Articles
First Extragalactic Planet May Have Been Detected - Not a SETI-related article, but I thought it newsworthy!


Run SETI on a GPU? Add your SETI username to this thread to be included in future news posts as a GPU user. Also add your name to the same thread if you’ve stopped running the GPU client so I can take you off the list.


The stats are a bit misleading this week because of the problems Berkeley have had. They're in the process of sorting it out, so hopefully the news post next week will be back to normal.

However, I'm afraid the inevitable stomp by TeAm AnandTech happened this week, pushing us down a place into the familiar territory of 16th.

As always, congrats to all the tiffy winners and a warm welcome to our new member!

I recognise a user on that list. Consider my nine-month duck broken. Won't be breaking any records though as it's getting a quarter of a Pentium 4. :D

(SETI@home Beta is getting another quarter, with Rosetta and CPDN taking the rest).

Thanks for the news TT, and well done to everyone for the tiffy's, what would we do without CUDA :D
Click to expand...

Hi,

I don't want to sound ungrateful towards CUDA because it got me out of 'retirement' and back crunching again at a far faster pace than expected even. Getting it to run reliably has been and still is to some degree a real pain for me at least.

Hopefully someone will chip in with a 'mine runs fine comment, never had any problems etc' and I can get some advice on where I may be going wrong.

Scheduling Problems encountered have mostly been solved progressively with new releases of Boinc, version 6.6.36 now makes separate requests for GPU & CPU work and also seems to keep my cache settings of Four days to a realistic level which is good.

Physical problems with keeping everything working and cool 24/7 have improved and with my new watercooling setup I now only get blasted by 65c air rather than the 90c treat I had before. Who needs central heating, with a humidifier and some imagination I could have a replica rainforest in here.

What troubles me now is GPU wu's 'stalling' if that is the right term. Boinc will show an elapsed time of say 00:45:25 and 00.000% progress, this happens reasonably often and will continue in it's static state until I intervene usually by exiting and restarting Boinc. Alternatively I can manually abort the unit but the other option of suspend followed by resume doesn't normally do the trick.

My example of 45mins is only that, yesterday I came back from work and they were stuck idle for 6 hours! saves the electricity bill if nothing else but it is frustrating having invested time and money in the hardware to have it sit idle for so long a period.

Cheers, Simon.

PS. edgedemon sorry for dumping my problems on your light-hearted comment :)
 
The only problem I have been having is that my second-faster gfx card (8800GTX) doesn't seem to want to download units, so is inactive. I'll try the new version you mention and see what happens.

No worries Simon

Im not sure if it is related, I don't get units stalling, but I do get a few that come back with 'computational error' and abort at various stages in the crunching process.
The guys over at lunatics have a unified installer which has made a difference
http://lunatics.kwsn.net/index.php?module=Downloads;catd=9
You exit seti, run the installer and it installs the optimised apps for you. One of them is a modified cuda app which kills the low angle VLAR units (I think thats the term) which are known to cause problems for GPU crunching. I cant remember ever having stalled apps, but i do get less computational errors since using it. Im also running 6.3.36 and the latest version of CUDA
Im with you on CUDA problems, it is a pain, but like you, its has got me back into my crunching so Im willing to fiddle a little bit.
Dunno if this will help you, but I hope so...

edit - have you tried the seti forums as there are posts on stalled workunits?

Thanks for the help guys,

Been looking on the Seti forums and found a few references to similar problems but no real resolution to them.

Also happening today is that a lot of the GPU work units (180 so far) are being started and then shelved as 'waiting to process' but a portion of them are still showing in the task manager as active and consuming memory. There was a post on this very problem again on the Seti forums but no instant cure as such.

I am currently running the Lunatics install on XP64. Going to back it up, delete the exe's and dll's and re-install to see how that goes. After that I may just revert back to an earlier version of Boinc.

Backed up and went back a couple of versions to 6.6.20, this seemed to settle things down a bit.

Cheers, Simon.

Hi,

Just catching up with my GPU 'stalling' problems which were self inflicted :o

Switching to the earlier 6.6.20 version of Boinc cured the problem of large numbers of partially completed work units being shelved as 'waiting to run' but I was still seeing wu's fail to start with elapsed times up to 10hrs or more but no progress shown, see the pic below for an example.

Boinc1.jpg


With the current weather the pc has been generating too much heat so it was either turn it off or turn it down. Understandably I couldn't bring myself to turn it off so it all went back to stock speeds (I know I know it's the Overclockers forum) but the upshot is no more stalling work units.

Just need some time now to work out what was too high and where the limit is.

Cheers, Simon.
 
Well I've reluctantly decided to suspend both my machines from running Seti because of the ongoing problems they seem to be having with sending/receiving work units - been going on now for 2 weeks and still not fixed.

Going to switch my machines onto some other project - possibly Einstein - rather surprised that OCUK does not have a team in that?

I threw a tantrum :o today and detached with 140wu's waiting to upload, sorry about that but pretty much fed up with all the problems as well. I even found myself reading the Folding FAQ's for SMP and multi GPU before re-attaching.

Having run Seti for almost Ten years I don't want to do anything else but I do get frustrated when the time, effort and money I volunteer go to waste. especially as I have a third GTX295 ready to go in and an alternative motherboard, purchases which have all been motivated by Seti.

Mini rant over, Simon.

sorry to lose you from the SETI team but fyi OCUK does have a team for Einstein

Same here Simon - just swapped my graphics card for the GTX 285 so could do Seti on Cuda but enough is enough.

Been with Seti since May 1999

Hi Sorry I haven't responded but went for a trip down to the Shop (Overclockers) and found they had moved! the guys from the Tile shop opposite gave me directions so all was well in the end.

Picked up a few things to help with the updates and stripped the computer down as soon as I got back, 12hrs later and it's up and running with a re-plumbed cooling system that I am still not happy with, a new motherboard (Asus P6T6 WS Revolution) and another GTX295 which I bought from the forums last weekend.

Sorry to hear you are moving off Seti (hope it is just temporary) but glad to see you will still keep the team going with Einstein.

Well my mini rant didn't seem to last long it was kicked off by slowly running out of work last week, but as Biffa posted they got through in the end and I ended up with a good batch of GPU work to keep me calm:D

Taking a new tack at the moment and only running GPU for a week or so to see how the GTX's run on their own without contention occuring with the cpu work. As it stands cpu usage runs between 15-30% just feeding them all.

Cheers, Simon.
 
One for SimonB

I noticed a post on the seti forums, cant link to it as they are down at the moment.
Its an app that runs a perl script that identifies VLAR/VHAR wu's and switches them from your GPU to CPU so that you no longer get the errors or units hogging the GPU.
Its called ReSchedule1.8 and its really good. I had to install boinc over the top of my existing boinc as I didn't have app 6.03, only 6.08, and it found 22 VLAR's and switched them to cpu crunching on the 6.03 app. In addition, if the scheduler downloads too many CPU MB units, it can re-schedule them for crunching on the GPU if you get low or run out of CUDA units.
Its cool :D

Steps taken

Re-install BOINC
Reinstall optimised apps via the unified installer from lunatics
copy ReSchedule1.8 to the data diredtory, though Im not sure that is needed now (it was in 1.7)
Run it

If you haven't cleaned out the stock apps to use optimised, then I dont think you need to re-install boinc..
 
Hi,

Yes saw this and gave it a go, very tidy app although it didn't save me from running out of work. Managed to get things uploaded today and even got a few cuda wu's but these are now stuck and waiting to upload.

A really bad week for me on the production front :mad:

Cheers, Simon.
