1) Message boards : Number crunching : CPU & GPU processing of SETI@home v7 7.00 and cuda50 (Message 1408280)
Posted 370 days ago by Profile Rae of Quakesville,CHCH NZ
hi. seti work units vary in estimated computer time. while some units maybe 3-4 hrs, others might be 9 - 12 hrs or more like the astropulse units, which are closer to 55 - 60 hrs on average. Yes your GPU computes faster than your cpu & work unit estimated times also vary a lot in those. If you run only 1 work unit on your cpu, your gpu will complete its tasks quicker still. Since your cpu supports SSE2, I suggest if you want toi complete your work units even faster, try using the lunatics installer v 0.41 whichj has optimized data processing programs for both your cpu & gpu.
Happy crucnching

What about a pci slot card? maybe there are more options with that?

Your other option is that there are suitable PCI cards available with low end NVidia chips in them, but you'd probably have to mail order them from the US or Europe.

Is there a card you can recommend and a place to purchase it from?

The third problem is that for OpenCL to be used with an AMD GPU the processor must have or above, what processor does this machine have?

Claggy


Intel Pentium 4 @ 2.66 ghz ( single core) It does support SSE2. I have already downloaded Lunatics v0.41 & it chugs along nicely for its age.

Hi. I am upgrading an old Dell computer. The motherboard has an AGP port on it.
The desktop runs windows 7. Will either of the following Graphics cards be recognised by Bonic for crunching?

256MB Asus A9550GE/TD/256M (Radeon® 9550) AGP 4X/8X graphics card.

ATI Radeon X800 XT Platinum Edition Bus Type AGP 8x
Vista Capability This video card is capable of running Windows Vista, without any of
the new major features, and is suitable for Vista Home Basic.
Graphics Processor / Vendor ATI Radeon X800 XT
RAMDAC 400.0 MHz
Max Resolution 2048 x 1536 at 85.0 Hz
Max Monitors Supported 2.0
Interfaces 1.0 x DVI-I - 15 pin HD D-Sub (HD-15) ( On supplied cable ),
1.0 x S-video output - RCA ( On supplied cable ),
1.0 x VGA - 4 pin mini-DIN ( With adapter ),
1.0 x Composite video output - 29 pin combined DVI,
1.0 x VGA - 15 pin HD D-Sub (HD-15)
API Supported DirectX 9.0,
OpenGL 2.0

Memory

Video Memory Installed 256.0 MB
256-bit memory interface
Technology GDDR3 SDRAM
Effective Clock Speed 1.12 GHz

if either or both of these are suitible, which 1 would be the better choice?

Thank you in advance

6) Message boards : Number crunching : What is the best way? [Answered] (Message 1398812)
Posted 393 days ago by Profile Rae of Quakesville,CHCH NZ
Are you keeping the hard drive from your old rig? If yes, then all you will need to do is add drivers for any new hardware, the wondows instalation itself might be salvagible.. might save you a few hrs <& a lot of downloading> of install & updates. I too have been rebuilding a pc, a Dell 4600. I found the easist way to reinstall / upgrade windows from xp to win 7 was from a bootible usb drive with all the windows files on it. Be sure to use a usb 2 port for this.

Posted 396 days ago by Profile Rae of Quakesville,CHCH NZ
Hmm, that's a tricky 1. How many cpu tasks are running at the same time as the gpu unit? Since that host has 4 cores, I'd be inclined to try setting max cpu tasks to 3 or less to see if that makes a difference. May Im also suggest openng up your system unit & dusting <especially the cooling fans & power supply with a pastry bruch or similar> & physicaly removing & reinserting your graphics card in case somethng has crept in there. Error checking & defragmenting your hard drive may also be worth a try.

Just passed the 100,000 Total credit mark <excluding classic units> .

Yeah! I managed to find a higher speced cpu for my socket 775! not quite top of the line, but its an improvement. a Pentium d 945 @ 3.4 GHZ 2 core, 2 logical processors..a bit of a step up from 2.8 ghz..

More problems with GPU crunching:

While, for instance, a WU like 17fe09aa.30537.5798.13.12.155_1 (SETI@home cuda42) works just fine I now start to see the same reset problem with other SETI@home GPU WU as well. As a notice known affected WU are:

17fe09aa.30537.5798.13.12.88_1 (cuda42)
18ap08ah.12735.22976.9.12.35_1 (cuda32)

Any idea/suggestions why this happens?


How many gpu tasks are you running at once? If more than 1, drop it back to 1 as your gpu only has 512k of ram to work with. Also, since your dektop has 4 cpus, allow seti / Bonic to only use 3 of them.

Other thoughts, Try closing bonic, exit all tasks & run the Luntatics installer v0.41. you can download that from here
http://mikesworldnet.de/produkte.html Be sure to grab the 64 bit installer for your system as it has 64 bit windows on it.

After restarting Bonic, your tasks should continue where they left off from. Note, future work units will show on the seti site as anoynmous platform.
I suggest, when installing that you select either cuda ver 3.2 or 4.2.

If you realy want to change the priority you need to use a program to do that automaticaly like Fred´s priority tool.

Where do I get that from? I hacve seen inmentioned in many posts but have been unable to locate where to download it from

The advice may well help some other crunchers Bill, who might search the topic. It might even help him with his other project(s). The only other tyhing none of us suguested at the time was a project reset and or reinstall bonic.

If you are using an older machine, my guess is that you are using a 32 bit version of windows. If this is the case, windows will only use a max of 4 gig of Ram & ignore anything above that. Still it is prob worth opening up your pc & dusting all the fans, the circuit boards, addon cards <such as your graphics card etc. You might also want to remove all your ram sticks & then put them back in, in case any have vibrated loose somehow & check your SATA / IDE Cables. Remember to use an anti static wrist strap when handling ram etc & clip it to the desktop case. I use a pastry brush to dust mny pc once a month or so & find it does make a difference. The other thing to try is perhaps running 1 less work units at a time & see if that helps. Good Luck

Hi, where do I set the priority for cpu work units? I have installed luntatics 0.41 & checked the task manager & found the cpu tasks AKV8C_R1846_WINX86_SSE2X.EXE running at low priority. My GPU Task is running at above normal.

Thanks in advance

17) Message boards : Number crunching : Is it simply the wrong question? (Message 1394835)
Posted 403 days ago by Profile Rae of Quakesville,CHCH NZ
I think some here has missed the point entirely.. Running seti or any other project on your pc in its spare time is entirely voluntary. Personally, I don't care if my RAC IS 3 or 3,000,000. That is not why I joined. My desktop may not be the fastest, or the slowest <for that matter It has a newer cpu as of yesterday>; I joined to help find the intigent life that obvously isn't on that planet. For those who want a yard stick, grab a shovel, dig a hole & sooner or later your measuring tape will be too small or you will arive in China <no offence to any chinese readers of this post>. If your want credit, go sit an exam & put the result in your c.v

Yes it is a pity I'm not there. can't seem to find 1 over here for love nor money. It might almost be worth the frieght to get 1 sent here, but would it arrive in 1 piece.
