Politics and the work we did on Seti@home is less useful than we thought. I was once proud of my efforts toward Seti@home, meager though they were. We gave up too soon.

Sorry, I was in the hospital and couldn't post earlier. I just wanted to say that I'll miss Seti@home. Good luck to everyone, and thanks for letting me help.

May 16th, 1999. Nearly twenty-one years. I've not been the best - too many periods without internet connection and I've never had great computers to work with, but I've never done anything else. I've never really wanted to do anything else.

In the abstract, I understand why the project is ending, but I'm sure I'll be lost for a long time without it.

Thanks for having me.

I've looked and haven't seen this issue, but I tried to print my Certificate for twenty years and the date was wrong on the Modern and Photo certificates - a day early, but correct on the first one. It's not the end of the world, since I just used the other one, but I figured I would let someone know.

The work units haven't "gone for ever", only the copies sent to you as tasks have gone. The work units will be copied again and sent on to someone else.

I wanted to apologize to everyone who was/is waiting for work from me. Suffered a complete hard drive failure and had to wait to order a new hard drive and then restore what I could from it. I'm back up now, but I'm afraid those workunits are gone forever.

Take as long as you need to. You're doing a great job. I keep getting more CUDAs to work on, so even if you can't get it done before the new year, I've got WUs to keep me busy.

The workunits people are receiving are re-sends of timed out workunits from other user's accounts. They are not fresh workunits.


That's all right. I don't need fresh workunits. In today's economy, I know there are people who aren't as well off as I am. Indeed, somehow I've picked up 34 workunits over the last couple of days, including five or so since I checked it a couple hours ago. This doesn't even include the ones I've finished over that time.

I've only got one video card. That's enough work for a week, at least!

I'm not complaining. I know the money hasn't always cooperated, but I've always said that if it ever came down to taking it down for a month to get it running right, I'd always support it. Whether we say it enough - whether _I_ say it enough, you guys are doing good work. Lord knows I would have gone after the servers with an axe by this time if it were up to me.

I've got some work for a couple more days here and then I guess the system will be taking a break for a little while. It probably needs a break though.

I figured this was coming in the debate. I was not surprised. Eleven years on and I find out that my opinion isn't good enough. Sorry I couldn't afford to buy all those fancy computers.

Can you imagine that some folk that really bust their butts to keep stuff running most of their time also have a LIFE at a weekend that enables them to wind down and put up with the other stuff which happens when they are not there?



That's just crazy talk. Heh.

I'm not unbiased, but I give the staff kudos for what they've done and assign only the slightest of blame when things go wrong. Sure, if they stayed there 24/7, things might work smoother, until they snapped and killed everyone for wasting their lives away working for peanuts.

A long time ago, I set my cache abnormally high, like eight days or something. I don't even remember why. I always planned on changing it, but at times like these, I'm happy I didn't. Anyway, I'm still crunching, so I'm good.

This is just as I suspected. We let the machines band together and now they're smarter than us. Our only option is to swear fealty to our new machine overlords and hope we are spared from the coming apocalypse.

On a side note, I almost gave up on CUDA on my first try. I think it might have been growing pains, but it sure as heck slowed my system WAY down. Now, I think I can live with it, but I wasn't so sure before.

You might help your cause if you maintained a small cache of work units, and if you had a back-up project. Since your main interest is SETI, you could even consider SETI Beta as your backup; it does have work at the moment. (These points have been made by others. Often.)

The SETI servers are not down at the moment. (I have managed to snare a few work units during the past 10 hours.) As explained by Matt, they're straining under a heavy load brought about by a convergence of adverse circumstances. They therefore cannot keep up with the demand. As Martin points out, demand is the essential difference between your setup and that of SETI@home.[/quote]


He has a point though. Seems to be the long weekends when these strange problems occur. Of course I can't prove that.. just seems that way.

Anyways, there is no point in complaining about these little outages. The servers will be up when they are up. Some things just take time.

I upgraded 1 of my PCs to a C2Q 6600 from a P4 2.53GHz. Then found out that the splitters were down.. lol.. ran out of cached WUs in less than 2 hours.

Anyways, good luck getting that index copied over. Hopefully you can get those splitters back up for a few hours today so I can download another 4 days worth of WUs.

I was lucky. I ran my system out of work deliberately two days ago to make sure my upgrade to the latest boinc was flawless (prolly unnecessary, but I've had a bad experience once). I'd just manage to get the cache full a day before this came up, so I should be good.

I wonder about the people though who complain the most. It's true, I am nearly religiously against other projects (haven't found one I liked, am not going to join another 'just' to keep busy), but why complain about the project not working flawlessly. It's hard to keep things together on the edge of technology, with a very limited budget, and very limited time. What do you expect? Even the computers on the space station go down once in a while.

Matt, tks for the information,

But in fact, there are U/D load problems !

I have about 2000 WU to report each week ! And this only into 1 hour time due to the Intranet security. I reveive from the RDM 1 hour, once a week , open gateway to Seti. But when Seti is very slow, or offline it became problems ! I want to help the research.
Perhaps is it better to close Seti for a few days or weeks to solve all the problems.
All what it sended during server problems are into " fixing missing results ". But this server is out since the big crash in august.
I have now about 8.000 WU waiting for assimilation !!!
Each WU about 50 credits, it become about 400,000 credits !!!

And of course , when I connect and can receive new WU, they are also calculated. The final result is when i start the U / D load, your server receive much more information than it is capable to proceed. Weare more than 1,000,000 with the same problem !!! Of course when the server receive at the same time so much request, it can not proceed because the overload !!!

It is a snowball effect !!! Only Seti team can solve it. Then DO IT !!!!!
Instead of trying to repair "broken arrows " !



No fix is forever. Even if SETI were taken down for a month, it wouldn't guarantee that there wouldn't be a hardware or software crash later.

I was going to get some programming done today but Dave needed php upgraded on the BOINC server, which was running Fedora Core 6. FC6 didn't have a sufficiently advanced php in its repositories, so this was as good a time as any to yum the system up to Fedora Core 7. This was slow, but worked like a charm.

Except I then realized the trac system (used for BOINC's web based public software development) was toasted due to the upgrade. It took over two hours of hair pulling, scouring log files, removing/reinstalling various software packages, poring through barely informative pages only found in Google's cache.. I don't really understand how what we ultimately did fixed the problem, but we seem to be out of the woods, more or less.

I hate to say it, but trac is written in python, and I've never had any positive experiences with this programming language. Every six months some random python program explodes as it is utterly sensitive to version upgrades, and tracing the problems is impossible as the code is difficult to read and scoured all over the system in vaguely named files. Others keep trying to convince me python is the bee's knees, but I just can't see it. I started out writing raw machine code on my Apple II+, so to me C is the pinnacle of programming languages (not C++). I'll shut up now before I further offend python programmers/developers.

I have often considered myself a young dinosaur because I sometimes wonder if things might not need to be changed just because they can be changed (The latest example might well be Vista, but I digress). Anyway, thanks for the effort, sorry about your hair - the parts you pulled out should grow back eventually, and good luck the next time it breaks.

Post:

You can set a very low resource share for a backup project, i.e. Seti 100:1 backup, or even 100,000:1. The BOINC manager will ensure the initial backup units are crunched on time, at the expense of making the Long Term Credit (LTD) a large -ve number, so that under normal circumstances BOINC will not download from the backup project unless Seti is down and BOINC decides you need more work.


Or, I could set my cache higher by a couple of days to smooth out the bumps in server-land. That way there, Seti still gets the results of my Cpu efforts. It's not foolproof - there could be a catastrophic failure that results in a Seti shutdown of multiple weeks or months, but for all of the recent bad luck it would have been sufficient.

Of course, I don't mean to sound like the Seti@home staff aren't doing their jobs. I know it's something I couldn't do yet, with my level of education and computer knowledge. As far as I'm concerned they're doing far more than we could have ever expected them to.

Cheers,
Jim
