1) Message boards : Number crunching : nVidia driver 275.33 (Message 50544)
Posted 5 Aug 2011 by pieface
Hmmm... Maybe I should have read this before I installed 275.33??

I had been noticing that my GTX 550 ti was only reporting about 730mb of ram (vice 1,000) during Boinc startup, and after looking around on the internet, discovered that this was a known problem with this card and CUDA. NVIDIA was supposed to have been working on a fix back in March, so I figured I would install the latest drivers and see what happened.

OOps... Boinc startup now says 961mb (much better), but when running MW it now seems to eat-up a full CPU core ((i.e. 8pct of system on my 980x)) to do a GPU unit...???

Anyone else noticing this kind of behavior??

Sorry, I had already aborted them when I checked the message boards again. I ran some different projects overnite, still getting the new machine identified to all the other projects I run and didn't encounter any problems.

When I came back around to MW this afteroon it merrilly downloaded the whole spectrum of types, GPU running in around 10 mins, multi-thread running very quickly also (using all 10 'cores' that I let Boinc have) and now the single threaded ones are starting to run their chunk of time. I have no idea what it could have been, probably something related to running with a useable GPU for the first time got it confused.

Thanks for all the time!! Hopefully this was a one-shot wonder and won't happen again...

Oh well... took a couple of hours to do the shut-down/re-start as Mr Softie decided he just had to co-opt the machine for updates. Situation is still the same, seven CPU n-body 0.66 MT WU's sitting there all by themselves in 'ready to start' status, but none of them running. I am going to Abort these WU's and see what happens with another batch later. At least that way they will get re-sent to someone else.

No error messages that I can see in the Log, every time a GPU unit finished there was a schedule request for more GPU work, usually only one more unit downloaded with a message saying the unit had reached the max-tasks-in-process limit. I have one more Rosetta WU running on the CPU at 99.84 pct. Once that one is finished and uploaded I will exit Boinc and bounce the machine to see if maybe the GPU WU's locked something up.

All of the GPU units processed (and most merrilly went off to la-la-land)...

It's the multi-treaded CPU units that refuse to run at all...

I recently received a new computer with a GPU that could crunch MW, so I merrily downloaded Boinc and signed up for MW. Sure enuf downloaded a bunch of MW GPU units and a half dozen or so of the N-body 0.66 Multi-threaded ones as well. I figured all was well as the new guy is a 6 core (12 w/HT enabled), but... The GPU units all crunched but not one of the MT WU's. I downloaded some Rosetta and some Enigma WU's just to see what would happen and they all crunched merrily to completion, but the N-body guys haven't budged a bit.

Any ideas???

The 'Prez' is visiting the NY Capital region today. He gave a speach over at Hudson Valley Community College which isn't all that far from RPI. Maybe the folks over there took a 'holiday' to avoid the traffic tie-ups and other craziness that usually accompany this sort of visit...
8) Message boards : Number crunching : 'phantom' computers assigned wu's? (Message 1107)
Posted 16 Dec 2007 by pieface
I put a note about this in the website forum yesterday as it didn't seem to be interfering with crunching, but... After deleting several 'phantom' computers last nite, I found two more in my account today. Valid CPID 1134 has spawned two new phanton id's:
3792 and
3818 the difference being that now these two 'phantom' boxes have been assigned wu's that the real box knows nothing about?

Posted 15 Dec 2007 by pieface
I dunno if this is just me, or maybe something in the BoincStats / Boinc Account Manager handshake with the site, but it seems like every time the milkyway servers crash and come back up I get a set of new computer id's in the list for my account. all show as never having contacted the server and of course zero accumulated credits. I just finished deleting six or eight of them.

Hmmmm.... if a 400 sec wu gets 2 'credits, then I don't think the proportion is correct when an 1200 sec wu gets 4.86?

400 sec and
1200 sec

but hey.... there's snow out on the hill's...

Hmmm... did you purge the DB of completed wu's at the same time or something? The only wu's left under my account either had trouble downloading the new binaries or are 'phantom' wu's that never made it to my machine. All of the valid work is gone....

I did a project 'reset' followed by a scheduler update, looks like it went fine communications-wise, but no new program and no new work came down the pipe.

Hmmm... how about making the WU's 50x longer, that would sure save a lot of upload/download on multi-core machines, I think one of mine went thru four or five hundred wu's yesterday (counting the ones that choked on download). I'm sure this must be stressing your servers as well?
