SP / DP was to be my next question but that's been answered, so it looks like if you had the cash a Dual 18 core Xeon box with 2x Titan Z's would be the best bet?

Damn when I win the lottery I am defiantly building the worlds best home Seti box, something you can still run off the mains and use day to day I think, would be awesome getting to play with that kit and giving something back with all the power :)

You don't really need that much CPU oomph. An i5 or i7 with a pair of those GPUs would likely be in the top 15-20 computers for the project. The CPUs, in comparison to the GPUs, would only account for a small fraction of the work the machine completes.


If anyone cares to have a look at outlander, it's an i7 overclocked to 4.4GHz with 16GB RAM and 2 original TITANs (not Z or Black)

When I win the lottery I'm going to use a couple of these...

...which has done more work in a few months than every other machine I've had combined did in 14 years...


OK, I lied, I actually looked at the numbers and outlander has done a shade under half the total of all the other machines (or about 1/3 of the absolute total)

But still!

I'm a month away from having been doing this for 15 years! Only this year did I build a dedicated rig (with 2 nVidia Titans) which has done more work in a few months than every other machine I've had combined did in 14 years...

OK, I say 'dedicated' I may play the odd game on it now and then :)

And next year I'll upgrade the graphics cards again or build another machine and bump it all up again.

Fun, isn't it?

10,227,770, as of writing. 14 years crunching today! Donations all round!

[about] A year ago today I passed 1,000,000 Today, I'm a quarter of the way past 10,000,000 on my way to 11,000,000! 9 million in a year. I like that.

I wonder if I can make 100,000,000 by next year?

Oh come ON, I can dream, can't I? :)

Fair enough, and my bad for attempting to define 'official' :)

For 'official', then, read 'handed out by BOINC when you connect to the Seti@Home project servers'.

Right, here's how I understand the state of GPU crunching as it stands at the moment.

PLEASE CORRECT ME WHERE I'M WRONG!
I'll then take the corrections & other information and write it up as a blog post on my website and link through to it there. Hopefully it'll help others as the information seems to be all over the place and at least for me was a bit confusing to track down. (on less someone else has already done it in which case I'll get back in my corner :) )

1. Windows
This pretty much works 'out of the box', there are official (read; written by Seti staff) apps. BOINC will determine that a compatible GPU is available and the Seti servers will send down different apps to run work units. The servers will eventually narrow down which GPU app runs tasks fastest and send tasks just for it.

2. Linux
This pretty much works 'out of the box', there are official (read; written by Seti staff) apps. BOINC will determine that a compatible GPU is available and the Seti servers will send down different apps to run work units. The servers will eventually narrow down which GPU app runs tasks fastest and send tasks just for it.

3. Mac OS X
There are no official GPU optimised SETI apps. Try the unofficial (read; community written) version at lunatics.kwsn.net. They are for A[TI|MD] cards only and it's stated there's a bug which prevents it running on A[TI|MD] HD4xxx cards. My personal experience is that it doesn't work (fails with computation errors) on an HD5770 too.

The Lunatics also have on their site unofficial CPU and GPU optimised versions of Astropulse etc. for Nvidia and A[TI|MD] running under both Windows and Linux, though I experienced the same 'computation error' trying to run one of their CPU optimised Astropulse apps under Ubuntu.

(please don't think I'm trying to guilt or push anyone into 'fixing' things, I'm really not. I just want to understand how the lay of the land)

I find myself in an interesting situation and I will state from the outset I have made a decision and know what it is I'm going to do.

Here's the position: I find I have a couple of hundred pounds spare and I can either donate it to SETI or buy a big beefy graphics card to Do More Science™.

Now, without saying "Split it between a donation and a less powerful graphics card" what would YOU do? Donate, or Do More Science™?

Well I'm an experienced Mac user, and would love to help as much as I can. I'm in no way a coder but they give me money to pay the mortgage for my sysadmin skills!

I can test on the machines you see on my profile.

So I suppose I now have to ask: am I right in thinking that S@H only supports AMD graphics cards on the Mac or is that my imagination and NVidia are supported as well?

All those Macs and not a single MacPro. If you just had one old MacPro, you could stick a couple cheap AMD cards in it and score more RAC than your entire existing fleet...


Don't I know it! However, I Got to thinking and could do the same with the 2 XServes I have and... job done!

But it's a Windows machine, (an old HP DL320 with a raging Pentium4 inside! It's running Win server 2003) and I'm very much a Mac man and know little about Windows.

My question is: While I realise the P4 is... old - to be polite about it - if I put a decently beefy graphics card in it will that then bring it up to decent crunching performance? I'm guessing it will.

If I'm right, then I think I should ask the question that'll launch a thousand arguments: NVidia or AMD? I suppose I'll be able to drop about £200 on it and don't mind going second hand.

Thank you. Have a lovely weekend everyone!

I'll certainly have a look at it, thank you, but it's not exactly what I had in mind. I was looking for a native Mac OS X app.

Thanks, though.

Posted 30 Sep 2013 by Profile WoodgieProject donor
Look as I might I can't find any Mac OS X apps that will allow me to gracefully manage and observe over a LAN the 20(ish) machines I have running BOINC/Seti@Home.

I'm beginning to suspect this animal does not exist.

I know you can use the standard BOINC Manager to connect to other machines and while it works it's far from what I'd call graceful. Also I've not found a way to display more than one machine's details at a time. I'm thinking it'd be nice to be able to see all the machines' states in a single window.

So, does anyone know of such a beast? Or am I going to have to convince someone such an app needs to be written for the sake of humanity?

If I can be of any help I will be. I can test across 10.6 to 10.8 on a reasonable variety of Mac hardware from iMacs, Mac Minis and Laptops.

I'm not a developer, but I am a Mac SysAdmin of 20 years standing, so should be able to give you the feedback you ask for.

Please, please let me know if I can be of any use at all.

Well done Woodgie! Fly the flag my man! The extra kit with your existing 9 comp farm is gonna push the leccy bill up a bit :-))


It'd be wrong to not be concerned as all bar 1 they're at work; wouldn't it? :)

Truth is, they're all machines that are on for other reasons and SETI@Home is merely a thing they do when they're bored.

nice work and keep going

Thank you, I shall.

Hopefully in the new year I'll be adding 4 Mac Minis and a couple more iMacs to the mix.

During the recent outage the machines I run BOINC/SETI@Home on crunched their 1,000,000th Cobblestone (or whatever they want to be called)

In honour of this and as a merry Christmas to the guys I made a small donation. It's not much, but it's something.

And I've just noticed; I've been running SETI@Home in some form or another on a varying number of Macs for 13 years, today! Even more reason for celebration!

So my hat's off and I raise a glass (well, mug of coffee, it's early) to the team; Dr. David P. Anderson, Dan Werthimer, Dr. Eric Korpela, Andrew Siemion, Jeff Cobb and by no means least the tireless Matt Lebofsky who seems to do most of the heavy lifting!

Just a note:

It took me from the end of August (the 25th?) 2007 until April the first this year to get from 0-100000 cobblestones.

I went from 100001 to 200000 in 23 days!

WOO!

Didn't Astro of a while ago have a most excellent thread on his adventures with an old P90 CPU...!


Actually, it was a P60, the first generation Pentium ever released.


That would be a most worthy winner... er, I mean looser... ummmmmmm. To be frank I'm unsure what I mean but a P60? That's just BRILLIANT.

Seeing as were talking unused machines now, I DID have a Performa 400 running the old SETI@Home client back when. 16MHz of screaming Motorola 68030 POWER that was!
