We're not climbing quite as fast as we did back in November, but I'm quite confident we'll be passing the Russians soon.

Time to kick some Russian Butt ! :grouphug:
... but I'm quite confident we'll be passing the Russians soon.
By my calculations, the Russians are pulling away at the moment. The gap was 11,186 when this thread started and is now 12455. :-/ :rain: :mad:
I'm giving her all she's got captain!
But seriously.. Anyone know if the linux client is gimped or something? I got 6 cores@3.5 with 8 gigs of ram on a headless linux box and this intel i use every day on windows is just killing it.

If it's an AMD six core I would expect it to get creamed by a 4.5ghz 2600k. That 2600k has way more processing power.

From my garden (http://boinc.bakerlab.org/rosetta/hosts_user.php?show_all=0&sort=expavg_credit) my 4 core Phenom II clocked at 3.5 GHz is producing just barely more than twice what a moblle Core 2 Duo (at 2.53 Ghz) makes. So clock for clock it seems that the Intel processors produce more credits. (All of mine are running Linux.)

It's not the Russians pulling away, it's us dropping off. ~2K in the last day or so.
We're definitely not supposed to be dropping off at this point.

I'm still on the rise..... Should see 2 or 3K out of me in the next week or so...

Yeah it's a amd 1090T, i didn't think the intel would be doing 2.5x more work though.. Thats a serious wooping. Guess i just thought the 1090 was better than that.

My 2600K @4.5 w/HT s getting ~5300 RAC.

My i3-550@3.8 is getting ~1700 right now, but it is still climbing .....
After 2 days my 1090@stock is already @ 800......

I wish I bought a motherboard that would overclock that 1090, but I didn't research and picked one up on a whim. Now I have to save up and get another :-(

I'll bite.. Ok, how the hell are you getting 5300RAC from one machine! My 2600k is doing about 2k now. Only been running less than a week though, usually take awhile for it to level out?

I have been running that 550 since 2/23 and its still climbing ....

You could get that out of an i7 920 or 950 Overclocked to 4.2-4.4GHz with HT enabled. I did it for a short while, but I was on air at the time, so when the weather got warm I had to idle it back.

I have hyperthreading enabled doing 4.5ghz and i aint even close to that! How long does it take for boinc to peak? Just trying to figgure out if i have something set wrong somewhere, i know with Seti you can stream line it to crunch better..
Can we do that with rosetta?

Other than making sure you have a stable overclock and enough RAM, there's not a heck of a lot you can do. I assume you're running 24/7 while CPU is use?

Yes sir, got all cores pegged 24/7.. My RAC does go up everyday, so i'm not freaking out just yet. Just new to Boinc and didnt realize it took awhile to get the flow going.

The calculation for RAC is needlessly complicated, (RAC(new) = RAC(old)*[e^(-ln(2)*t / 604800)] + (1-[e^(-ln(2)*t / 604800)])*credit(new)), but basically after ~3 weeks of crunching, your RAC should be at ~85-90% of what its max will be.
Generally what I do to calculate RAC for a new box is to look at daily average credit over a week or two, then take away ~10%. This will slightly underestimate actual RAC, but it's a nice quick guide if you're in a hurry to see how much you're doing :)

Did Rosetta change their WU's or something? It seems to me project wide that every-bodies RAC is dropping. Looking at other teams it seems that no one is safe from this?? :screwy::shrug:

Not sure what it is exactly, but production and claimed credit tend to take a nosedive accross the board from time to time.
I'm happy to report that my machine has been at 100% load for the last two days and has already regained 300pts in RAC. Hopefully my issues are over with.

There was a change in the BOINC code for how credit is claimed and granted; it was implemented in June 2010, but it still hasn't fully transitioned in yet. SETI is seeing the effects, too. In theory, assuming projects go with it, we will see *much* better device neutrality cross-projects. The goal (much like it was at the start) is to have approximately the same credit per host-hour of crunch time, averaged across all hosts. This means that some projects that are under-claiming credit will be boosted, and projects that are vastly over claiming (MilkyWay@home, mainly) should see significant decreases in RAC.
You can read about the history of the credit system, including its current implementation here. (http://boinc.berkeley.edu/trac/wiki/CreditNew) :)
