1) Message boards : Number crunching : What Motherboards are you using? (Message 1286855)
Posted 675 days ago by Profile Konata Izumi
I use Gigabyte, MSI, DFI, ASUS, AS Rock, Biostar, Supermicro... In about that order.
The Gygabytes have generally given me fewer problem, the ASUS have always been a little "tweeky" for me, although they seem to keep working. I've used various Intel and AMD sockets and currently have a working example of all the different memory types from DDR to DDR3, Socket 775 & 1155, Socket 939 & AM3.

for the newer folks to BOINC and seti@home, The admins have made a point to tell people that there will be times where seti@home has no work. They have always said to have a backup project or 2 to fall back on when work is scarce.


It seems like we get to switch projects once or twice a year when Seti gets slow for some reason or other...
You get to do lots of volunteer work for different people...


I gotta install a new mobo on one of my machines pretty soon and I like to break it in with a couple of weeks of crunching if I can . . . unless it's winter, then it's crunching until it get warm again, (outdoors).

I think it was one or two winters ago almost every other project I tried was having problems... when Seti was down for some reason...

heh

Lt


As a "daytime sleeper" . . . that's the biggest reason I keep mine going...
. . . takes away the road noise...

I looked and that GTX460 Razor takes two PCI plugs so you might not be interested...

Galaxy has a GTX460 card called the Razor. It's a one=slot card but the last time I found one it was over $200 USD. I haven't seen one on line for a couple months now.

I've been running an ASUS ENGTX460 DirectCU TOP/2DI/768MD5 for 3 months solid 24/7.
My RAC has been around 14k to 15300 . . . until today I was using Lunatics .37...
I just loaded up .38 & I'm interested to see how it works out.

This is on my "HTPC/TV" PC, so it does double duty recording my TV shows and crunching BOINC/Seti.
I don't bother to over-clock but this card already runs at 700MHz/1400MHz.

I keep seeing a Sparkle Refurbished for $100 that looks tempting... I've generally had good luck with refurbs . . . Pre-disastered . . . at least you get some sort of warranty...

Another thing I've been thinking about is one those GTX 465s . . . but that's another story.


Why a 465? They only have 18 more cores, run way hotter, and aren't as overclockable.


I can buy them cheaper . . . The other thing, on start-up BOINC says my GTX460 can do 627 GFlops, the GTX465 in my other PC can do 855 GFlops.
(The GTS450 in that PC with the GTX465 can do 435GFlops.)
Yes I know those are estimates... but it's interesting to figure the possibilities.

Besides the 465 only get about 7 or 8 C hotter than my 460's...

If you can get a refurb the 460's are hard to beat but the new ones are getting to be kind of ridiculous hovering around $160 . . .
. . . rebates are a lie, at least for me... I ALWAYS get screwed out of rebates.

While we are talking about GTX460's can someone solve my confusion please:

I've just had a look at the various offerings around I see there are several different specs for this card. My brain can cope with the various clock speed offerings (in crude terms faster clock = faster processing), and memory size (again the more the better). But my brain sort of splutters when I see two different core counts - 288 and 336 - surely there is only one core count for the '460? Or am I missing something?, or is this a red herring, and the lower count isn't actually a "proper" '460?

There seems to be a GTX 460 SE with 6 Streaming Multiprocessors instead of 7 - that would account for the missing 48 cores.


I thought the "460SE" would end up being a economy 460 . . . but everywhere I look they seem to be as expensive as the regular GTX460s.

Is it me or are the prices going up on the GTX460 card lately?

I gots lots!!!

I can keep my apartment warm again!!

Thanks for all the hard work!!

Merry Crunching!
9) Message boards : Number crunching : What is your power bill (Message 1052069)
Posted 1337 days ago by Profile Konata Izumi
I use seti for my primary heat source in the winter...
When I have everything going I usually end up with a $125 to $150 a month power bill. If I get down to two units crunching, like in the summer I can drop down to $85.

Ever since the Great Outage *lol* it's been kind of tough to keep the house warm when it gets down into the 20's (F). Some projects seem to have a limited amount of WU.

I think my cost is about 7.9 cents per Kw.

If I take a lot of long warm showers and bake a lot of pizza, I'm sure that can have a cumulative effect too.

I'm down to nothing but CUDA WUs and I can only do one at a time . . . instead of two or four . . or five...
Been farming out to other projects . . . seems like this happens every now and then.

Curing cancer and growing virtual plants is still good science.

Posted 1368 days ago by Profile Konata Izumi
I've got a PC on World Community Grid and I'll bounce around to just about everything that has been mentioned just to "do" something....

I like Climate Prediction but the WU/tasks can take a Llllloooonnnggggg time..

Virtual Prairie is nice . . . quick little WU/tasks.

I have a listing on my team page of all the stuff we have done . . . more than 20 projects.
I used to have a link to massive amounts of BOINC projects . . . I think there's list on the Wikipedia "BOINC" page

Posted 1626 days ago by Profile Konata Izumi
The only reason I could see a low default setting like that is for the odd lap-toppers that actually run BOINC.... *sarcasm*

. . . .That'd be about 4 or 5? *more sarcasm*

I wonder if it's more to give people who use their PCs for work or telecommuting the feeling that they can contribute to science and still not feel like they just "time-warped" back to the days of Windows 98 and the jittery/choppy/slow CPU experience......

That is a reason I could understand.

MOst of the people I talk to are interested in getting more BOINC WU done than anything else.

;)

Posted 1670 days ago by Profile Konata Izumi
1/1/2010 8:42:36 PM NVIDIA GPU 0: GeForce 8800 GTS (driver version 19562, CUDA version 3000, compute capability 1.0, 320MB, 228 GFLOPS peak)
1/1/2010 8:42:36 PM NVIDIA GPU 1: GeForce 8600 GTS (driver version 19562, CUDA version 3000, compute capability 1.1, 256MB, 93 GFLOPS peak)

I have a GeForce 8400 PCI that seems to get the same 22 GFLOPS peak as my GeForoce 8400 in PCIeX16 . . . In different PCs...

The PCI 8400 is running with a 9600GSO card in PCIeX16. BOINC seems to think the 9600GSO can do 264 GFLOPS peak with driver 19562.

Another PC with the same 9600GSO Card (ASUS) the BOINC client gets 47 GFLOPS with the 19107 & 19562 driver.

?????
*sigh*

14) Message boards : Number crunching : Have two different CUDA cards, would like to crunch with both. (Message 960028)
Posted 1670 days ago by Profile Konata Izumi
Wow . . . that was pretty easy..

I thought I had to actually find an XML file named "cc_config.xml", that link cleared it up. I just typed it out on Dreamweaver and saved it to the BOINC data file..


Thanks much!

Posted 1670 days ago by Profile Konata Izumi
I have two GPUs (not in SLI), an 8600GTS and an 8800GTS.
When I start the BOINC manager both cards are listed;
Nvidia GPU 0 (not used)GeForce 8800GTS
Nvidia GPU 1:GeForce 8600GTS

How can I get BOINC to use both GPUs?
{If there is a way}
I tried using optimized app.s from Lunatics but it doesn't seem to change the ability to run more than one GPU.

Do I have to have identical GPUs in order to use both?

Can you help me out?
