bigadv worth the time??

Post by jtcdesigns » Thu Jan 28, 2010 2:58 am

So im running the latest smp client on my 8-core mac pro with 10GB ram for now. I was out of the loop for a while so I only started to do multicore a few months ago. I now run it at 8 cores using as much cpu as possible. Now I was getting around 11,000 points a day until I started to do the bigadv and im wondering is it even worth it? I know you get bonus points but.. 2.5 to 3 days for 25,000 points seems to be a bit small when I was doin atleast 10k a day. Any thoughts?

Before long the bigadv projects will be migrated from FahCore_a2 to FahCore_a3. This will improve thoughput, but I have no way of knowing by how much.

I'm not sure that understand your question about 25K vs. 10K. In any case, feel free to configure your client for whatever works best on your system.

haha yeah.. what im asking is.. bigadv really worth waiting around for almost 3 days when I can just do regular folding and get higher points per 24hour average. I just wasn't sure if maybe there was something else I can do... I'll just wait till the unit finishes in 5 hours and set it back to nonbigadv... it just seemed like a good test at first but the points dont seem to make it worth it to me. Is there an estimated time where the FahCore 3 will be out? also.. is there a tag I can put in that will make sure I get no FahCore_a1 projects?

As far as I'm concerned, yes, it is well worth it. I found doing non-bigadv A2 SMP gave me slightly lower PPD than -bigadv did before adding the bonus. The bonus has doubled my real ppd. Another thing is the bigadv uses roughly 100MB every 2days 9hours, compared with 25-50MB every hour hours... So in summary, well worth it to me.

Unless you are doing things like GPU folding (and haven't included it into your post) that complicate the situation, -bigadv should be at least worth it.

Have you completed 10 work units with a passkey, you need to do this to get the bonus...

You will reap the benefits of the bonus once you have finished the required 10 A2 units at 80% completion or greater using your passkey. My Mac Pro Dual Dual Core 3.0GHz (MacPro2,1) with 8GB RAM will complete a -bigadv unit about every 3d 1h for a nice 49,500 points and my Mac Pro Dual Quad Core 2.93GHz (MacPro4,1) with 12GB RAM will complete one every 1d 22h for a hefty 60,100 points.

wow thats a lot of points... right now I have a passkey and Folding@Home Client Version 6.26 my extra parameters are -smp 8 verosity 9 -advmethods -sendall -bigadv

Maybe im doin something wrong.. but I've let it run a couple days and still only showing that I get 25k points. What is your setup macaholic? Cause I have a mac pro from november 08 with 8 cores and the processes are showing about 98% each in activity monitor. Maybe I should let it run for a week or two straight and see if the points increase more. It shows me pts/hr is 331 and points are at 25k i dont know if that has bonus or not.

Here is the log...

I'm intrigued to know if there is anything I can do to get massive points.

Is the passkey entered in the client configuration? It needs to be.

Remove the -advmethods and -sendall flags. The -advmethods flag can conflict with the -bigadv flag. The client always tries to send any completed WUs when it's restarted, so the -sendall flag isn't needed.

It's out now, provided you install the new client. See the announcements.
Be sure you understand the new points system, too, because things will vary depending on how fast your machine is as well as what else it's used for.

also.. is there a tag I can put in that will make sure I get no FahCore_a1 projects?

No. Any SMP installation, whether it normally gets A2 or A3 WUs will get an occasional A1, depending on what the servers have available. At some point both A1 and A2 will be phased out and everything will be A3, including the bigadv.

Now there are a number of options to be compared. Today you can choose the old Windows client (which gets only A1 WUs), the old *nix client (which has gotten mostly A2 WUs with an occasional A1 WU), the new client (which gets mostly A3 WUs), or the bigadv option (which is *nix only, so it's mostly A2 WUs with an occasional A1 WU).

I know that's complicated, but my personal prediction is that within a short time, there will only be the new client and everything will be A3 and [big or not-big] will depend mostly on how much hardware you have. I'm not sure what control we'll have over the clients, but I'd expect something. I could be wrong about all of that, though.

25,000 Points is the base points value. When you complete the work unit, the bonus is applied. 8 core Macs typically get above 55,000 total points (base plus bonus) for a single work unit. Do the math, and that ends up being about double your old PPD.

To get the massive points, fold some -bigadv work units as we've been recommending for several posts now. ;)

ok.. completely psyched!! Before I ran off to work.... extremely late of course.. I shut off the folding client and whiped out the folding@home folder since it already finished the bigadv. I installed the console version which is the latest 6.29 I think? Loaded it right up and it said I should get 45000 points :D So I just did the same on my imac here at work sadly only core2duo :( and that will do 6000 points.. this of course isn't including bonus points I may get.

btw the big adv that ran did 12 WUs at home when I got up today and it showed 25,403 on folding.extremeoverclocking.com

As mentioned above, to get the bonus, the client needs to be configured with a passkey, and 10 A2 or A3 work units must be completed with that passkey in order to start receiving the bonus.

You may want to remove the -bigadv switch, and quickly finish up 10 normal a2 SMP work units with your passkey, and then switch back.

I got nice bonuses on most of my BigAdv units making them worth the time, but I intend to stop doing them as my internet connection is so slow it has taken between 4 and 36 hours to send them and think I will be better off doing smaller units, a pity as if I had been able to send them all in less than 4 hours the bonus would have been much better, at present my system completes in good time (33.4 minutes a frame) but the upload takes so long it is becoming marginal not just in points but for the project.
Should I get a better connection will definitely be switching back, even if the benefit points wise is similar these seem to be important work that not everyone can do, so if you can do them they seem like the right thing to run.

nice I have an iMac at work that I do folding so that does a couple units a day but usually I do get about 10 units when I do bigadv.. if not then I will put my imac to do normal size so I can get more units a day.. so im excited to see my performance in a week.. so far I been jumping up in ranks pretty fast. I'm not ranking at 17th when I was at 30th within months ago... it will slow down though.. I only have 440,000 points total right now.. our team isn't too big the biggest user has 3.8 million.. but I'll get there eventually.. hopefully I can fold on some of the servers at work when we replace them :D

How does the PPD compare between the SMP2 bonus WUs (FahCore_a3) and the current bigadv (FahCore_a2, at least for now)?

I haven't payed attention really to see what the points are.. I just know my ppd has been effected since I did bigadv.. but now i run my iMac at work to do regular units so I can try to keep my points perday up and my WUs
