Almost 3 days to complete? (if my math is right)

I might have to try this out.....

Question: You had a past problem with a unit not restarting, right? I fear that's why I loose a unit every so often (not being taken down "nicely")

yeah i think it took him about 3 days. but still, look at his points for that! over 51k! i might be trying it as well

2.9 days.

Had another power outage and the unit resumed this time.
To be honest I don't think there is any difference between these units and other SMP units as far as loosing when restarting. I have had back luck with that, less than 50% resume when stopped for any reason. This might actually is my biggest gripe with Folding... The second is not having a GPU client for macs, hopefully OpenCL will change that.

Go ahead with these big units, really worth it.

Should take more like 2.5 days then with these time frames, 29k bonus so 54k ish for the unit resulting in 21.5k PPD. Great. These Core i7 are fast 4 cores...

My router crashed when my last unit was at 89% and reset all my Folding units on all machines (this is really a stupid bug from Folding).

thanks. yeah i'm hoping to get around that. i do like this i7 machine. i just wish apple would release a desktop with one between the mac pro and mac mini. maybe one day.

dang, you lost all that work!? that's crazy. i've had a few power outages in the last 3 months. i hope something like that doesn't happen to me

Well I used this lost WU to put the machine on a 1250VA UPS and add a 2TB eSata backup drive... This is only the second time in two years the Airport Router crashes but annoying it takes my WU down on all my machines.

Looks like I could overclock the machine 10-15% for a potential 20-30% increase in PPD but the clock might be messed up.

The 2.93Ghz Nehalem can do the unit in 1.5 days for a 44k PPD... Too bad the config I need would cost $7k. The 2.6Ghz takes two days for $30k PPD... If only Apple had kept the old price points on the Mac Pros...

oh wow. i actually have my i7 overclocked a little bit.

dang, 44k and even 30k PPD is crazy. yeah if apple did keep those prices, i might have gotten one.

so far every time i have ctrl-c'ed to quit it it has reset. goes on about not being able to read the queue. overnight i had 10 frames done. there's no way i'm gonna be able to not quit these work units during the week. if that happens every time i may only be able to do one on the weekend.

considering those are worth 25K points w/o bonus 10 frames is like 2500 points down the drain. i developed another strategy, making a copy of the entire folder beforehand. i successfully transferred the work unit to another faster mac pro and started it up at 5 frames. well, maybe faster it's a 2,1 at 2x3ghz and the other was a 3,1 2x2.8GHz. most of the people at work here that have mac pros are scientists that actually use them to crunch data.

at least this way if something goes wrong i could submit it from another computer

not a bad idea. seems like more work for you though. but hey, if it works, and saves you time in the long run, then might as well do it

I'm whiterabbit

I had my G5 doing big units but I wasn't getting very many points for them so it's getting reformatted (was going to do that anyway since I have a Mac Pro now) and I will start over with it. Mac pro is doing well on SL but no open GL:( I have 8 machines now: 4 with slow AMD cpu's and Lunux, 1 with a faster AMD cpu, G5 1.6, Mac Pro '09 2x2.6 with SL and a new i7 with the 920 cpu and Linux I got an Nvidia gtx 960 hopeing gpu support might come along sometime but may have to go to wInDoWs to use the gpu:mad:

have you tried the really large point units on the mac pro?

Forget the G5...
Forget GPU on the Mac Pro and the Core i7.
Just got with bigadv units.

I lost another big one, yet another network crash... This is getting ridiculous.

this may be a lot of work (and more computer space), but you could cp -R the entire directory periodically. if it crashes, just start it up again from the backup

seems like a lot of nice machines there. how do you like the i7 so far? i really love mine

i don't know. the bigadv units will get you big points, but i'm not so sure i like doing them that much. i mean, if anything goes wrong in 3 days, you lose all that work. and i've had my system freeze up twice while doing them and still trying to use the machine at the same time.

sorry to hear that you are still having problems though.

Now you know how us mere mortals feel. My MacBook takes 2-3 days to crank out normal units.

So far so good though I should have gotten a cheap graphics card since I can't really use this effectively with linux, can't get any drivers for it:( I have an AMD Phenom 9600 x4 that seems to be doing better than the i7 920 but I haven't done any tweeking or oc to see if I can get more out of it yet.

I think I will stick with normal units for now too.

My mess is below:D

wow. an interesting setup you got there. i see the fan near, but you aren't too concerned with dust and stuff?

also, you are right with the gpu and linux. even though it is possible thru wine, it's not easy. my advice: either run windows, do the gpu folding and linux folding thru a VM, or run linux and do the bigadv units.
