GPU Credit adjustment

Mine ALWAYS shows an estimated time of more than a thousands hours. 

But the longest one took a little over a day

Running BOINC 6.5.0 (64bit Linux) on that box.  Nothing in the cc_config file as far as # of processors goes but it's always running 1 GPU and 4 others.  GT9800 card

Don't ya just love it when the latest file downloaded from GPRGrid says that it has a completion time of 48 hrs?? Not even a 280 could process that within 24 hrs *GRRRRRRRRRRRRRRRRRRRRRRRRRRRRR*

Hey, I have been getting some with an estimated completion time of 110 hours! Go figure how you return that within the deadline of 4 days! Mind, you I did manage to process one of these in 110 hours, and even though it was half a day beyond deadline it still got credit.

110 hours  :thumbdown:  I thought it was bad enough getting a 26 hour WU.  Must be part of a cunning plan not to pay the bonus biggrin

update - looks like it will run in about 14 hours - BOINC estimate a bit wonky again

I have a 9500GT in one of my linux boxes, but cannot get GPU grid running...

It will be slow, about 3 days on a long wu.

Use 177.82 drivers with 6.4.5 boinc client.

Are you on Ubuntu?

veebee

Yes, Ubuntu 8.10.
I think its an issue with "libcudart".. though I just put a copy of it in /var/lib/boinc-client/ which is where I think its supposed to be ... still no good after a restar of client..

I kno wit'll be slow, bu tit's better than not crunching at all with the thing... - though, I suppose I could do F.A.H.

Methinks me needs to get a GT250 minimum.

8800GT is good for two wu's a day.....good card for the money if you can find them used.

I run 8.04.  Just put your boinc client in a folder in your home folder.  Run it from there.  It will have to be started manually[boinc manager] each time unless you go to "sessions" and have it start there on boot[boinc clent and boinc mgr].

veebee

has started running overnight... seems to be the story - people (not all obviously) hook up to GPU grid and their comp "doesn't recognise cuda devices"... then a while later.. VOILA ! its crunching GPU grid !

MAGIC !!!!

Be careful with 8800GT - I think that the earlier ones using the G80 chip don't support the level of CUDA (1.1) used by GPUGrid - see (see this thread).

Also regarding GTS250, I think GTX 260 may be better bang for the buck if you can stretch to the extra $$.  Have seen them for just over $300 and should crunch GPUGRID significantly faster than a 250/9800GTX+. A 260 is nearly twice as fast as a stock 9800GT (in the area of 7 to 8 hours per WU).

Also in terms of future apps, keep in mind that the 250 is really previous generation technology (essentially a faster clocked dye shrink of an 8800 GTS) and doesn't do double precision floating point, unlike the GTX 260 and above. Milkyway for example requires double precision FP, which is the main reason the high-end ATI cards (which have very strong double precision FP) have a client, and CUDA does not.  When a MW CUDA client does happen I expect it will only support GTX 260 and above, not the 250 or any other 8 series or 9 series cards.

The 8800"GT"/"GS" is ok,8800 GTS/GTX/ULTRA are the ones to avoid.

Does that suggest the GeForce GTX 295 at $AU771.00 is the best one to use?

I wouldn't say so unless you have a PSU that can handle the load...  And it depends on whether you want one or more GPUs.   

That's one of the reasons I'm considering getting a 9800GT (around $170-180 each) in each of my quads, rather than a single GTX 260 (around $330) in one of them.

Put another way.   If I were to put a GTX295 in one of my boxes, I'd have to also spend upward of $200 to get a decent PSU (like a Corsair HX620, Zalman ZM600, Coolermaster M620 etc)

Mike Mitchell

While I have two decent power supplies I didn't really want spend $AU771.00 but it's nice to dream.  biggrin

Yeah, nothing wrong with dreaming.  Get a mobo with 4 PCI Express x16 slots and put a GTX295 in each :)   Would have to have an i7 CPU at this point (or a dual socket quad core Xeon/Opteron) to get work for each GPU!

Mike Mitchell

Now that's the way to go. If I win tattslotto I'll be straight into it.
