My GPU does a 50 million step WU in slightly over 4 hours. Kibbo has 2 graphics cards similar to mine as well as a mean CPU so he's definitely racking in points fast.

Just curious, but what is Kibbo running? 5 PS3's and a tri-sli 580 setup or something? Tongue

I'm running an Intel core i7 920 overclocked to 3.8GHz and 2 Nvidia GTX 560 Ti. This picture of HFM.net illustrates what this setup is capable of. PPD is the performance measurement used for folding@home and stands for "points per day", i.e if you were to have your clients running 24/7 you would get that many points every 24 hours. In this picture the CPU PPD is a little off because I had just started it up for the day (crashed during the night, stupid first gen i7 glitches), normally it sits around 13000 PPD. The GPU client varies greatly from one project to another, as you can see Project 6805 gives roughly 3000 PPD more than a 6800.

what kind of cooling do you have on your i7. mine gets stupid hot when running the smp client

I'm using one of the earlier versions of the Thermalright Ultra120 eXtreme combined with the Scythe S-FLEX fan.

Too bad I have an ATI card (MSI R5770 Hawk which was midrange last year). f@h seems to hate them. I can't track queue data in either FahMon or HFM and I only get WUs that are worth 511 points even though i finish 5 of those per day.

I'm now convinced I'm doing something wrong even though i followed the install instructions to the letter. my smp client restarted that 2million step WU which is no longer going to finish on time and i'm supposedly only getting 937.6 ppd with an i7 930. I'm killing this one. It's a waste of time right now.

All AMD/ATI cards are unfortunately garbage at folding and generally they're able to deliver about 1/10 of the performance of nvidia cards in the same price class. There's definitely something fishy going on with your SMP client though.

Looks like I'm stuck using -smp 4, limiting the client to 50% CPU usage, for my CPU client for a while, the recent batch of SMP WUs like to make my system restart for no good reason (the f@h stability test runs fine). Not exactly a good thing if I'm not at home and can set everything up right as it happens.

Not a huge loss, really? What with HT 'cores' being 2/3 a real core, or so? But I guess this is something for us to take notice of. F@H has trouble with >4 threads? Not that that applies to many people atm, but greater then 4 core chips (consumer) are right around the corner.

Ignore the current x6 >_>

You didn't pay much attention when I told you on IRC that number of cores used is not linear in comparison to performance, did you? Tongue

Using -smp 4 instead of -smp 8 reduces SMP folding performance by about 75%, not 50% as is very easy to believe (and in many cases would make perfect sense).

Holy hell, 798! Who's this medusa guy, and what's he folding with?

Oh, I paid attention. I also mentioned this little gem: http://en.wikipedia.org/wiki/Speedup
Call me a liar caller, but thats some basic stuff you are calling wrong.

medusa is one of nate's ps3s iirc.

I'm not calling anything or guessing or making up theories. It's what actually happens on my system when I go from using 8 cores to 4 cores. Period.

going from smp 8 to smp 4 somehow made it work better for me. I am clueless on this shit. I get 1% in 15 minutes instead of an hour. Too bad its still folding a WU that was due yesterday. Shouldn't that one have died already?

Even though I've not been around for a while, I decided to put my desktop & laptop to some use and start folding for team SDA. It's been somewhere around 7 years since I've done any.

I'm working with a slightly OC'd Athlon 64 3200+ on my desktop and a Turion X2 on my laptop. I might throw my PS3 on there too for good measure.

Rank changes are slowing down quite a bit, but we just hit 777. Can we reach 750 without some new hardware? Time will tell.

I've been folding on my PS3 for Team SDA off-and-on since I got it, and recently set up the client on my desktop now that it has a decent proc (i7-860).

Waiting for my "salary" this month, will get a new chassis and watercooling for the CPU, then I turn that SMP client back on. Only GPU clients for now.

Yes, it's amazing. The system was somewhat stable before but now it's rock solid. I'm even thinking of making a new try at reaching 4GHz on the CPU overclock Grin

It's an i7 920 currently running at 3.8GHz (up from the default of 2.66GHz). All 8 virtual cores enabled.

yo me again. Recently got my PS3 and stuff set up, I've found the F@H thing in the "Life with playstation" but I can't for the life of me figure out how to change any settings that lets me contribute to a specific team and stuff.

2011-06-10 10:57:20 am

ha, of course as soon as I post saying I don't know how to do it I find it instantly. Ah well. Anyhow, so now I'll be able to use my ps3 along with a 5770 and 6850 once I get it set up on my PC again, should be fun to see.

Ah, finally they made this available for eu accounts.
I've set up my PS3 now, but there doesn't seem to be any place to enter your key for your nickname. Let's see if it makes a new or if it can actually add to the existing account despite lacking the key.
