I have just received my first AP WU's for the GTX275 on Prometheus. BOINC is initially estimating just over 17 Hours to complete an AP v7 7.00 WU with Lunatics 0.43a. (I have actually received three of these at over 17 Hours each.) Is this a very high initial estimate??? Will Prometheus complete the WU's before that time??? What should I be expecting from the GTX275 as a reasonable figure?


TL

If I remember correctly, the GTX 275 is a pretty good cruncher. It shouldn't take anywhere near 17 hours to crunch a single AP. If I remember correctly.

But it doesn't surprise me the initial estimates are high.

Prometheus Update:

FINALLY; I'm down to the last Einstein WU that was grabbed in my initial contact with the Project on this computer. I have now set SETI Main and Beta to "Resume"; and eagerly await Prometheus' crunching of SETI Main.

Prometheus grabbed MANY SETI WU's two days ago; however, I had to suspend that work while I was micro-managing the Einstein WU's. Now, I'm caught up; and, no more micro-managing Prometheus.

Beta and Einstein are both set to Resource Share of 0.1; and, SETI Main at 365. So, now SETI Main is priority one.

Thanks everyone.

As a matter of fact T.L., if I was you, as soon as I could I'd swap out that GTX275 for a GTX 750Ti. You'd get much better production while using about 30% of the power. ;-)

Cheers.

That's my plan Wiggo. It's going to take awhile on my income, though.

For air cooled, yeah that's normal, for water cooled that could be called warm... How warm I don't know off hand TL.

Thanks Vic. :-) (Yes, it's stock, air cooled; so's the GTX760.)

They're very warm buggers T.L.,so you can't compare them to the more modern day GPU's.

Update:

I've been monitoring heat and fan speed on Hardware Monitor and Precision X for the 275. Is 70 to 78 C, (with small peaks of 80 C), normal for this card??? Seems a little high with the peaks that it's getting, to me... The fan speed on it matches the temp one for one... So, at 70 C the fan is at 70%.

On Exeter, the GTX760 is at 54 C and 58% speed crunching three WU's at a time... So, I was just a little concerned about the 275 crunching only one WU at a time.

I don't think that you'll get very far trying to run 3 Einstein tasks on that card TL.

You're asking old hardware to do what it wasn't designed to do.

Cheers.

I'm NOT trying to run three; that was my Default setting when BOINC first made contact with the Project. I'm currently micromanaging the queue by having ALL but one Einstein WU run at a time; until the current queue runs dry. Then the new Einstein queue should pick up the "Work" profile settings and only run one WU at a time. The reason for the Default settings running three at a time are for Exeter; running on my GTX760.

Prometheus will end up only crunching one WU at a time on each of my three projects. I won't knowingly overtax the GTX275.


Thanks again everyone.

Einstein seems more problematic. It doesn't seem to want to come off of working three WU's at a time... It is now set to "Work", and "Work" is set to run one WU at a time; yet even after hitting Update several times it refuses to come off working three at a time. :-(

If you mean the Einstein online "GPU utilization factor" - it comes into effect only for new Downloaded tasks

Thanks BilBg. :-)

I have quite a wait then... I have almost 40 WU's to go through; and, now, currently micromanaging them to crunch one at a time... :-(

- ALF - "Find out what you don't do well ..... then don't do it!" :)
 

Based on input from Wiggo and Vic; I have just completed setting up "Work" Preferences on all three projects. I successfully changed Prometheus to "Work" on SETI Main and Einstein.

How do I change Prometheus to "Work" on SETI Beta??? I can't find a link, or anything to select Prometheus, (nor Exeter), on Beta... :-(

Make sure you go to Seti Beta where you're logged on,

so go to 'Your Account': http://setiweb.ssl.berkeley.edu/beta/home.php first, and make sure you're logged on,

Then to 'Your computers': http://setiweb.ssl.berkeley.edu/beta/hosts_user.php

Then finally to the 'Computer 73464' host details page: http://setiweb.ssl.berkeley.edu/beta/show_host_detail.php?hostid=73464,
the location preference (for that host) will be at the bottom of that page.

If you hadn't been logged on, and went to the 'Computers belonging to TimeLord04' page, http://setiweb.ssl.berkeley.edu/beta/hosts_user.php?userid=4861,
it would have been if you were looking at someone else's computers, and you wouldn't have able to see the venue/location preference.

Thanks Claggy. Prometheus is now set to "Work" on Beta.

However; for SETI Main and Beta, because Prometheus doesn't have an "app_config.xml" file telling it to crunch multiple WU's at a time, I found that it IS ONLY crunching ONE WU at a time - for Beta, it hasn't received SETI Main work, yet...

Einstein seems more problematic. It doesn't seem to want to come off of working three WU's at a time... It is now set to "Work", and "Work" is set to run one WU at a time; yet even after hitting Update several times it refuses to come off working three at a time. :-(

I think SETI wu take 250 or 300 MB video card memory. How much memory is on the GTX 275?

I see on the internetz lots of GTX 275 with 896 MB video memory. That is enough for 2 wu. 3 wu may or may not work.

Yes, my 275 has 896 MB GDDR3 RAM.

Or, does it matter???

On Exeter, in SETI's and Beta's Project Folders I have an "app_config.xml" that has Exeter set to crunch 3 WU's at a time... So, if I don't put an "app_config.xml" in Prometheus's Project Folders then Prometheus should only crunch one WU at a time for SETI Main and Beta, right???

You need to do the hard work and try it on your platform, testing is the only way to determine.

OK; now that I have this system powered up and getting ready to crunch, I need to know:

On a Pentium E5200 dual core 2.5 GHz system with 8 GB RAM, with the GTX275 on driver 266.58, will the GTX275 crunch three WU's at a time for SETI Main, Beta, and Einstein??? Or, is the GTX275 too old to do that? If it's too old for three at a time, how many WU's can be crunched at the same time?

(Will be installing BOINC 7.4.27 and Lunatics 0.43a for SETI Main.)

If it can crunch three at a time; I already have an app_config.xml that I can copy from Exeter to Prometheus. (Exeter - AMD A6, GTX760 and Prometheus - Pentium E5200, GTX275.)

Thanks again, everyone. :-)

For the GTX275 you're better off just letting it do 1 at a time with their architecture, doing more than that isn't really worth doing as they're not designed the right way for it. The Fermi based cards and their architecture are the 1's were the beginning of doing more than 1 was productive. ;-)
