Sorry, it was meant as a joke. I realize you have taken time for some thoughtful responses and perhaps shouldn't have been flippant in that comment. Then again, from your responses you believe that others might do well to adjust their perception and I saw that as something you are quite serious about.

I spend time on a thoughtful response, and in exchange you tell me to adjust the dosage on my meds. Thanks.

Maybe it's time for 'distributed-Serving' rather than 'distributed-computing'.....LOL

It is much easier to move a problem around than to solve it.

That's a curious thing for why the "44" group was there.

Let us know how you get on with the Dotsch/UX setup.

Happy crunchin',

I've been seeing some posts about having to add user "boinc" to the group "video" wonder if this is why they were doing that?

Indeed so.

Also double check that there are "rw" (read-write) permissions for the video group for the /dev/nv* device files.

... that machine is both a headless and diskless cruncher. It boots via PXE from a Dotsch/UX server and then mounts an nfs file system on the server. I am suspicious that the binding of the nvidia driver to the kernel isn't happening on that machine... possibly because part of the intrfms stuff is in a common directory on the nfs server that is not mounted once the boot process is kicked off. ...

That you have no monitor connected should not be a problem provided:

1: The hardware isn't being too clever and requires a physical monitor or a dummy vga/dvi plug to be connected;

2: You have xorg (xserver) up and running.

It may well be that the Dotsch/UX setup assumes non-CUDA operation (or at least doesn't do anything special for CUDA).

Hope that helps a little.

Good luck,
Martin

Following those steps got it working... but for some reason I have to run BOINC as root (ie sudo or gksudo) to get CUDA working, trying to figure out what's wrong there (probably permissions on some file).

Well those two cards are sitting in the box... I also bought a used 8800GT and so far I can't get it configured right so BOINC sees it (64b Ubuntu v8.10)... getting pretty frustrated with it.

I also just filled out the RMA stuff on my HD4770 that I'd hoped to crunch MW on a windows machine. New ATI Catalyst package doesn't work with MW and older ones don't know what a 4770 is (winxp 32b). Too bad it's an almost 4850 with much lower power draw. Nice card otherwise.

I have the same OS, I got both of my GTX 260 to show up after installing the CUDA SDK and Toolkit from Nvidia with no problem... make sure you have them installed correctly AND your account can use them (when I installed mine they were owned by root and group video, changed group to my account and no problems).

OK having read thru this...

Can ya'll help me with low budget cards to put into a headless cruncher running 64b Linux.

I found some 512MB 9600GTs for under $75 each shipped or the 1GB models for around $80 each. A 9800GT would run me around $100. For this initial foray into GPU crunching would I benefit more from two 9600GT cards or the single 9800GT? An additional benefit of the 9600s is it appears all the PSUs I have will handle those. I would have to be a bit more selective for the 9800.

These cards are for nothing but number crunching on SETI, Aqua, GPUGrid.

Is there something that can give me an idea of the output differences between these two?

Thanx much.

As far as 'Budget' cards go (for CUDA performance anyways)....the 9600 GSO cards (1st & 2nd Revisions, NOT 3rd) are the way to go.

9600 GSO (1st & 2nd Revision):
- Cheap (under $80 USD usually)
- 96 Shader Cores
- Note desireable by most, so readilly available.

The unoficial 3rd revision of the card/moniker (using NEW stock, not rebranding old) ......uses less cores (64 I believe?), but uses faster DDR3 memory 100% of the time...no DDR2.

The old revisions were based on a 'rebranding' of 86/8800 Series cards for resale in the NEW marketplace of the 9000 Series.

I have tried (and own) 2 types of these cards. A 768MB DDR2/96 Core version and a 384MB DDR3/96 core version. The DDR3 version is a littel faster acording to BOINC by a few GFLOPS, even though is uses less memory.

Hope that helps.

I have 2 9600gts in my second rig and they work very well.
I would suggest having the 2 9600's as it wil give you the
added feature of being able to run SLI if you have an SLI
capable mobo.
Downside is they are onlt 37GFLOPS.
I am running 2 Aqua tasks on the rig with them in and at present
they have completed about 60% and it has taken around 160 hrs still
80 to 100 hrs to go on them.

Well I did have a better PC lined up to buy..but the seller backed out at the last minute, and I looked around some more and I eventually found one on eBay in my price range for using it as a dedicated BONIC cruncher ..

Computer: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=190311749297

(Pictures are at bottom of page)

I'm wondering if I can fit/power..using the stock PSU. A 9400GT and have it stay cool enough to use it as a Cuda cruncher?

EDIT: Never mind, I see there's no Linux CUDA app on the apps page.
Screwed by Microshaft again.

Hi,

I'm not very familiar with the app itself, but this thread at Lunatics might be worth looking into.

Hi, is it a CELERON or PIII ,(the 667MHz) and I would try to use optimized application, as they come in different [i]flavors

Your RAC, a measure of computating, shows you can gain some with an opti-app!
And/or CUDA enabled GPU cards (8800/9800GT{X} etc. Probably 1 667 is enough to drive a 295/280/etc. GPU?!

My QX9650@3.7GHz. takes 0.11CPU to drive a 9800GTX

You'd be unlikely to even find a card for that PC. If I recall very few PIII level Mobo's came with AGP 4X slot. forget PCIe. Do they make a PCI CUDA? Heck the Video card would use more power than the rest of the computer. I'd avoid the though besides he said he's got the PC and just wants to run it for seti. It be like putting pearls on a pig.

Well Some People Have Pet Pigs. I just have my cat - see picture.

I just have a PIII running XP/Home that I just taking up space. I do not pay for electric here and running it to help SETI might be nice, since it was my first SETI machine. Between my 2 gig server and my slow PIII, it could help, even though the PIII would take 3,4,5 times as long and not do Astropulse either. It is an old Compaq Presario that I bartered some tech work for. She got me to setup her new computer and I got her old one with 17" monitor for free. Since I had a 500MHz that would not run more than 20 gig drives, and this one did 40 gig easily (100 gig was max then, it was a good deal.

I remember when 10MEG was a large drive, since most people only had single or double floppies at the time. I have been using (working with) PCs for a long time and feel that if you got an old one that still works, you should use it.

So 2 gig server, maybe 667Mhz PIII Compaq Presario, also I might get my spare 1 gig AMD Athlon XP/pro laptop and my 2 gig Vista Home/Premium involved part-time.
