Paul, any chance you can reduce the size of your sig? It's a PITA when trying to read threads cause you post it every time.

Just go into your Account/Message boards and private messages/Hide signatures & put a check there and you won't see Signatures ...

I finished a WU HERE using v181.22 V-Card Driver & 6.3.21 BOINC Client on a Win XP Pro x64 Box & have several other almost done with the same setups. The Work unit took about 8-10 Minutes longer than Normal for that Type of WU running with 3 & 1 Settings.

I'm going to switch the Box to 4 & 1 & run another 6.62 on it to see if there's a difference & how much. Will report on it later this afternoon after it finishes.

Got 1 error.

OS:Vista x64
Driver: 180.48

Ohh, 6.62 is so sweet thing! Thanks to all developers!! 4-6% load on one core! At last we can crunch with pleasure! Even while gaming...

Yeah but whats your Gaming going to be like if the GPU is Crunching WU's ... ???

Yep, I've never seen Pauls sig or anyone elses :)

Last 6.61 WU (an SH2 type) on my machine with the GTX260 (192 shader) card took 6 hours 36 minutes.

First 6.62 WU - also an SH2 type has reached 35.5% in 2 hours 25 minutes. Extroplating that indicates an elapsed time of 6 hours 48 minutes is likely.

One key difference with 6.62 - I am back running in 1 plus 4 mode on this machine with just a 12 minute time penalty per GPU task compared to version 6.61.

Both runs are on Vista HP 32 bit, Boinc 6.5.0 and Nvidia drivers 178.24. No games on the machine but Firefox surfing and Outlook e-mails are still responsive unlike when I tried 6.61 in 1 plus 4 mode.

I've just got to wait now until my machine with the slower card completes its last 6.61 WU in about 15 hours.

Ah... much better. PoorBoy: thank you.

Sorry, have not the same WU name.

First 6.62-WU with WinXP/32, nVidia 181.22: 241966 - 2478 credits
- GTX 260/192 @666/1512/1150
- CPU time: 366.7031 (3+1 configuration)
- Time per step: 43.210 ms
- Approximate elapsed time for entire WU: 21605.234 s

"Old" 6.61-WU with WinXP/32, nVidia 181.20 (think so): 243068 - 2478 credits
- GTX 260/192 @666/1512/1150
- CPU time: 9720.516 (3+1 configuration)
- Time per step: 35.068 ms
- Approximate elapsed time for entire WU: 17534.094 s

No go here also. XPpro 64, GTX260 6.5.0/180.84

Try the 181.22 if they will install for you, I have Two 6.62's running @over 50% done now. The 181.22's installed on 9 XP Pro 64-Bit Box's of mine with no problems at all so they should for you too ...

That did the trick, seems to work fine with seti also. Thanks PoorBoy

Run in Linux then & you don't get any Performance loss, Oh thats right you don't do Linux :P hahahaha J/K ... ;)

Actually I do have one Linux system, and I could not get any work on that system with two different GPU cards ...

When I have had never had problems keeping the WIndows XP systems with work (since the server has been fixed) I decided to stay on Windows for now.

When I hear what are the project plans for 6.62 for sure I am leaning towards getting another 295 card to put into the i7 and that will let me bump cards down so I can put the 9800 GT into the Linux box ... at that point I can fiddle with it for a couple days to see if I can get the Linux system to download work and keep busy ...

Well, my first 6.62 has just completed 3 minutes quicker than I had calculated when I posted earlier in this thread.

Compare the CPU times, elapsed times and credits for this

my last 6.61 WU

and this

my first 6.62 WU.

Remember this 6.62 WU was running the whole 6 hours 45 minutes in 1 plus 4 mode whilst the 6.6.1 was running for its 6 hours 36 minutes in 1 plus 3 mode.

Question to the developers: What was the 6.61 code doing to use 5.5 times more CPU time for the same job type????

A poll loop ...

All it did was to to check to see if the GPU needed the next block of data.

Because of the timing of the OS, and it gets deep quickly, one of the ways to detect an idle GPU is to ask it if it is done; loop, rinse, repeat ... as fast as the CPU can make the test ...

When the program loosens the timing on the CPU it is possible that the GPU goes idle for a short time. This is why the GPU application takes a little longer running on the GPU with the decreased load on the CPU ...

This is the argument on what is the "proper" organization and CPU load ...

Question to the developers: What was the 6.61 code doing to use 5.5 times more CPU time for the same job type?

The polling loop, actively asking the GPU "are you finished yet?", like almost every other previous client.

The more interesting question would be "How is 6.62 doing it?"

Which is a question I asked ... :)

On one of my XP machines (my first 6.62 WU):

App 6.61:
J15721-SH2_US_3-4-40-SH2_US_31980000_0
Time per step: 77.946 ms
Approximate elapsed time for entire WU: 58459.452 s
Granted credit: 3718.47800925926

App 6.62:
VS20854-SH2_US_3-1-40-SH2_US_3640000_2
Time per step: 80.904 ms
Approximate elapsed time for entire WU: 60677.902 s
Granted credit: 3718.47800925926

Both were run with Realtime priority (set manually). App 6.61 used ~40% CPU (dual core), app 6.62 used between 0 to 2%. The 4% penalty is well worth the drastic reduction in CPU usage for me!

Well, one of 6.62 WUs has been finished already...

For 6.61 app there was Time per step: 43.362 ms (45-50 on average), but now - 69.198 ms.

Athlon x2 5200+, WinXP x64, 181.22, BOINC 6.5.0...

What does it mean - WU processing is 1.5 times slowly than before? Or what?

From Siberia with love!

Running 6.62 on a Q9550 w/ 2xGTX 260 Core 216's superclocked, WIN XP Pro 32bit, Nvidia drivers 180.48 successfully and getting CPU times +/- 3-4 mins per WU. Since upgrading to BOINC 6.6.3 earlier this evening I've been monitoring this box with taskmgr and the CPU utilization barely registers on these WU's. The WCC tasks are humming along nicely at 24-25% each... Amazing.

Time per GPU Grid WU step is approx. mid 30's.

-----------------------------------------

On a second box at home, Q6600 G0 @ 3.3Ghz w/ 8800GT and Nvidia 185.20 beta driver, Win XP Pro 32 Bit and BOINC 6.6.3 still chunking through 6.61 WU's is working fine.

Crunching for the benefit of humanity and in memory of my dad and other family members.
