Post:
It's a 3rd act plot twist I could have done without, that's for sure. To answer an earlier question I think I'll just go for a new CPU for the moment.

Makes sense about the cc_config file and identical cards, though, if that is the case.

It's all knowledge and experience which I can pass on if I see someone else in the same situation.

Thanks, all.

OUCH That's a nasty turn of events! Sorry to hear that.

I heard someone mention that you don't need <use_all_gpus>1</use_all_gpus> IF your cards are identical, or very similar. That must have been what was happening before.

It worked for about 5 minutes. I was writing a reply explaining I somehow missed the <use_all_gpus>0</use_all_gpus> directive at the bottom of the file (obviously over-riding the <use_all_gpus>1</use_all_gpus> I put earlier in the file) when...

My CPU gave up! (logic board reporting through a hex code display that the CPU is not initialising and a very prominent and red "your CPU is fried" led)

But that's a whole 'nother story...

What I don't quite get is that I never edited the cc_config file when I was running the 2 x 750Ti - so it must have had a <use_all_gpus>0</use_all_gpus> directive - yet BOINC/Seti@Home used both GPUs.

I see it is working now

Thanks for that.

I didn't have <use_all_gpus>1</use_all_gpus> in cc_config and adding it has made no difference. (It worked without it with both 750Ti, though)

I've re-installed the optimised apps and twiddled with app-info.xml to no avail.

We'll see if any genius can spot what I am sure is obvious. I just can't see it.

I'll re-install the nVisia drivers, if that doesn't work; back to the 2 x 750Ti

It sounds like your cc_config. Do you have <use_all_gpus>1</use_all_gpus> in it under options?

If not that, did you re-install the driver after adding the card? Clean install of course.

OK, so it's been a while. A long while. Hi again guys and gals!

I've recently sparked up Outlander after a year or so of down time and am back into the crunching frey but I have encountered a bit of a problem which MIGHT be a case of "Your Graphics Card Is Too Old" and I'm willing to accept that... Begrudgingly.

I have 2 x nVidia 750Ti which crunch away happily, albeit not as fast as I'd like, so I found the old (1st gen) Titan which I used to use, stuck it in the computer, and tried to get it to crunch.

But it won't.

12/05/2017 20:30:44 |  | CUDA: NVIDIA GPU 0 (not used): GeForce GTX TITAN (driver version 382.05, CUDA version 8.0, compute capability 3.5, 4096MB, 4010MB available, 4707 GFLOPS peak)


I have a feeling that that 'compute capability 3.5' is the kicker here. I'm probably missing something about Hardware version/Driver version too. At least that's what my gut tells me.

-I have the Lunatics 0.44 optimised apps installed in Windows 10

-My app_info.xml has each GPU app set with an avg_ncpus of 0.25 and a max_ncpus of 0.5 (we can debate the wisdom of that later unless it's directly related to the issue at hand :-) ).

-I DID install the optimised apps BEFORE swapping in the Titan, I am going to re-install them after I finish this post to see if that makes any difference. I'll report back.

The Titan seems to be working in all other respects. It'll drive a monitor, the nVidia GeForce Experience application sees it and Device Manager reports it is not throwing any hissy-fits. Well OK, it actually reports "This device is working properly."

Other than that, welcome back, me![/b]

Ouch!

And this, children, is why we make backups and snapshots frequently and regularly!

Glad to see it was just a server and didn't spread to people.

Whoever's server that is though, they must be a bit miffed!

Post:
I'll throw my hat in with the 750Ti crowd. I have 2 of them and they're doing a very good job.

The main win with them is that they are bus powered, meaning they don't need their own dedicated power feed from your PSU, they get all the power they need from the PCI slot itself. This means they (technically) can't draw more than 75W which makes them very power efficient for the work they do.

Having said all that I'd also take heed of what others have said in the thread which is if you have AMD then stick with AMD in the same computer, it's probably going to cause you a driver related headache to mix and match AMD and nVidia in the same machine.
11) Message boards : Number crunching : Why even do this? (Message 1723528)
Posted 8 Sep 2015 by Profile Woodgie
Post:
For me the point is "Because we can." We as humans have always sought answers. Our curiosity and wonder has driven us to aim for the second star the right and sail straight on until morning. It's what got us here and will get us there, wherever 'there' is.

What has been gained? Science, data. I believe SETI@Home has discovered a couple of Pulsars/Quasars (correct me if I'm inaccurate here) and corroborated other astronomy data too.

Even with 'nobody checking the results' the cleaned up data is there to be checked, maybe not now but it's there and CAN be checked. That is incredibly important. It's also very expensive. So understand that it's not that no-one wants to check it, it's that checking it will cost a lot in manpower and computing power.

As for why we burn up our CPUs? Again, we're human and because they're there.

Which is nice. And I have a month or so before Richard Haselgrove falls before me. (What AM I going to do to keep this megalomania in check?)

To prove I'm NOT entirely megalomaniacal, here's something possibly of interest I read on The Register today.

Hmm, we've got two 980Tis on order for my cow-orker's N-body simulations. I'd hoped to snaffle his S2070 for one of my 20-core Xeons, but he has other ideas...


One day, when I can slap 8 nVidia K80 in a box, I will.

Until I win the lottery I worked out yesterday I can probably trade up to 3 x 970 (second hand) for Outlander at little cost to me given what I could trade in for them (the Titan, the 2 x 750ti and a couple of old phones I have lying around doing nothing).

Performance-wise 3 x 970 will be only a shade more expensive (£30 or so) than 2 x 980 but quite a bit more than £30 more powerful. Looking at various benchmarks the 980 is only ~15% more powerful for a lot more than 15% of the price. [edit: Just had a look and the 970 appears to be ~150% more powerful than the 750ti, and as near as dammit comparable to the Titan with the added 'value' that now all the cards in Outlander will be the same)

I will investigate further on Saturday.

Got to love CEX!
