I just downloaded and installed the Boinc software, but I assume that with the server situation nothing will happen until next week, correct? Sorry if this is the wrong thread, SETI@HOME newby.


You are partially correct. There is nothing that will be happening with SETI; however, there are other projects to which you could attach until SETI comes back online or in addition to SETI.

Will it do any harm to leave the auto-update on Boinc running? It would be great to get work soon, my latest is ay 90% complete now.


When you say "auto-update" I assume that you are talking about the ability of Boinc to periodically poll the server to see if there is any work. If so, then no, it will not hurt. In fact, this is a prime example of why Boinc was built with this (and other) features. It was designed to be able to withstand downtime by projects.

I,m not sure where to take this, but being a seti user since 2000, i feel when the program changed to Bionic our old classic seti units should of been converted to bionic credits.
Rather than just stating OLD classic total :(, anyway im sure im talking to myself, i just keep losing interest in seti now, i wish they thought about it a bit more.......


Just an old user not happy........



this issue has been discussed ad nauseam. There are lots of reasons that seti classic could not be converted to seti boinc. If you feel so inclined, you can do a search of the message boards and find all the reading you can handle, and then some.

Good luck on finding the answer to that for which you seek.

The thing is, why do you even worry about the project being problematic? BOINC was designed to be fault tolerant. BOINC works through these types of problems with little or no problem with no user intervention.

Indeed -- Einstein had what seems to be the same problem.

My own approach (not sure if it has merit) when I see the 'uploading stalls' syndrome is to suspend the offending project (I've no workstation with less than 3 projects running) and then check back on the workstation. Eventually the upload clears (in anywhere from 6 to 48 hours). When the upload clears, I 'unsuspend' the offending project. Trying to 'force' the upload by pushing a retry rarely seems to work for me.


My machines are stalled also both wintel and linux, with a spread of client versions. I'm running on cashed units and that ain't massive. Look out Einstien here I come!

Einstien also had simmilar problems over the weekend until someone on the project went in on Sunday and gave the servers "a good talking to"lol.

I like the way Arizona does it.. no DST at all.

The reservations in AZ do observe DST. I also think Hawaii does not do DST. There is a few cities in IN that also do not observe DST.



Not true anymore. Indiana went to DST as of last year. Personally, as one who went from no DST to now using DST, I hate DST.

[EDIT]
Opps. I didn't read all of the thread before I posted. I see that someone else said basically the same thing I did.

They're normally used with a "passive backplane" motherboard, i.e., one without its own main CPU, that handles power distribution and (sometimes) storage and I/O control. They're normally installed in rackmount cases for industrial use, and there are a variety of different configurations - often the passive backplane is "segmented", and one PC card is used on each segment, with one or two extra slots available per PC card. In some cases, each master plug-in card is actually a complete PC, with its own CPU, memory, video, I/O, and often even storage installed, with no additional peripherals necessary. There may be versions that would install on a standard motherboard, but I'm not aware of them. Down side is that since it's an adaptation of current technology, the CPUs available generally lag current state of the art by a year or so.



I looked all through the link that you provided earlier, but saw no price list. What would a typical backplane mobo and a typical "single board computer" cost separately? The application that I have in mind, I wouldn't need but one hard drive on a server and the rest of the computers would be booted to linux over lan. So, sound is an unneeded option. video would rarely, if ever, be needed.

I think I'll do some more searching to see if I can find any more information.

Thanks. :)

Jim

**edit**
I found one website. I spec'ed out a 3.2GHz, with 2 Gig mem, no flash mem and no OS. Their website quoted a price of $1,700 for the single board computer. OUCH

maybe this isn't the way to save money.

I myself just wish they would come out with a good general crunching board. That would simulate or be a standard CPU.
They're available, just expensive - for example: (link)


ok.. please forgive my ignorance on this subject, but what would be a typical setup for using this type of board?

would someone buy an "off the shelf" motherboard, and then fill the PCI slots with these boards? If this is the case, then would this then be bascially 3 or 4 or 5 computers in one? or am I just way off base?

Thanks for the info.

This dish is fixed however the recieving antena(sp?) moves. So there is some range of 'movement' it is a fairly narrow band in the northern hemishpere.


this is also part of the reason why they want to use a dish in the southern hemisphere. Some work had been started, but later stalled. Right now I don't remember what the show stopper was. Probably money.

It appears that your client may be working in Earliest Deadline First (EDF) mode. I am guessing this because of this line "16/09/2005 19:21:41||earliest deadline: 1148598786.000000 06xl_000034011_0"

Are you running other projects on this machine? What kind of deadlines do those WU's have? etc...


I running also climatprediction.
How can I change the mode in order to not be in EDF mode ?

I have also this message :

19/09/2005 19:20:39|SETI@home|Requesting 0 seconds of work, returning 0 results

Why requesting 0 seconds of work ?


Your computer thinks that it has too much work to complete all of it before the deadlines. Because of this, it is working on the projects that have the closest deadlines. This is also why it will not download any new work. No need adding more work that can't get done. Without knowing more information about your computer, your version of Boinc, etc, it's hard to say what to do next. You might consider browsing the WIKI to get some ideas.

Glenn,

no worries about the question. I'm just glad that I can help you.

I went to the WIKI and typed "RAC" into the search box. I got the following link: http://boinc-doc.net/boinc-wiki/index.php?title=RAC

that page will tell you everything you want to know, and probably more.

If you have any further questions, please feel free to ask them. I will admit, though, that some people get a little testy when questions like this are asked in the Science forum.

HOpe this helps.

There is a new Seti project app that is currently being built. It is in the Beta stage at the current time. There are still a few errors that need to be found and corrected. It is in the works, but not yet ready for full public use.

As far as what Berkeley has in mind for the data, I don't know. Some have hypothisied that we would be re-crunching all of the data. I have not seen any official word from Seti about that issue.

Have you changed anything recently on your computer or on your internet connection?

You could try to go to boinc manager, Projects Tab, highlight Seti and press "Update" This will force an immediate update rather than waiting the 5 days that is mentioned in your log file.

Good luck. Also, if you come up with any new error messages post those, too. Any other info that you might think helpful, feel free to share it.

One benefit to the project of dropping the issuance of a 'initial 4th result' would be to decrease the number of files in the download directory by about 25%, assuming the number of issued work units is constant. This would help with the current problem of 'too many files' in the download directories, and give the project a little more room to grow on the current disk hardware.


Actually, I think it would have the opposite affect. Instead of decreasing the number of files, it would actually increase the number of files. The problem they found was that a large percentage of results were not being returned, therefore the WU's had to be reissued which added another 2 week delay. now we have those files on the RAID for 4 weeks (and sometimes more), whereas if they issue 4 initially, but only 3 get returned, they still get a quorum and the files can be deleted after the initial 2 weeks.

So, by speeding things up, they can get the results validated and removed much faster, thereby minimizing the number of files on the RAID.

This has to be impacting the server and the network traffic. The user's other computers seem to be ok. This one however is not...


and why is it not being penalized for those invalid results? I thought that invalid results caused the number of wu/day to drop by something like 50%. at this rate, this guys should be at "1" or close to it.
