibeam(small WU's) which is intermittent at best.

If you really dont want AP WU's then head to your account page/seti preferences and unclick Astropulse astropulse v5 and run other projects.

I am in the same position: I have been crunching units since 1999 so you can guess about how fast my computer isn't. I received a work unit today that will take 1604 hours to complete and even leaving my computer on 24 hours I won't come anywhere close to making the deadline.

What gives....you don't need me anymore?

As mentioned above, you can disable AstroPulse tasks in your SETI@home preferences.

You should set

Run only the selected applications
SETI@home Enhanced: yes
Astropulse: no
Astropulse v5: no
If no work for selected applications is available, accept work from other applications? no

After changing your preferences, you should abort and report the already downloaded AstroPulse tasks.

Gundolf

Hi Guys/Gals,

I joined SETI@home newly, it says i need 360 hrs to complete the project and deadline is another 15 days. I am using Astropulse5. What do i do?

I also had a few basic question.
1)What are these credits for? I joined SETI without wanting to gain anything :)

2)What happens if the project's deadline is done and work not completed? Are the computations my PC did a waste?!?!?

3)Do i need internet connection to upload my PCs work? Can i upload it in pieces or should it always be done in one shot?

Welcome to distributed computing with SETI and to the forum.

I joined SETI@home newly, it says i need 360 hrs to complete the project and deadline is another 15 days. I am using Astropulse5. What do i do?

I think you mixed something up. 360 hours are 15 days, but the deadline (May 9) is 26 days away. So there should be no problem if you can let your PC run 24/7.

I also had a few basic questions.
1)What are these credits for? I joined SETI without wanting to gain anything :)

You won't. They are only a means to brag with :-)

2)What happens if the project's deadline is done and work not completed? Are the computations my PC did a waste?!?!?

That depends. If you miss the deadline, a new copy of the task is sent out. If you return your task before that new copy is returned, you'll get the credits if your result is correct. The new copy will get credits too.

If the WorkUnit (WU) is validated before you return your result, you'll have wasted your CPU cycles.

3)Do i need internet connection to upload my PCs work? Can i upload it in pieces or should it always be done in one shot?

Yes. No, it can only be uploaded in one piece. You won't have anything to upload before the computation is finished.

Gruß,
Gundolf

Ditto here, 529 hours to go, very slow progress, many, many hours trying to get the linux CLI client to run. Oh yeah, the 529 hours to go was incrementing UPWARD, not down. It won't Horrible documentation (like...none) finally installed X just to see if that would work, it seems to, but I don't want to run X. The old Linux client was easy to setup, it had documentation, and it simply ran. I too feel as though my processing isn't wanted. I have three servers that have capacity to run this, and before the client became this boinc crap I was in a high percentile of Seti@Home. What Gives? Why no documentation? That's insane!

For me a simple "How-To" for the Linux CLI version would be great. But this method of turning you loose with the software and you're on your own makes no sense. And I don't do this online chat crap or Skype. Overkill, just need a document with a how-to.

http://boinc.berkeley.edu/download.php

Shows: Help
Then you just go User manual
And for you: Install BOINC on Linux.

What no documentation? As for running 529 hours, that's Astropulse. Do a search, really, that's the best way to get information. Unless you have no time, for who does these days, but then really: why try new software?

Hi mate i've been part of seti for 10yrs i have upgraded the computers 5 times at least why just to keep up with seti thought i finally had a fast machine then came astropulse so i had to upgrade again to a core 2 proccer and a nvida seriers 8 vidoe to get the cuda proccesor (serers 8-9 has cuda) Still takes approx 70-80 hrs for Astropulse and 3 hrs for seti so bacically unless you have a p4 at about 2 gig don't do Astropulse it will take to long do a differant progect like Einstein thay take about 8 hrs on a 2 gig machine . If you realy wish to be part of Bionic (seti) i'm afrad you will need a good computer . 10 yrs ago a p1 used to take 38hrs just for seti could never have done Astropluse so dont feel to bad . I'm homeless and unemployed and have been able to build all but the last computer by getting parts that have been trown out nowdays you can find good p4 and build a good enough machine to do both seti and Astropluse i suggest you keep your eyes open and grab anything that looks decent and it won't be long before you are a seti nut like the rest of us

So the delayed task will still get completed? & the bit of the copy you began will be the only CPU cycles you wasted?

If the WorkUnit (WU) is validated before you return your result, you'll have wasted your CPU cycles.


Which WorkUnit (WU) are we talking about here, the delayed one or the copy?

The late task will be completed if it isn't aborted.

I don't get that.

I'll rephrase: If the new copy (sent to another computer) is reported and validated before the result that didn't meet the deadline is returned, the late result won't get credit.

Hi, it's my first post!

Just want to say this is my first successfully completed Astropulse unit.

I'm sorry man, I can't feel bad about you after reading the specs on the machine you're crunching on - somewhere in the US (presumably). Think about how much electricity you're wasting using that thing (dinosaur). Think about the money you'd save by upgrading - just on electricity alone. I could match your decade's worth of work in a few weeks, maybe less. For a few hundred bucks you could too.

Stop crunching for 6 months and use the money you save on that electricity (you should be able to tell - even if your PC isn't running much more than 200 watts or so going full tilt.)

Then go cheap tri or quad core..toss in a simple GPU, mobo, ram - and for safety - I'd say it's time for a new PSU too (I've seen a fire among other bad things with old PSU's_.. Your PC, if you've never replaced that is a serious fire hazard.

Turn your disappointed frown upside down bro!! Come into the 21st century!

Plus, not for nothing - but there's a small bird choking on smog somewhere because of your insistence on using that old thing.

Please recycle, don't throw away. Do not donate that thing either, as the carbon footprint of any recipient organization would not be benefiting.

Replace "carbon footprint" above with "money saved in electricity" if you think it's politically less offensive and makes you feel better inside.

If the computer is still getting the primary job done, there is really no reason to upgrade. When the machine stops being capable of doing its primary task either due to failure, or because a newer version of the software requires more hardware, then it is time to upgrade. Old equipment is still welcome, and we have people that are still running Pentium 90s.
