Might it be somehow related to this post?

I was wondering why my RAC was higher than normal.

OK, shall have a look-see and post anything interesting I find for no reason other than I like the sound of my own voi... keyboard clicking.

Here is a photo of the machine reportedly responsible.

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!

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.
5) Message boards : Number crunching : Why even do this? (Message 1723528)
Posted 8 Sep 2015 by Profile WoodgieProject donor
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.

Only 15TB? Try 32TB!

Well, OK, it's only a Mac Pro connected to a NetApp SAN, but I have to beat you in something, right? :-)

Matt Lebofsky et al. you do outstanding work keeping the project going when things insist on falling over. You are adept at finding out why and picking them up again. Without you the project would have evaporated long ago.

Your work is appreciated and as one SysAdmin to others, I feel your pain :)

To others out there who work as SysAdmins and the like, the same.

Not on cross-project stats, he doesn't! :P


Holy..!

BOINC combined : 660,296,907.84

SIX HUNDRED AND SIXTY MILLION, TWO HUNDRED AND NINETY SIX MILLION NINE HUNDRED AND SEVEN (point eight four)?

That's, what, nine times my 75(ish) million cross project? Nope. Nope. Nope.

Lottery win needed :)

I just noticed I've broken the top 300 worldwide. 298th as of writing.

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!

Loving that Outlander machine. How well does your Titan run Seti tasks? I was looking into used Titans, and Titan Blacks for the double precision for other projects.


Originally I had 2, but burned one out and was getting a RAC of about 55k. Now with the Titan and 2 750ti I'm getting a RAC of about 46k

They're definitely worth it, but a 780ti works better I believe and would be cheaper than even a second hand Titan.

And then when you really get down to it a 980ti spanks the both of them, so...

Having said that, if you can get a Titan for a good price (I got mine effectively for free) then they're certainly built for it!

...and I'm hot on your tail with only 3 machines running


I have to say, my long term goal is to build more machines with multi-GPUs as opposed to using Macs I find lying about. Altogether a better idea. That way everything wins.

I say "I don't do it for the credit, I do it for the science." but that's not strictly true for any of us, is it? :)

At least LHC is up and running again, so my friends at IC high energy physics have moved their farm back to CMS simulation and analysis now. A few months ago their RAC was over a million!


That's not even fair. I could build machines like that but I want to stay married and have a home to live in :)

Here are some pictures, for them what care, of my current crop.

Right then, here's mine:




Well, one of them. Here are (some) of the others.

Some Mac Pros


iMacs and a couple more Mac Pros


2 venerable Xserves and 4 new Mac Minis (including the split personality machine, Pluto


A stack of older Mac Minis


And of course, the machine I'm posting this on, my 27" iMac. Yes, I have 2 screens attached to it, I'm a showoff, obviously :)


I have a couple more at home, Just an old and a new iMac. Machines come and go as I need to let users have desktops, but I usually have a few iMacs sitting around donating cores to the cause.

In terms of Credit I am 99th. In terms of RAC I'm 34th. I only run 6 machines, and 2 of those are helping others.

Well done to you though, but you do have 37 machines :-)))


Just had a look at where I am in RAC. According to BOINCStats I'm second in the UK (and 34th worldwide, how meta!)

OK, I can live with that!

Yeah, you gots a couple of ciphers that you'll quickly dispatch, and then Richard next month. Gets a bit harder after that...
Anyway, congrats. I guess there has to be something that Macs are good for!

I can dream, can't I? Also; SHOTS FIRED! :)


37 machines !!!!! wow you also got a power station plugged into the house as it sounds like you need one

35, one got put back to being a user's machine and the other is a split personality.

I suppose a few pictures would be in order. When I get a few minutes I might post some in that thread. (Then you'll see why power/cooling isn't much of a concern :) )
