Hey all, I'm back folding again... can't guarantee much time on the forums, as work keeps me pretty busy and all that, but I've started up my clients.

Running on my Q6600 (SMP Windows client) and my new GTX460. So far it looks like I'll be pretty productive!

Looks like I can expect about 13-14k ppd from this rig--not bad.
And thanks for the :beer:

So here's a question-- my laptop is an i5 M540 (2.5GHz) and it has a GeForce NVS 3100M (about equivalent to a 9800GT, I believe).
If I folded only at night, say, from 20:00 to 07:00 every day (plus almost 24/7 on weekends when I'm not working), would I be meeting WU deadlines?

And, the usual question... will I be needing to ask my company for a new laptop much much sooner if I do this?

Welcome back. On your laptop, as it won't crunch BigAdv, you should be OK on the deadlines. Classic and SMP deadlines are much looser than BigAdv.

As this sounds like your work laptop, you need to obtain explicit written permission from your employer to use this laptop for folding.

Folding on your work laptop will shorten it's life, however; it probably won't shorten it beyond the usual life cycle that most companies employ. Ergo, while it may make it only last six years versus eight years, most employers will have a computer hardware refresh cycle prior to that deadline.

Not sure if it'd be worth (assuming you can) folding on that GPU. One of the FAH experts would have to answer that one.

I've done a lot of folding on laptops and about the only thing I ever wore out was the cpu fan. You do have to avoid blocking the air intakes, as in avoid setting it on a bed or a pillow.

It would be best to fold classic WUs + gpu if you're not going to run 24/7. It won't be particularly rewarding on the cpu, but if the gpu is truly the equivalent of a 96 sp 9800GT, you should make about 4000 ppd on it, while it's running.

Unfortunately, it's just too much of a hassle. Same thing I encountered last time I tried to fold on a lappy.

Oh well, I'm doing 12k ppd minimum on my Q6600 and GTX460.

I'm not sure how you have your Q6600 set up but a decently clocked 460 should be able to put up 12000-16000 PPD on it's own. (Depending on wu)

Is_907 · Mar 19, 2011

Yeah, I'm up to ~12.4k ppd on the 460... I think it was just the WU I had yesterday.
Looks like stuff from P6800 (1298pts) are harder on my GPU than the P10936's.

24,006 ppd. Maybe we can help squeeze a little more out of that rig of yours?

@ChasR I'm up for it... oddly, when I run the SMP client as a service it puts barely a 50% load on each core.
However, when I run it from a command prompt it uses 100% on each core, assuming the system is idle.
Strange. I don't mind launching manually every time I guess...

Last time I folded full time (Fall of '08, Spring of '09), I ran two Debian VMs and got a decent boost of performance. Is that still a recommendation?

I'm hitting 57 C on core 0 and anywhere from 48 to 53 on the other cores right now, so I'm sure I could stand to push this thing to 3.0GHz at least.

ChasR · Mar 19, 2011

A single VM is the way to go now. I'm running Ubuntu 10.10 with the Linux-ck kernel.

Something is wrong in your service setup if it doesn't push the cpu to 100%.

Try removing the affinity lock from the gpu and see if SMP performance improves. If removal of the lock doesn't cause the gpu to run across all cores, enter the environment variable NV_FAH_CPU_AFFINITY with a value of 15. GPU priority should be low (slightly higher in systray)
