Minor update to fix (hopefully all of) the problems with 0.80

Edit:

Another minor update for the regular 32 bit Windows application to 0.84. This is basically the same thing rebuilt so it should work on Windows 2000

Are you using app_info.xml? It looks like the same problem as this http://setiathome.berkeley.edu/forum_thread.php?id=28991#261512 if you want to try that

It's never necessary. You only really need it for setting command line arguments or excluding one version and things like that. I want actual project preferences to be a 1.0 feature so you won't need this hackery anymore.

Thanks for providing it.

Never needed one of these prior to this big event.

While I really want to avoid it, it will have to wait so I can restart the client. That is unless there is a remote way to restart it with the GPU recognized.

You don't need it unless you want to configure something

For my 5850 the estimated iteration time is now 10% too high.
Still seeing like 25% cpu (=1 core) used by system.
Without cmdline params the system is nearly not responsible.
After some testing I settled for frequency 60, polling 16, prio 1.
This way I am loosing 4 - 5% speed but the system is reacting in a reasonable time again and boinc doesn't complain about 'no response' anymore.

Estimated iteration time 177.678315 ms
Target frequency 50.000000 Hz, polling mode 10
Dividing into 8 chunks, initially sleeping for 0 ms
Integration range: { nu_steps = 640, mu_steps = 1600, r_steps = 1400 }
Using 8 chunk(s) with sizes: 192 208 192 208 192 208 192 208
Integration time = 103.704038 s, average per iteration = 162.037559 ms
Integral 0 time = 104.896748 s
Likelihood time = 2.455765 s


Estimated iteration time 177.678315 ms
Target frequency 60.000000 Hz, polling mode 16
Dividing into 10 chunks, initially sleeping for 0 ms
Integration range: { nu_steps = 640, mu_steps = 1600, r_steps = 1400 }
Using 10 chunk(s) with sizes: 160 160 160 160 160 160 160 160 160 160
Integration time = 107.757288 s, average per iteration = 168.370762 ms
Integral 0 time = 108.960545 s
Estimated iteration time 44.419579 ms
Target frequency 60.000000 Hz, polling mode 16
Dividing into 2 chunks, initially sleeping for 0 ms
Integration range: { nu_steps = 640, mu_steps = 400, r_steps = 1400 }
Using 2 chunk(s) with sizes: 192 208
Integration time = 26.706238 s, average per iteration = 41.728497 ms
Integral 1 time = 27.018571 s
Likelihood time = 2.648356 s


Are the chunk sizes calculated as multiples of 16? Another reason for those bold marked switch in chunk sizes over the iteration range?

HD4870, Win 7 64 Bit, Cat 11.5, BOINC 6.12.26, no app_info (yet). No project reset prior to the ap update. Had no problems with 0.62.

Now ps_test all fail at a little below 50% completion with a "14.06.2011 13:56:31 | Milkyway@home | Aborting task ps_test_4_991375_1: exceeded elapsed time limit 115.16 (3958564.39G/34373.05G)". And after failure they're not killed, i.e. they continue to run for some time (10 - 20s). Could be a BOINC thing - don't know, as I never had this with previous versions.
And the time estimates for these WUs were really low, like 0.01s. (would that mean I'd need to do a roject reset?)

de_separation seem to run fine :)
Well, except that they're running in high priority mode.. LOL. I've got 4 of them left, with BOINC estimating less than 10 mins crunching time for them. 8 days deadline, PC running 24/7. Still "high priority". Oh well, got to give it some time I guess.

Edit: CPU time on an i7 2600 is about half of what it used to be - very nice.

Edit2: project reset -> de_separation are not in "high priority" mode any more. Estimated time still 1s (real time ~130s).

Edit3: after finishing 1 WU the estimated time became quite close to the real one. However, the WUs are back in "high priority" mode. WTF?! I wouldn't mind this, but unfortunately it means BOINC won't get any more WUs. Last time it let MW run dry and triggered the backup project instead...

Edit4: I used to run with an app_info and a target frequency of 60 Hz. Now 30 Hz seems to be less sluggish than before and I feel less of a need for manual intervention.

Follow-up: the result duration correction factor in the client_state.xml was at approximately 100, despite the project reset. Manually set it to 1 and got rid of the high priority mode. The de_separation seem fine now, got my 12 WU cache back.

Still the same problem with and without the app_info.xml as well as multiple resets and detaches. Also rebooted the system as well. Rather disappointing that this happens!
