Message 149690 - Posted: 10 Aug 2005, 13:31:00 UTC

To avoid flame from either direction, I'd like to preclude this post by excluding myself from both the doomsayer and cheerleader camps. Further, I am here for science and I am here for credit.

Now to the point, obviously the multiple recent outages have caused a decent whack of queue on seti's return. I've been watching the validation queue on the status page for the past couple of days, and I'm wondering whether it's actually recovering: two days ago it was around 400k WUs; today is over 600k.

Now it's reasonable to assume that with a recovery comes a flood of WUs requiring validation, but that was a couple of days ago. By now shoudn't the queue be getting shorter?

It seems my laptop alone has over 100 units (a bunch of most-filled pages) dating back around 3-4 weeks; the desktop's got a rather bigger pile.
I have no problem WAITING for credits as long as they will actually arrive - I'm just concerned that this could be in a spiral dive.

BTW, I don't know how people count their pending units - if there's a convenient way I'd love to hear it. "Pending credit" seems to be temporarily disabled permanently (and fair enough if it will create CPU load).

So... I will just keep crunching and maintain a decent cache so as to contact seti as infrequently as possible.

Your concern is mine.
I begin to fear that ceteris paribus the server farm will not be able to recover.
Outages ARE to be considered as well as the steady increase of workload.
If only Seti will not have to limit the number of participants like some other projects do!

It's had some issues before. They have recovered from them. They are testing different machines and connections to fix this issue. I am pretty sure that during the 3 hour outage on Wednesday that they are going to again make a change. It has been changed the last couple of weeks to different machines, etc.

It will recover. When is when they finally have the resources to put more machines on. This will happen eventually, after Classic goes down, etc. Then they can probably get 10 validators or more going. Same with Deleters, etc.

I believe they are doing the best they can with the equipment they have. I have every confidence this will work itself out in the long run.

Yes, it's sad to see my RAC below 200, when I was averaging about 350. But since that number is a moot point, because of all the dependencies, I also am not too worried.

Faith in the developers, and give them time.

Happy Crunching!

I hope so, although i don't see any improvement over the last days with the exception of now working up-/downloads.

Judging by the news on the front page from the 7th, alot of background services were shut off until the demand died down. Perhaps the "demand" was the initial upload and/or download of wu's. Validation & splitting will come back on later.

I don't know how much memory or cpu the validation process eats up. But it looks like they are trying to speed up the whole process.

I haven't seen anything posted saying that this has worked out better for them.
Hopefully it has. If it does work for them, then we can look forward to having a delay each time there is an outage...

I wrote a basic program to get the pending credit for each host.
You can get it here, but sadly it only works on Windows. I just hope it's useful for some people.

One thing some folks appear to be missing in the 'all will be well when classic goes away' is that *if* (admittedly a rather large if) a large proportion of the folks and cpus doing SETI classic migrate, then, while there will be more resources for SETI BOINC, there will be a lot more work for it to do. The BOINC model with the validation process sending out work to multiple computers and then crosschecking for validation does add to the accuracy of the work being done, but it comes at a cost in terms of the amount of processing Berkeley needs to do.

I've no problem with the rationale behind the BOINC process, but it seems folks are placing an optimistic expectation that elimination of SETI classic will resolve the issues that SETI BOINC has with not only handling post outage recovery, but frankly the issues SETI BOINC has when running 'normal' -- the impression I've gotten from reading the tech notes is that even when running normal for an extended period (which has been difficult enough to achieve) SETI BOINC is running REAL close to the edge.



It will recover. When is when they finally have the resources to put more machines on. This will happen eventually, after Classic goes down, etc. Then they can probably get 10 validators or more going. Same with Deleters, etc.

CJSoft UK-

I'm unable to get your program to run. I'm getting the message: "Component 'misnet.ocx' or one of its depedencies not correctly registered: a file is missing or invalid."

Suggestions?

I had the same problem so I picked up a copy of the file at the following site and placed a copy in C:>Windows>System and a copy in C:>Windows>System32 and it ran okay

File..........http://www.x10.crevier.org/homeseer/kb/1013/

Sorry for that. I do apologize. You may need MSINET.OCX. I shall put it in a ZIP file with all the dependencies. This is the new link.

One thing that is going to help the load on seti's servers is the new application that they are currently testing in beta test. The new application will take nearly 50 hours to complete a WU. They are doing more science in the new application.

Fewer connections will mean a lighter load. Plus fewer WU's will also help make the DB smaller which will also help to lighten the load.

50 hrs on which platform? Jim.. you always seem to post from your own perspective! That's what's scary about posts from people who know enough to be dangerous!

Heck I have boxes that will take more than 50 hrs with the current application!

Shake them Pompoms!!

Wow, that's a little hum-dinger! Thanks.
Any chance of the source? I'm newish in VB6 but would love to see what I could add to it.

Sure mate, source @ http://cjsoftuk.dyndns.org/boinc/PendingCreditSrc.zip

The longer run time will also mean results will be in pending status longer and the validators will have to do more work to compare results.

How does this little app work?

Can't really understand the numbers for it..



Care to explaing the really high numbers or something because i don't think that this computer has 160930 credits pending that i compared too..

Mine claims I have 21,999.6667 credits pending. Muchos gracias if I get it. ;)

Actual pending based on claimed credit for my computer is 208.79, but you won't hear me complain if I get 21,790 more. :)
