Message 617408 - Posted: 10 Aug 2007, 5:13:31 UTC - in response to Message 617394.  

Sorry to burst your bubble but did you check the date on that wu? It was not a mb wu. You did get the mb application, but your work unit is from 2000, definitely not a multibeam!

Is there a quick and easy way to tell?

I've got a fresh one that appears to be data logged on March 3, 2007, and which has the impressively far in the future return deadline of October 1 (over 50 days from date of issue). Is this perhaps a multibeam? If not, how to tell?
perhaps a multibeam WU?


I'm not sure without doing some research the exact date that the multibeam recorder recorded it's first work, so I can't say an exact date to look for but yours and Byron's both are one of the multibeam. You can tell by the date as an easy way without reading into header files and such. The date is the first three groups of two characters in the filename in the format ddmmyy. In this case you both have one that was recorded on the third of March, 2007. Most of the linefeed work we are running now has dates in the 1999 to 2001 range.


To tell if it is MB, just look at the graphics (if you have the 5.27 stock app). Those that are MB say that. Those that are not, just say 'Enhanced'.

Never surrender and never give up. In the darkest hour there is always hope.

... If properly done, a shutdown followed by a reset should cause the work units to be resent as "lost work units" and the new application downloaded to crunch them.


Thanks Jim, quite a while before I get to that wu,[ perhaps a full day] will give me time to think about doing just that, or maybe there'll be a chicken update first, fingers crossed.

Yes, but this only works for a wu that is already started crunching. You can't look at any wu in the cache with this technique. Checking the date on the wu's filename will tell you for any wu in the cache.

If it's going to be that long before you start it, just set "no new work" now and let it crunch the task already running. That way the only one you will have the chance to loose is the one wu. Of course this is assuming that the wu in question was the last downloaded, or you only have the two wu's. Matter of fact, if you do start crunching on it before the rest of them are crunched just suspend it and let it finish the others, then make the switch. The only time you will loose is the amount of crunching it does on it before you suspend it (assuming it doesn't error out immediately that is!). Good luck.

Well it's about fourth from last of about 19 tasks, so I have set No New Tasks, and suspended that particular multibeam one, so I guess it should sit there until last, then I'll try the app_info.xml delete and reset.

It's not an error per se. It's what is commonly referred to as a 'noisey' WU, and just means more signals are found than is allowed to be stored in the output data file.

This error msg is quite normal, it is produced when too many signals are found, there is only so much room on the database. Usually when a high number of signals are detected in a unit it is usually from man made noise, radio interference.
You should find that your partner for that unit gets the same -9 error.
If your partner doesn't and you get this situation on a regular basis then it can also be a sign that your computer has become unstable, usually overheating. But this is fairly rare.

Okay, So I have one of these '07 units sitting in the cache of one of my machines. My questions are:
- I am running chicken 2.2B, will it run/validate correctly?
- if it runs, will it run longer or faster than stock 5.27?
- will it give me more or less credit/time than stock 5.27?
Jason

MB wu http://setiathome.berkeley.edu/workunit.php?wuid=146173344

As posted by Papa, there have been numerous problems running the mb units with Chicken's app. Many have run and crunched fine, but many more have not. So it may not validate, or may give other errors. However at this point unless you are willing to do a project reset and take the chance of losing them both you will just have to take your chances with it. I would set "no new work" until you can crunch your cache down and remove your app_info.xml file and let the system download the new app.
If properly done, a shutdown followed by a reset should cause the work units to be resent as "lost work units" and the new application downloaded to crunch them.


Wait a second here. You guys got some links to hosts producing a lot of validate failures of the Coop app on MB data over on Beta? It's not that I don't believe you, it's just that I'm from Missouri. ;-)

I went back and looked over CElliot's host #5903 (the only one I remember offhand), and didn't see any signs of it having any trouble running 2.0 and 2.2B on the MB data while he was running it that way. We're talking around a couple thousand results run this way.

You're so right, the problems I was refering to was for the win95/98 support.

Jason..

I apologize for the mistake. You can crunch right along. The reference to Papa's message refering to the optimized app led me to think about a Windows problem, however the Windows problem is with 95/98 etc. (Half asleep when I read that and been reading too many forum posts for one night! Hehe)

Hi all
I think i've just crunched my first mb wu. however i'm i little confused. It was crunched using seti 5.17 although according to my seti folder i've already got v 5.27 downloaded. it also used simons chicken app and showed up as a seti enhanced application whist crunching i've deleted the info.app xml several hours ago Is all ok or do i have to do something else to get 5.27 to run

You have to clear your work queue, using no new tasks, and then stop and restart BOINC, then allow new tasks. Whilst you still have work using 5.17 on your list it will keep using it.

Hi,
Is there a quick and easy way to tell?

To tell if it is MB, just look at the graphics (if you have the 5.27 stock app). Those that are MB say that. Those that are not, just say 'Enhanced'.

Or look at the name of the WU.

"classic" enhanced:
31mr00aa.9721.15760.1028384.3.230

multi beam enhanced:
03mr07aa.15818.6207.4.4.142

And here you can see the beam and polarisation:
03mr07aa.15818.6207.4.4.142

3 --> beam 0, pol 0
4 --> beam 0, pol 1
5 --> beam 1, pol 0
6 --> beam 1, pol 1
and so on

Regards,
Carsten

All good Jim :D, have only set new tasks so I can let it do the switch later anyway, I'll unsuspend that MB task and let it crunch dry, Cheers !

Or look into WU (this is text file) and search for string <receiver_cfg>
after that string you can find string <name>Arecibo 1.4GHz Array, Beam 0, Pol 0</name> in MB WU or string <name>ao1420</name> in old enhanced WU

Thanks Carsten, I like that way. Two single-digit period-delimited fields just before the last field to the right seems simple enough to look for.

I'm bemused by the October 1 reply deadline, by the way. I feared this might be a monster, but my E6600 core 2 Duo (running 3 GHz on a moderate overclock) thinks it is 70% done with only an hour and a half of CPU time invested.

It makes me wonder whether the variable deadline function has not been calibrated for Multibeam to anywhere close to the previous work.

It makes me wonder whether the variable deadline function has not been calibrated for Multibeam to anywhere close to the previous work.

The splitter calculations on which time estimates are based were developed in 2005 during the early phase of setiathome_enhanced development. There were a few adjustments made subsequently to shift sections up or down, but nothing to change the basic shapes. Eric is aware the curves don't match reality, just hasn't had time to change them.

These 0.405 angle range WUs are estimated quite long. The curve for the 0.226 through 1.127 angle ranges where Gaussian searches are performed is much steeper than needed. Near 1.127 the estimates are far less generous.
