Thanks. At least I know there are lots of others out there. For me its just one more line in the table. It must be more frustrating to those who have far more.

This task was completed and credited back in March 2012. Isn't it about time is was removed from my results by now?

It's doing no harm sitting there really, just taking up a line of screen space in the valid results, but it must be feeling it's age amongst all the newer tasks that come and go quite quickly.

Not been too well of late, but the 'puters still plod along without me bugging them. However I missed this whole discussion.

Put me down for a Medium, for UK delivery please.

(I know it looks like I'm a relative noob, but I lost my original account from the SETI screen-saver days along with a sizeable chunk of my household contents and skipped a couple of years in the process. Insurance never does cover everything does it.)
4) Message boards : Number crunching : Lots of invalids!! (Message 1404273)
Posted 17 Aug 2013 by Profile Len
I think I cracked it with your clues to help.

I have two cards, because the old one still works and I have a spare slot so I left it in. Another project, POEM, couldn't handle the fact that there were two cards, So I set the config to disallow one for POEM, which fixed their problem.

The upshot of that setting meant that SETI preferentially used the other one, which it has used for years. That card runs at a higher temperature, being the older, less efficient one. It looks like SETI was finding errors with that card only. (All the invalids I checked were done on the older card.) I have told POEM to use the old card only now and their WUs don't seem to mind the slightly higher temp.

My Invalid list it falling albeit a little less rapidly than it rose now. If it doesn't drop away fully, I will stop SETI from using the old card even when POEM has no work. IT's pointless using it if so many WUs return invalid. It may be a 'feature' of having two different spec cards running at once on a project.

With the new card warming the back end of the old card it probably runs slightly hotter than when it was running solo. It now only gets used for GPU crunching anyway. All my own graphic needs are fulfilled with the newer card. Neither card is even approaching the manufacturer's recommended high end of the operating temperature. The case has very good cooling and the CPU is water-cooled.

I am suddenly getting lots (700+) of invalid results. I have never gotten invalid results before. Not even many errors on this particular host before. (

Do any of you superior minds have any clue what has gone wrong?

I've not done so yet. It would be nice to have our own @Home grown project to donate spare flops to. But I'm not really in a position to start nudging the PTB.

I just started. 12% through the first two tasks. I've got the Samsung Note set to crunch only when it's plugged in and at least 10% charged, so it will be mostly working on the bedside table at night, but every little bit helps.

Thanks for the heads up. I shall just keep doing whatever my other chosen projects give me, if I can't get enough from you to keep those little crunching things inside the magic box from getting bored.

Its all automatic this end. If there's not enough time needed for SETI, work on other important things. SETI gets the first bite, then the rest fight it out between them.

I now have errors in my results, all of which are down to two periods of server downtime.

Because these appear as errors, I take it that my machine has been plodding away for no good reason.

My 2 cents . . .

Here is an easy way for non-network types to understand it. Suppose you live near a forest. One day you chop down some tress, on your own, pull up the stumps, on your own, fill in the holes and level it off by hand. By using that road you save 30 min off a trip into town. All is good. You tell a few friends about the road and they start to use it was well. With the increased usage the pothole get bigger and road gets rougher and needs more repair. But you feel you’re doing a good thing so you keep making the repairs. Occasionally some one shows up with a shovel, and helps, but mostly your on your own. Pretty soon everyone wants you use your road. Pot holes must be filled in hourly, mud holes show up that must be filled in, and soon there is a two hour wait juts to get on your now, totally over used, totally tore up road. What can you do?? You can can’t build a new road, no money , you can’t hire someone to fix the road 24/7, no money. You simply tell the users to wait and be patient , that you’re working on, when you can.

Yes. Yes you do.

Traffic backs up all the time on overused roads. The road users learn that they either wait to use the shorter, overused road or they take another, less convenient route.

You not only chose to use another route, but also felt it necessary to honk your horn at those waiting patiently in line.

A network, much like a chain, is only as strong as its weakest link.

As someone else has frequently said "You were the weakest link. Goodbye."

I shall wait patiently for something that I believe in to recover in its own time. Meanwhile my insignificant machines automatically get to work a little harder for other causes I believe in, while they are not working for me.

Sadly, these last two days, my PC has got no work at all from S@H. It has done a ton of work folding proteins and putting them away in the POEM draw, but SETI seems to be under the impression I don't want work.

I read my last few requests in the log and was surprised I don't appear to be asking for work. So I tried suspending, then resumin work, but still it seems I am not wanting work!

18/11/2012 13:01:06 | SETI@home | work fetch suspended by user
18/11/2012 13:01:09 | SETI@home | work fetch resumed by user
18/11/2012 13:05:40 | SETI@home | update requested by user
18/11/2012 13:05:45 | SETI@home | Sending scheduler request: Requested by user.
18/11/2012 13:05:45 | SETI@home | Not reporting or requesting tasks
18/11/2012 13:06:09 | SETI@home | Scheduler request completed

What has gone wrong? Anyone know?

I don't think I'm wasting my time. The proteins needed folding anyway, but I have it set so it should only get a quarter of the work SETI does.

Yup, downloading is borked again :-(
and its taken uploading with it just to make sure we have a "good" weekend

... and its not just seti@home either.

I tried rejoining CPDN in order to get something for the CPU cores to nibble on during the day. All I'm getting there is project backoff, yet SETI is able to 'send 111 of those tasks that expire before the download is complete. This after a rash of tiny tasks that take longer to download than they do to crunch.

I could be a happier bunny I guess.

Thanks Richard & Clive. I shall relax and simply consider it a measure of how hard S@H as a whole is stressed. - And the speedy replies as a measure of the enthusiastic community we have. ;)

Posted 17 Sep 2012 by Profile Len
I currently have 53 errors and they are all tasks that had deadlines within just a few minutes of the 'Sent' time. My machine is not up there on crunch time ranking like many of you, but even if it were it seems a big ask.

This seems to be something that is increasing rather than diminishing. It does not particularly affect my stats, and frankly I wouldn't really be bothered if it did, as all I am doing is releasing idle time to S@H. But it seems like an awful waste of valuable S@H Server time and bandwidth to me. It has been happening occasionally for months, but just seems to be getting worse.

I don't nurse maid S@H, so I only ever see these as errors. Therefore I can't tell if it's true, but it appears that if the 'sent' timestamp came when the download started it might even have expired by the time it was on my machine. Even if my machine started it immediately it could not possibly finish by the deadline.

Well, I got them merged.
(I'd already tried, but Windoze had 'helpfully' capitalised the first letter in the new name, so it didn't work when I tried it before posting.)

Now to see if I get re-sends.

Thanks. I shall do that. Shame to waste the processing time, but Hey Ho. I might even garner a positive reply before it runs dry. It got a whole herd of work already.

My apologies to all those waiting on my results.
On the plus side it will now be working marginally faster once I have it fully up to speed again.

This Cruncher is the one affected, so all these tasks will time out. Sorry, but the damned drive just totaled on me but I decided to go with Windoze7 64bit as the replacement OS, so it should run that bit faster than the old 32bit XP OS.

Given the limited bandwidth available and the abilities to analyse data, you would have thought there would be a way to track such a complete waste of bandwidth and stop giving it work until it sorts out its ability to compute valid results.

Sure we will all get an invalid result occasionally, either from bad data or a temporary host-side glitch. So I'm not saying that an invalid result alone should cause one's allocation to be lowered. However there should be some comparison done with valid V invalid results, that affects the allotment and takes it right down to a minimum in cases like this.

It is simply wasting valuable resources that others could put to good use. The system could then send a notification to the host as to why their allotment is reduced.
