Message 27511 - Posted: 17 Sep 2004, 23:47:50 UTC

I just upgraded one of my machines to 4.09. The times to completion have all gone up again. Since they have never been accurate, I'm not worried about it. Now they are all reporting at least double the time it normally takes for me to complete a work unit. Seti work units say 8 hours when they only take four, and LHC work units are saying 14 hours when they only take 7. Climate prediction added another 200+ hours to the total, but according to my math it will be finished in about half the time. Also the benchmark for the machine did go down.

I think the client needs some work on benchmarking the machine it is running on.

Otherwise everything continues to work flawlessly for me.

Now that 4.09 is public, is there any advantage to upgrading on XP machines?

My times just dropped back to a normal figure, so BOINC reset the time when it changes to the next unit to process........
My name is Pascal and this message has my approval...

It is 10 oclock, do you know what your WUWUs are doing tonight...

Well said!
Been running 4.09 on my home CPU (hal) for a couple hours or so myself. Sweet release. The other posts are correct. Hardly any ffreezzzee. Impressive for this(circa 1999)PII Win98 box.
Thank you Alpha Team. Thank you Rom and da boys.
Now maybe it's time to celebrate! And after that, time to tweak.

4.08 worked well for me - resource sharing worked as expected for the first time, after being all messed up in all previous releases

tried 4.09 for about half a day - didn't have any problem other than resource sharing no longer works. I checked the debt values in the client_state.xml file and there didn't seem to be any rational for how the value was set, and as a result resource sharing did not work as expected.

will stick with 4.08 for the meantime.

regards

If it ain't broke, don't fix it.
But if your environment is similar to mine, you will want to update.

Well I'm sure sooner or later we all are going to have to update to it because of the difference in Benchmark scores between the different versions. It has to mess up the Credits some how by the drop in score I would think.

Yup.
But i am anticipating further builds. This thing is gonna be refined. If no probs, you can wait for the next build if you choose.

The version of the core BOINC Manager application doesn't have anything to do with how fast your system will crunch a work unit. The application that does the actual crunching, in this case setiathome_4.03_windows_intelx86.exe determines how fast a WU is completed. If you've turned off the graphical portion, then yes that would speed it up. Anything else your system does that uses the CPU will slow down the processing of WU's.

The work units that finish really quick I think are determined to have so much interference or bad data in them that it gives up on it quickly and moves on towards the next one.

I upgraded one pc to 4.09 running under Win XP SP2.
It works ok, but the completion time went from 5:01 to 6:12,
while all of the wus finished at about 3:30.

BTW its a P IV 2.8 HT running at 3.08 GHz.

The benchmark went from 1542/2149 down to 1251/2196 MIPS.

So it means the claimed credit will go down, too. =:-(


Can I switch back from 4.09 to 4.05 again? Or will my downloaded
wus vanish ??

Yes you can switch back to the v4.05 if you want to. I did that on 4 PC's with no problems or loss of work units or work done already. Once you switch back it will automatically re-benchmark your PC again...

I don't think they will vanish.

My machine crashed this morning using 4.05 with windows XP SP2. I removed 4.05 and installed 4.09. When it started up it still showed most of the same work units I had before. Some disappeared but they may have been missing files and the reason it locked up my machine in the first place.

I would sure make sure everything is reported that was complete though.

Ok, no problem.

Installed 4.05 over 4.09 and everything is fine.
The old amount of benchmark comes back again.

So can anybody tell me why the benchmark under 4.09
is so different? Debug Code?

CCv4.09 had a bug fix that stopped the compiler from optimizing out parts of the benchmark code.

I believe I will be sticking with v4.05 for the time being. Until I see definitive proof that the dial-up modem problem has been fixed, I will just continue to use my work around: Disable network connection and crunch the heck out of my WUs.

I would also like to see the enable/disable network connection option worked on. I would like to see the network connection still disabled when I re-start BOINC (for whatever reason) or for starting up my PC (after not running it when the weather is too hot to crunch WUs).

Other than the above mentioned problems, BOINC v4.05 works very well for me and is here to stay, unless there's a major upgrade required.

Question: Updating from 4.05 to 4.09 after the install is completed, it is NOT required to do a "Reset" this time since both cores are in the same family i.e. "4.x"?

I ask just to be sure and remembering we DID have to do a Reset when we moved from 3.20 to 4.05.


Thanks,


Dusty

I just shut BOINC down, installed the V4.09 over the V4.05 (Windows) and plain copied the V4.09 Binary over the existing V4.05 one (Linux).

In both cases, after launching the Client again, it stated something like "Upgrade detected V4.05 - V4.09", it initiated a fresh benchmark run, and then happily continued work, where the V4.05 left before shutdown.

No Project Reset or any other manual intervention required, and no Problems observed :)
