Lazy questions

Guys I'm feeling lazy and I know you know the answers so I'm just going to post here

Should I move to Bigadv - is the ppd higher than smp2/a3? I suppose this depends on the cpu and if its on constantly?

CPUs: Phenom 955 on 24/7 (3.2GHz, stock - haven't got round to clocking it yet), i7 920 @ 3.8GHz on 6 hrs a day, E5200 @ 3.1GHz on about 14/15 hrs a day and a T7250 @ 2GHz (stock) on 24/7

and for smp2/a3 should I still be using my passkey?

i7 is the only CPU that is capable of doing it within the time required you might be able to do it @3.8 but i never got around to running it so don't know.

you wont pickup bigadv without a system that reports as having 8CPU's

And you won't complete them with being on only 6 hours/day

Stick to A3

-bigadv WUs take about 2 days straight to crunch on an i7... and the deadlines aren't much longer! 6 hours a day isn't gonna cut it unless you have a Cray lying around

so if I switch my i7 on 24/7 I should b able to complete bigadv units

is the ppd worth it over a3

Can't comment on i7's myself but my dual X5450 running A3's gets 16-18k PPD and bigadv gets 25k. An i7 at 3.8Ghz should get about the same I think.

I'll have to try a bigadv on my i7 at the weekend and see how it goes

Probably slightly lower. I get roughly that on mine @ 4.4 (7 cores, as that gives me better PPD than 8, possibly because of also running GPU clients)

Clarification: I'm talking about my A3 PPD compared to Senture's A3 PPD

Is that native or virtualized bigadv units?

How are the AMD chips getting on with crunching these bigadv's. Or is it only the i7 chips that can do them.

Oh....any ideas on when the new Nvidia cards can start crunching.

Neither

Native A3 units on Windows 7.

Ahh, didn't realise you were on about A3 units

1. bigadv's can only be downloaded and run on machines with 8 CPU's so for AMD you would have to have two quad core Opterons in a dual CPU mobo.

2. When Stanford are ready I imagine. Or Nvidia finish coding it, or when Stanford have had enough of a bribe from Nvidia to bother

Ahh, didn't notice you'd also posted your -bigadv PPD

Anyone got the answer to this one?

Marine Iguana · 21 May 2010 at 07:37

Yes you should
