In English, Fermi = femto


LOL! The first time I see this. It looks totally ridiculous.. but apparently is true.

MrS

[OT]
it's a tribute to enrico fermi: 10^-15 m is used when measuring nuclear dimensions and so femtometers are also called as fermi.

I think your comparison to a 6.72 task was more appropriate, as they run faster, but it would have been a better reference if your card was also on XP x86 (rather than X64, which is slightly faster) and more importantly, ran at the default stock speed of 1242MHz, rather than 1.6GHz

My shaders are set to 1600, which is on the modest side of what ETA has suggested. Thought you were doing the same (per your previous posts). Core and memory are at the MSI factory set speed. The card runs cool, it's at 59C right now and 50% fan speed even though it has the OC and is the model with the single fan. Of interest: what's the Fermi temp and fan?

To clear this up: XP64 is not at all faster in GPUGRID compared to XP32, they are the same speed. They are however significantly faster than Win7 of any variety, as outlined here:

I haven't been able to pull anything since this started, betA or otherwise.

And since the apps were updated the switch below hasn't been working on any of my 5 machines. It worked before.

"If no work for selected applications is available, accept work from other applications? - yes"

The above setting is now working again. v6.72 availability seems to be spotty though.

Edit: One thing that's irritating is having to babysit the settings/clients constantly to get v6.72 WUs.

Message 16874 - Posted: 6 May 2010, 16:53:29 UTC - in response to Message 16870.  

I’m not picking up any 6.72 tasks, just 6.03, Betas and 6.73 (Fermi) tasks, can't be bothered to task babysit myself.

The Fermi seems to default to 91 deg C if you leave the fan on Auto. I would not recommend doing that!
When I had it crunching at stock I turned the fan up to 79% and the temps dropped to 82 deg C
The case was not good for cooling, and sat in a corner in a warm room!

When overclocked to 715/1430 I had to up the fan speed to 83% to keep it at 82 deg C.
I just built that system up using XP to test the Fermi actually worked properly (as it was about half speed on W7) to decide if I wanted to return it. The card is now awaiting a new computer to run in.

I also wanted stock bench marks. So I ran the first full task at stock and then ran 3 full tasks and 2 Betas at 715/1430.
So,
a GTX470 should presently get you around 59.4K credits per day on XP x86 (optimized as previously described).
and if overclocked to 715/1430 is should bring home about 66.5K

As CPU usage can be optimized so that a full core is set aside for these tasks, I would expect that an x64 operating system would have a slight edge over an x86 system.
Also, the faster the CPU, the faster the task will complete (but only by a few percent), and obviously if you use your CPU heavily elsewhere it can slow the tasks down.

When GPUGrid manages to build and test an optimized Fermi applicaiton, these figures should improve.

ftpd,
To benefit from the SWAN_SYNC=0 environmental variable, I think you also need to set Boinc to only use 7 threads (as you crunch CPU tasks as well); this will free up a CPU core/thread for use with GPUGrid. I expect this is the reason your tasks run slower than they could do. Also, you did run some Betas with no CPU usage and these were faster.

OC'ed GTX275 was really heating the room in my house this winter. I turned off heating there but it did well, saving me couple of bucks :-) I'm not kidding, it was one the hottest rooms.

My Palit GTX260sp216 uses about the same amount of electric as this GTX470, but makes more noise! It has 2 fans, which explains the noise and the lower temps. When NVidia release their stranglehold on Fermi card designs I'm sure there will be many Fermi's with non-standard heatsinks and fans. I can't imagine that the present designs are particularly good.
At least this Fermi is slightly shorter than the GTX260, does more work and is not quite as noisy.

sounds strange. mine GTX275 hardly OC'ed 702/1582?1.1V @75% fan speed gives 67 *C max, quiet often around 65. So, no doubt - GTX400 are hotter then GTX200

I found out why my SLI GTX 480s were taking on average 1100 seconds to complete the beta work units. I turned off SLI and that did the trick. My last few work units have completed in 700 seconds at stock speeds. Oddly, it still shows my gpu clock speed as .81ghz. I've noticed other users will get this to 1.4ghz or so.

when can we expect a decent pool of WUs to draw from? They seem to get pulled so fast that its impossible to continually crunch. or in my case, get a single WU. Don't mean to sound whiny, really am just curious.

If you had left them on a Win7 platform you might well have picked up Fermi tasks (even though they would have ran slowly)!
Sounds like they are trying to upload the Linux version this evening along with more tasks (presumably for Windows and Linux). Tasks should run faster on Linux than on Win7, so hopefully you will start getting through some work soon.

My guess is that it would be best to receive both Betas and normal work units. Keep an eye on what you are picking up, just in case you start picking up non-fermi tasks (which would all fail). If you do, select no new tasks from within Boinc. Then just select to pick up Betas, and not the 6.04 tasks, before re-enabling new tasks for Boinc.

Good luck,

yeah i'm currently set for beta's and acemd's only. Can't seem to pull a beta, so I'm just gonna assume everything works on my end and I just have asstastic luck with being lucky enough to get a beta unit. Tired of troubleshooting ghosts. just gonna leave this alone for the time being.

Put this Fermi (GTX470) into another system (AMD 5200+ CPU, 2GB DDR2, XP x86 SP3) basically to have a look at it compared to when it was on the faster system (faster CPU and system design, but same XP x86 sp3, driver and boinc versions). I'm expecting some differences.

Running Stock, without optimization, to begin with.
First Beta returned in 481 sec (8min):
2299002 1451202 8 May 2010 12:25:54 UTC 8 May 2010 12:36:05 UTC Completed and validated 481.17 55.67 187.28 280.92 ACEMD beta version v6.23 (cuda30)

Now running a long Fermi task.

Noticed a few things:

When running the Beta, GPU usage was 82%
Running the long 6.73 WU, GPU uses 64%

When running the Beta, CPU usage (without optimization) was 15%
When running the 6.73 WU, CPU usage is 22%

Also, this different system has better cooling:
GPU 84 deg C when running the Beta, and 83 deg C when running the 6.73 WU.
Auto Fan speed 56% and 55% respectively.



On a previous system (with a better CPU) running the GTX470 at stock, a Beta finished in 383sec (6min 25sec) when optimized (swan_sync=0, not crunching CPU tasks, report tasks immediately), for the same 280.92 credits as the above Beta.
- So it took 26% longer on the system with the slower CPU and when swan_sync=0 was not enabled;
using a faster system (CPU) and swan_sync=0 shortened return time by 26%

The current 6.73WU will tell me how much slower this live WU is when using a slower system (mainly down to CPU) and without enabling swan_sync=0.

A 6.73 WU (running at stock) finished in 17,345 sec (4h 50min) for 11,931.63 credits (suggesting 59400 credits per day).

Next, I will run the Beta and 6.73 WU's with swan_sync=0 enabled:

That will show the difference between running with swan_sync enabled and not enabled; how much faster swan_sync can make the task run and the credit difference.
It will also determine the different between running the tasks on different systems (the eight threaded system compared to this dual core AMD 5200+ CPU); the influence of the CPU.

Thank you for that info skgiven. You are really dissecting these new cards and I'm sure a lot of us new 470/480 owners appreciate. I know I certainly do.
