Below are some quick stats for Bulldozer ([email protected]) running Rosetta, for curiosities sake. Any questions feel free to ask.

I know little about Rosetta unfortunately, I mainly crunch for our FAH team. Someone had asked how an X8 Bulldozer was for Rosetta compared to an X6 Thuban. My rough estimate suggests ~4500 RAC for an X8 Bulldozer @ 4.0Ghz (8units/day/core X 8 cores X ~70 credits/unit), without running it for a ~month I can't be sure though.

The 4.0Ghz was achieved at stock voltage, it could be pushed further, however this way my system stays ~225W with processor at full load.

I'll thank the OP for posting this as well.

I've taken a second look at it and will make the following observations.

The claimed vs. granted credit seems to be closer than claimed vs. granted for my Phenom II x4 820 (running at 2.8 GHz.) This contrasts markedly with the results I get on an Atom which is granted nearly double the claimed credit (pushing it from single digits/task well into double digits. :D )

More interesting yet is that I'm getting about 80 points of credit granted for each WU. This is probably helped by the fact that I'm only running 3 of 4 cores on Rosetta, leaving the 4th core free for all of the other stuff going on on this PC. The other factor may be that throughput for the shared cores in BD are not as effective for this stuff as the more independent cores in the Phenom.

Overall I'm a bit over 1800 RAC on three cores which puts the per core RAC in about the same neighborhood as BD. I would have thought it would do better.

I will note the screenshots were taken with no usage of the computer whatsoever, 100% Rosetta for the duration it ran (or a close to as Windows allows).
 
sorry if this necropost, but just wanted to throw in that Rosetta has been on a bit of a "credit slump" for the past month or so. Many of my machines that haven't been changed configuration wise have seen RAC fall gradually the past few months.

However it's been picking up recently, I guess it's just a result of the usual Rosetta "New Year's workunit shortage" and odd mix of Rosetta Work (there have been quite a few "bad units" as they shake out new work batches).

sorry :blah: The takeaway is that your RAC might be understated =)

I'm impressed at the numbers you're getting, looks like BullDozer is good with Rosetta. (Still hoping AMD can pull off another "Thoroughbred B moment" with PileDriver though).

Psykoikonov, could you post a link to the machine hostid on rosetta? I'd love to see how it evens out over the next few months. i.e: http://boinc.bakerlab.org/rosetta/results.php?hostid=1260152

HankB was asking for a comparison, here's a nasty dump of a i7-930 at 4Ghz (sorry about the nasty lack of formatting)

so BD is looking good looking at granted credit :thup:
 
Psykoikonov, could you post a link to the machine hostid on rosetta? I'd love to see how it evens out over the next few months.

The machine is not crunching Rosetta, I did some work units because someone asked in another thread how BD is on the project. I'm interested to know how what wattage your i7 pulls from the wall when crunching at 4Ghz.
 
Unfortunately I don't have a Kill-A-Watt handy. I suspect maybe 200w and some change at the wall for the entire system, but that's purely a guess. Efficiency wise it's probably pretty horrible, but since this is also my main gaming rig I'm not that focused on that for this computer.

I just switch a few more incandescent lights in my home to compact fluorescent to "justify" my computer heater :sn::chair:

I've been thinking of getting another meter anyway, if I can swing it this paycheck I'll post the numbers here.

Added: wow, my tax refund came in earlier than expected, time to start looking at "electricity usage monitors" =D

Finally got some other financial obligations out of the way. Time for me to get a meter :D

Anyone have recommendations one to get? The Kill A Watt P4400 seems pretty common (and cheap), but I figured I'd get some input in case there is one for a little more that "is awesome, get it."

I guess I'm wondering if it's worth it to get a P4460 or a different brand I haven't found yet.

Otherwise I'll pick one up and get some results back here.
 
I have a P4400. The only thing I don't like about it is that it is in line. It would be cool to have something that clamps on the line cord so you don't have to shut down and unplug equipment to use, but I don't see anything like that on Amazon. (IOW not available at consumer prices.) Looks like the P4600 includes forecasts as well as measurement. I was only interested in instantaneous readings.
 
:p

Delivery estimate: Mar. 9, 2012 - Mar. 14, 2012
1 "P3 International P4400 Kill A Watt Electricity Usage Monitor"

Also, so I feel like I've hi-jacked this thread :( Anyone else with BullDozers on Rosetta willing to post here??? BD seriously looks pretty good at crunching Rosetta - I'm really wanting to build some BD boxes for friends since "gaming" and "web surfing performance" is covered, with the bonus that Rosetta crunching is good.

I want to throw AMD some bones. I mean, my avatar - the heatspreader looks like crap because it was a retail box K6-III and they epoxyed (!!!) the damn heatsink on. I bought it new, Runs 504Mhz good too... replaced by K6-III+ :D :blah:

ANYHOW, yes I can find BullDozer chips in the stats of course, but there's no direct way to determine at what clock speed they are running. You can guess by how they score on the "Measured floating point speed" and "Measured integer speed" but you still need some known machines to scale the reference.

So yea, if you have one, post some numbers please!

EDIT: ARRRGHH

Estimate Delivery Date: 03/13/2012 ~ 03/18/2012
Shipping method: USPS 1ST Class

It wouldn't be so bad, but I happened to get an i7-970 for a good price in the last few days, and I'm dying to put it in.

I was running Rosetta on my MC 6128'[email protected] for burn in. I didn't really keep track. It only ever ran 11 instances on the 32 cores. I was wondering if there was a limit to how many cores or instances BOINC can run. I expected it to run 31 or 32.

EDIT: A search tells me it should have used all the cores in Linux..maybe I had something set wrong? I did check.

any way its on fah now...Though that has freed an I7 950 for our Rosetta Team.:thup:

So apparently the seller email was a bit pessimistic on delivery time, as the meter showed up yesterday :rolleyes:

And... lawlz. My "guesstimate" of 200w?... not even close :facepalm:

Boot ~230w
Idle at desktop ~ 220w
Load ~ 390w
Load while sitting in Markarth in Skyrim ~ 495w
video card is a Radeon 6950 2Gb...

needless to say, bulldozer is probably gonna be more power efficient than that :popcorn:

I'm really surprised the power usage is that high, currently SMP folding (GPU idle) at 4.1Ghz is <250W with everything in sig (tower and router, monitor off).
 
Well, this machine might also be a pretty pathological case too. Gigabyte GA-X58A-UD3R (rev. 1.0)... which with me being lazy and leaving many things on Auto gets pretty volt happy.

Also the Radeon 6950... is shader unlocked and set to 935/1275. Might also not be so idle friendly.

Plus the i7-930 isn't the best overclocker and/or I suck at overclocking it (which very well could be, note Auto settings above) so it's not exactly a cool runner.

My Vcore (1.46v) and VTT (1.56v) voltages are basically set to "euthanize" after trying for about a month to lower them. I gave up, but the chip saunters on :thup:

Running 24Gb @ 1600 probably doesn't help with VTT either (it was on sale, honest!)
 
mbers you're getting, looks like BullDozer is good with Rosetta. (Still hoping AMD can pull off another "Thoroughbred B moment" with PileDriver though).

I suspect better than Thoroughbred B. Claimed 10-15% IPC improvement, + 10% drop in power due to use of a resonant clock mesh, expecting to clock at 4+ GHz.
