Message 30753 - Posted: 14 Sep 2009, 0:26:46 UTC - in response to Message 30748.  

I'm seeing close to 4 minutes on my i7 so I don't think I'll be seeing any 46 Second ones any time soon.

Don't trust the times you see in the BOINC manager. Just look to the result page (the tasks output some detailed timing) here. Furthermore, WinXP and crossfire (guess you have it activated) isn't a good combination for high performance. It works faster if you can run the cards independently using dummy plugs (or more monitors). Vista/Win7 drivers appear to handle activated crossfire more efficiently with recent driver versions.

The 4 Minutes I Quoted was the Actual Wall Time I Observed ... I don't have Crossfire Activated and have been running Dummy Plugs ever since I started running Dual Cards and the X2 Cards ... It's getting late here and I don't have time to mess with it anymore tonight. I downloaded the 6.10.30 Client and will try that tomorrow & see what I get.

PS: Is the 1 Wu Per GPU Core the Optimal way to run them or is 2 or 3 Per Core Better ??? I'm getting about 60 Seconds Wall Time now with 6.10.3 Client & only running 3 instead of 9 ...

If I install the .20 CPU app, will I be able to run the stock Cuda app along with it? The opp app stopped me from downloading Cuda WUs b4.

I reinstall 6.10.4 installed Milkyway_0.20_ATI app it is definitely faster! You are the man CP.

Also I reduced the number of cpus in the cc_config file by one, I did not think it was needed with the <coproc></coproc> statements.

It is working and fast but everything is working up to par.
Boinc downloads 48 task but only does the bottom 2 then get new ones so it stays at 48. The 3rd from the bottom start when the other 2 are reporting but never completes because when the new task are downloaded the bottom one start and the 3rd from the bottom restarts each time. I have set Milkway to no new task and it worked from the bottom up and every 4th task ran 1 second and got a error. I let them all complete then change it back to allow new task then it reported all the task and downloaded 48 more repeating what it did before. Also the status of the downloaded the 1st is ready to start and the 2nd is waiting to run(0.05CPUs + 1.00 ATI GPUs) and this repeats for all 48.
I will force the task to complete before the expire.

My site is updated as well with the new 0.20 builds for Windows.

Now we just have to wait for speedmic for new builds for Linux.

Boinc ver. 6.10.3 works just fine so far over 2 hours and no errors.

Thank you CP. Great job. Now I guess we wait and see just how much the new credits will be cut.

Speed increase just astonishing.

So let's just check what the credit reduction has done for you.

Before: 74 credits / 67 seconds = 1.10 credits per second
After: 53 credits / 46 seconds = 1.15 credits per second

Nice reduction, isn't it? :D[/quote]
Very nice Cluster Physik :D

Message 30783 - Posted: 14 Sep 2009, 8:29:26 UTC

Shut down boinc, installed 2.0 [i7 920,4870, xp home, ccc 8.12, boinc 6.4.5], started boinc, 20-something WUs [presumably left over from running 0.19f] 'waiting to run'.
Debt problems? - suspend cpdn, my cpu project. Update mw - 'internal server error'.
Someone on the board mentioned resetting mw. Reset it - 'internal server error'.
Update again - 'internal server error'. Well at least its consistent...
Shut down boinc, reinstall 0.19f. Start boinc. No reset, no update - d/l's 48 WUs and starts crunching madly.
Presumably I'm missing something...
Cheers,

I get calc errors with 9.9 driver and 6.10.4 manager,I had no errors with the 19g instead.
It crunchs correctly and then burns the next WUs,then it crunchs ok again and so on?

Well, they are 15A to begin with ...

And you cannot just swap breakers without considering the wires ... to put it another way, yes I could put in 20A breakers (still need an electrician) of I can re-purpose the 3 phase wires to single phase and if I recall correctly the wiring in that dedicated line is rated for 20A ...

Ah well, not going to happen before the end of the year ...

Even then, I will need new MB besides because all my GPU slots are full...

....

Presumably I'm missing something...

Do you have MSVC++ 2005 SP1 runtime package installed? (as mentioned in the readme.txt).

You don't need to do anything fancy with your existing cache of tasks - the app_info.xml takes care of that. I just converted 9 XP pro / HD4850 machines to the new 0.20 app and in every case the existing tasks were taken up by the new app with no problems whatsoever. However I did install the redistributable runtime package as advised and since I'm using 6.4.7/6.5.0 on the machines, I did follow the directions about removing the <coproc></coproc> stuff for older BOINCs.

Hope some of this might help - the speedup over 0.19f is really worthwhile ....

Cheers,
Gary.

Or get a completely separate 45A 3-phase mains line put in... with an extension lead to reach to your server room.
In case you didn't guess my first response wasn't at all serious.

I didn't read it this time as previous opti-installs had gone so smoothly.

Are you sure ?
Before: 74 credits / 51 seconds = 1.45 credits per second
After: 53 credits / 42 seconds = 1.26 credits per second
(depending on WUs - some 53-Credit-WUs need up to 60s some up to 30s - most need 42s)

well 1.26 is lower than 1.45 ...

I just moved most of my Box's out to the Garage a few Month's ago, my Stepson came over and we put in 10 new 20Amp Lines & Fuses inside the Garage Wall off the Main Fuse Box. The whole thing thing including time (Took about 6 Hr's) & parts cost less than $300, $200 of that I gave to my Stepson for helping out as he did most of the Wiring. He was laid off at the time and could use the money anyway ... :)
