Message 57690 - Posted: 28 Mar 2013, 18:08:10 UTC

We started some new runs today.

The runs are:

de_separation_82_3s_dr8_2
se_separation_82_3s_dr8_2

These will involve new star files.
Please be patient as the new star files are distributed.

Thank you,

Jeff Thompson

Message 57691 - Posted: 28 Mar 2013, 18:28:05 UTC - in response to Message 57690.  

Are these WUs much longer than the previous ones?

I'm asking because my BOINC client decided to switch to panic mode immediately after it got one of them.

Here's the WU's XML definition:

<rsc_fpops_est> is much higher than it's used to be. BOINC deducted an estimated execution time of more then 24 hours...

I have got some of them and the estimate run time is 87600 hours !!!! even CPDN tasks dont take that long.
All tasks are now running in high priority and BM will not download any new work because of the crazy high estimate run times,
The estimate 89643799999999998000000 GFLOPs for that task :()
And that is on a ATI 7970 that usualy takes about one minuet to crunch a `sep` task,
Me thinks something is wrong :)

EDIT - one of them just finished is 62 seconds as normal,
The rest sufer a Computation Error as soon as they start. Too many errors (may have bug)

Yep, there definitely is something wrong with these tasks. Mine was crashing after a split second. Here's the stderr output:

Yep, there's something wrong with those. Estimated runtime 87600 hours and error out instantly.

Interesting thing: one of my wingmen was doing such WU on ARM and could complete it in 20 seconds. The std_err output however does not look healthy.

Message 57697 - Posted: 28 Mar 2013, 20:01:44 UTC

I pulled these runs down. I think I know what the issue is - the step sizes in the volume integral were set too small, which ironically causes the server to freak out because of a fix that was implemented due to some big step sizes that made the server freak out.

We should have them repaired and back up later tonight.

Message 57699 - Posted: 28 Mar 2013, 22:12:21 UTC - in response to Message 57697.  

I have started new runs with larger step counts I am creating a new thread for these runs.


Thank you

Message 59128 - Posted: 26 Jun 2013, 23:35:08 UTC - in response to Message 57690.  

I'm getting the error that they were getting back in March now in June.

I get the following:

<search_application> milkyway_separation 1.00 Windows x86_64 double </seach_application> Unrecognized XML in project preferences: max_gfx_cpu_pct Skipping: 40 Skipping: /max_gfx_cpu_pct Unrecognized XML in project preferences: allow_non_preferred_apps S

its cut off after the S on that one.

Then another one is

<search application> milkyway_nobody 1.18 Windows x86_64 double OpenMP, Crlibm </search application> Using Open MP 1 max threads on a system with 8 processors Could not load Ktm32.dll(126): The specified module could not be found <search likelihood> -942

its cut off after that. I searched my system and I do not have a file called Ktm32.dll.

Finally I get the following:

<search application> milkyway_separaton 1.22 Windowx x86_64 double </search application> Reading preferences ended prematurely Error loading Lua script 'astronomy_parameters.txt': [strong number_parameters: 4...]:1 '<name>' expected near '4' Error rea

and it cuts off after that. I searched and I dont have a file called astronomy_parameters.txt.

I've gotten several of each type error recently. Should I be fixing something?

Thanks...

James

Since you have no errors or invalids in your results, I'd say no. Missing astronomy_parameters.txt is completely normal, the others does not look "dangerous".

I mean, it runs, that's good enough.
