A quick question about some of my tasks that are failing. I am running BOINC 6.6.36 with a Linux ptimized S@H Enhanced application V5.13; application version 5.28, and I am getting a number of workunits in the last few weeks that are getting the following stderr out

<core_client_version>6.6.36</core_client_version>

Is this a common problem during regular times and after an outage? Is there I'm assuming miscommunication/request lost when there is a lot of traffic?

Thanks.

When it asked for more work, I just got new WU until I hit my quota, and never saw those mentioned WU again. Is there a possibillity I might get them back in the future before the deadline?

And whats a ghost WU?

Thanks.

UPDATE: Everything on this page did not download to my client, however the remaining pages did all successfully download. I counted all my jobs in the manager and got around ~180 jobs, but I am missing the ones mentioned above.


Will S@H and my BOINC client eventually sync up on this, and then get my client to download them?

Thank You.

I know that this is a busy period right after the Tuesday Outage, but I decided to check in on my BOINC manager, which I rarely check, and see how well the downloads are coming. I have noticed I have a lot more results given to me on my result page on the S@H web, then my computer knows about. It says I have two astropulse units given to me, but I only received one, and there is nothing on the transfer menu and there was no results asked for during this period, and I have 19 more instances like this with the regular S@H.

Will S@H and my BOINC client eventually sync up on this, and then get my client to download them?
I'm just wondering and Thanks for your response.

I think that is exactly I used and then I got this Task ID, and In my BOINC message box said that if could not find the 'output file,' whatever that is.

But I'll copy and paste your code and download the main astropulse 4.36 file again, and I imagine I keep the same 4.35 graphics file, even if I don't look at it?

I am using the Seti@home optimized, and I need someone to re post the appinfo.xml file. I downloaded the new Astropulse Linux x86_64(4.36) and updated the appinfo.xml to match the file location for the new astropulse and updated the version number, but then when the next astropulse WU came along, Boinc trashed the one it started and all the other ones that were pending to start.

I just need someone to re post the appinfo.xml for Seti@Home optimized and for the new 4.36 astropulse for a Linux X86_64 machine.

It would be greatly appreciated.

I have a question regarding running the latest Astropulse Linux X86 when using the App Info.xml file when running the SETI@Home optimized version. I upgraded to the Linux X86 4.36 version and left the 4.35 graphics file the same (even though I never look at the graphics). I updated the AppInfo file so that BOINC could find the new main astropulse 4.36 file which I did download to the S@H work folder and this is what my appInfo HAD looked like:
<app_info>
<app>
<name>setiathome_enhanced</name>
</app>
<file_info>
<name>AK_V8_linux64_ssse3</name>
<executable/>
</file_info>
<app_version>
<app_name>setiathome_enhanced</app_name>
<version_num>528</version_num>
<file_ref>
<file_name>AK_V8_linux64_ssse3</file_name>
<main_program/>
</file_ref>
</app_version>
<app_info>
<app_info>
<app>
<name>astropulse</name>
</app>
<file_info>
<name>astropulse_4.36_x86_64-pc-linux-gnu</name>
<executable/>
</file_info>
<file_info>
<name>ap_graphics_4.35_x86_64-pc-linux-gnu</name>
<executable/>
</file_info>
<app_version>
<app_name>astropulse</app_name>
<version_num>436</version_num>
<file_ref>
<file_name>astropulse_4.36_x86_64-pc-linux-gnu</file_name>
<main_program/>
</file_ref>
<file_ref>
<file_name>ap_graphics_4.35_x86_64-pc-linux-gnu</file_name>
<open_name>graphics_app</open_name>
</file_ref>
</app_version>
</app_info>

But my question is did I do something wrong? I ask this because my task IDonly ran for one second, and then in Boinc Manager in the message box said that it could not find the output file, and then returned a computation error.

I backed everything up before I changed so I have reverted back now, so any ideas what I have done wrong or what should I do at this point, if anything?

EDIT: All the proper files like the "astropulse_4.36_x86_64-pc-linux-gnu" were all in place at the time of running.

I have a question about optimizing in Linux using the optimizer for SSSE3 Intel Processors. I have an unclocked system Linux 2.6.24-19-generic running Ubuntu 8.04 with a GenuineIntel Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz [Family 6 Model 15 Stepping 11] that is SSSE3 compliant with 1997.14 MB of RAM.

Is this system compatible with this latest optimizer? If I run SETI@Home with this system it won't burn out the CPU or anything? Is there anything else I should be concerned about this system if I do run it ?

Thanks for your time, it is really appreciated.

I just downgraded from AK_V8_SSSE3_LX64, but now when I download new tasks the BOINC manager says it takes like 11 hours to complete them, but then when it is running it drops by like 20 second increments after just one seconds. Is there a way to correct this?

I've tried detaching, deleting the BOINC folder and reinstalling, but it keeps happening.

Does anyone have any ideas?

Thanks in advance.

Hey y'all, I've just came back to boinc to crunch some more numbers for SETI@Home, after my installation, I am finding after an half hour to an hours running, the boinc setiathome child process turns into a zombie, and still takes all the cpu.

Is it still working, or is it not? Is there any way to prevent this? Thanks for all your time.

Thanks.

In the tech news, it said
July 12, 2005 - 19:30 UTC
Last night we had an extended lab-wide power outage to replace a (rather large) faulty breaker. This faulty breaker was part of the cause of two unexpected outages earlier this year. We've been told that during further examination three more potentially bad breakers were discovered. Not sure what this means exactly, except that we will eventually need another outage to fix all that. However, the nearby MSRI building (that stands for Math Sciences Research Institute, and is pronounced "misery") is wrapping up major renovation. So the lab has been planning some down-time anyway when our neighbors are added back to the grid. This may happen as soon as August.

On the way down last night, and on the way back up this morning, we reconfigured and tested our smart UPS system on the main BOINC data server (and BOINC web server). There was some weird behavior and confusion both times, but this was eventually sorted out, and now this system should safely shut down in the event of a power outage. Note that we had a work-around solution in place for months (that was also tested and proven to work), but it was not nearly as graceful as a smart UPS.


Their servers will be backed up for ~24 hours while they clear it up, also the result of everybody trying to connect at the same time.

if you are referring to attaching it in the boingmgr program, it didn't really work for me whe I updated from 4.19 to 4.43. go cd your directory you put it together/installed it in (EX. /home/you/BOINC) then "./boinc -attach_project http://setiathome.berkeley.edu ACCOUNT KEY HERE" in the terminal. be sure there is a space between the address and account key.

More info http://boinc.berkeley.edu/client_unix.php.
