21) Message boards : Cafe SETI : SETI Certificate Frame? (Message 532302)
Posted 2720 days ago by Profile [STS]LoBProject donor
I have sent a note to Eric Korpela about selling them again in the Seti store.


Thank you. While you're at it, could you also ask him to deliver to Europe? :D If I recall correctly, they were only delivered to US & Canada back in the years.

Anyway, thanks again for your help!

I remember years ago there was an offer for a SETI@home certificate frame here on this website. When bought, a part of the money would directly go to the SETI@home project...

Aren't these frames available anymore? Anyone who wants to sell his one? ;)
23) Message boards : Politics : Fun with Global Warming - Part Deux! (Message 531296)

Hi,

I'm not visiting this message boards on a regular basis, so I've noticed this thread just tonight. It's a very interesting thread, and I've read half of it allready (while ignoring the flame wars ;)).
I've found some nice advice, e.g. the LED light bulbs - I will consider using them - I've been using "conventional" energy saving bulbs 'till now. Any experience with the "warmth" of the light they emit? Does it "look" like light emitted from normal bulbs?

A phrase, which is coming to the point of this topic (and which I like) says: "Think globally, act locally!"

So, I'd like to see the discussion got into the direction whether or not using distributed computing like we do is good/appropriate, and to what extent.
In my opinion we should for example NOT dedicate computers to SETI@home (please don't feel offended, I have done so myself in the very early days of SETI@home, I just won't do it again), so in order to achieve this, one could think about a restriction in the BOINC system which rejects results from clients running 24h a day. Or an automatically shutting down BOINC client after some hours.
That way people wouldn't have BOINC as a reason to leave their computers running.

What do you think?

No matter what - keep discussing in a constructive manner, and do whatever you can - it's for the good of all of us - and our children!

BTW: I'm using a power meter on my PC, and I've compared power consumption with BOINC enabled to BOINC disabled: It uses 20W more (on my laptop cpu Intel Core Duo T2600)
24) Message boards : Number crunching : How much improvement do optimized clients give? (Message 529697)
Posted 2725 days ago by Profile [STS]LoBProject donor
I think I would remember my former RAC and watch it rise slowly to the terminal value, which takes several weeks. One could subtract total outputs of each machine and average the daily differences but then the pending credit and "Ready to Reports" would would cause those values to vary. Hours on per day is a factor, too.


Hehe, good idea, unless your RAC was nearly 0, and you were starting right away with the optimized client. Like I did ;)

Thanks for all the answers, and keep up the good work! :)

If optimization improves crunch times so much, why not detect the client's cpu and send it optimized binaries right from the start?

This project doesn’t have the resources to develop optimized apps; there are only a handful of staff and grad-student programmers, who are already busy developing & debugging apps for the Beta project.


Yeah, I guessed that. But then again - there are obviously working apps which are optimized. Why not check and then integrate those?

One could look at the crunch times of the default cruncher and compare them to the times of the optimized cruncher. It is very important to compare several units of each credit range; for example, 12-, 18-, 25-30-, 45-50- and 60-65-credit units. Usually the angle range (how far the scope drifts through the stars during the unit's 107-second collection time) determines the number of credits assigned to each unit.


OK, thanks!
But to do this, I have to be able to switch back to the default app. How can I do this?

But I expect the next credits uproar, because this will lead to less credits per time in comparsion to the optimized ones yet, as everything coming from the project direct is just standard and has to recieve the same credits like other projects.


Good point, but on the other hand the most important thing is science ;)
And moreover it's even more unfair now, as only people who know of the optimized binaries can benefit from them...

Here is a link to our class page stat in case you haven't found it and are interested.

Thanks. I still know that one :D

Hello :)
Thanks for the answer, class mate ;)


*edit* One more question: If optimization improves crunch times so much, why not detect the client's cpu and send it optimized binaries right from the start?

Hello!

I've just installed these optimized binaries for my Core Duo processor. How much of an improvement in terms of crunch times will they give me?

Posted 2883 days ago by Profile [STS]LoBProject donor
First of all: Sorry for posting this allthough it had allready been discussed. Didn't know that.

Regarding coding effort and too few manpower: SETI@home has a huge userbase, each of these users have their talents, their should accidently be some who could (and perhaps would) code something like that in their freetime. I mean, people also compile own optimised versions etc...
33) Message boards : Number crunching : Folding@Home using GPUs (Message 430313)
Posted 2884 days ago by Profile [STS]LoBProject donor
http://folding.stanford.edu/FAQ-ATI.html

In short, Folding@home uses ATI's X1900 GPUs to better fold proteins. (Increase of calculations by 20 or 30 times...)
Would that technique be able to help SETI@home as well, or ar the calculations of a completely different nature?

Then you can print it out through http://setiathome.berkeley.edu/cert_print.php


No, these are different certificates (not the ones that I want).

_PLEASE_ let me adjust my account before the website goes offline :(

Posted 3178 days ago by Profile [STS]LoBProject donor
Hi,

although this concerns the SETIclassic website I post it here in hope for quick help, as the classic project will be down in a day or two :-(

I recently reached the 5000 milestone (although it has had to be due to that bug, I shouldn't have hit this mark tonight already...), and thus I wanted to print out the 5000 certificate. Before printing certificates, I always change my profiles nickname to my realname, unfortunately, this doesn't work anymore. The CGI Script just answers:

"CGI error

Command not recognized"

Any help is appreciated, although the situation during the recent weeks doesn't make me very hopeful...

Have a look at this article from a German PC magazine: http://www.pcwelt.de/news/hardware/109635/index.html
Use babelfish to translate, or just have a look at the diagrams on the subpages...

Posted 3705 days ago by Profile [STS]LoBProject donor
Transfers only occur while uploading results or downloading workunits, that seems to be normal.
But I do have the smae problem with workunits not getting accounted for :/ I surely hope they don't get lost completely...
