Some optimistic news for Arecibo

Our staff will be working with our astronomy community to identify cost savings … (and) we are confident that Arecibo's remarkable research and educational programs will be kept strong into 2011 and beyond."

Citing Arecibo's unique strengths, Burns said he is confident that Arecibo will continue to prove its usefulness. "The refocusing of scientific programs is something we can handle very adequately," he said. "We're very optimistic for a scientifically exciting future."

help...not sure where to post.....i just installed boinc....which i really don't like but it keeps saying communication deferred...not sure if that means seti is running or not?

Your host downloaded one WU. To see if it crunching, you can open Boinc Manager, assuming you are using that configuration, and go to the tab “Tasks”. In that tab, you will be able to see what the application is doing.

For info about using Boinc, see the Owner's Manual at the Boinc Wiki.

Hi,
I know this isnt the right place for this but i dont know where is... sorry.
I changed the date on my computer by accident when using the clock as a calendar, now boinc thinks the date is 11 days ahead and wont go back to normal.
I have 3 tasks that are ready to report but its just sitting there doing nothing. The stats page has plataued at my last credit all the way up to Nov 18th.

Anyone know how to fix this and get searching for aliens agian?

Exit Boinc, bring back the date to the correct one if not done already, start Boinc again and have a look to the messages in the appropriate tab to see what happens. If needed, go to the tab “Projects” select “Seti@home” and hit the “Update” button.
Hope this helps.
25) Questions and Answers : Windows : client error (Message 452728)

When my pc run the software after doing some percent of works it finish it and when i report it to server it shows me that i had client error.i want to know how i can solve this problem?

You had on one WU following error
exit code -1073741502 (0xc0000142)

This error is, according to the Boinc Wiki, due to over stressed hardware, usually by heat or due to flaky, or bad device drivers.

Check you have the latest DirectX driver and the latest video drivers. If after upgrading these ones you still have the problem, a possible solution to avoid the problem is not using the screensaver.

I don’t have any personal experience with the Account Manager, but I guess you attached to the Seti project by using the wrong way. If you wanted to attach to the Seti project and didn’t’ used BAM or GridRepublic, you should detach and attach to the project by using the “Tools” “Attach to projct”.
I hope this will help. If not, please come back.
27) Questions and Answers : Windows : Reformatting... wish to save uncrunched WUs (Message 451307)
Posted 5 Nov 2006 by Profile Thierry Van Driessche
Post:
Thanks, Aurora.
What has happened is this:
I copied and pasted the uncrunched WUs to the BOINC\\projects\\setiathome folder, and BOINC is running well. I did get the option to merge, which I did. I copied and pasted the chicken app files there, too. BOINC recognises the chicken app, but seems to be blind to the WU files.
I have a four day cache set in prefs, but only get two WUs downloaded from Berkeley, and the WUs I copied and pasted don't show up in manager (about 10 of them)
I'd really hate to delete the WUs, unless absolutely necessary.
I'm running BOINC as a service, in XP Pro on this machine.
Any ideas?

I’m afraid that if you didn’t copy and paste the entire Boinc folder that the earlier WU’s will be lost as the information about those WU’s are stored in different xml files directly under the Boinc folder.

please help me

You are already attached to the project as you have one host attached to it. You downloaded one Wu that was interrupted in crunching as you detached from the project, which wasn't needed as normally everything should have been working fine. Apparently you attached again to the project and your host downloaded a new WU after that.

For info about using Boinc, see the Owner's Manual at the Boinc Wiki.

Hello,

I am using ZA version 6.5.737.000 (the free version) and not using a proxy.

When setting boinc.exe, boincmgr.exe and boinc.scr as trusted - I understand that is done in Program Control - is this correct?

Boinc.exe, boincmgr.exe and boinc.scr are set as trusted in hte Access category, wiht only Boinc.exe set as trusted in the Server category.

Hello,

I was referred to this thread for instructions on how to allow BOINC through the ZA firewall, on TCP port 80?

I am using ZA version 6.5.737.000 (the free version) and not using a proxy.

Thanks in advance.

Regards,

Doug

I’m using ZoneAlarm free version 6.5.737.000. No proxy.

Here are my settings:

Firewall, main: Internet zone security is high
Firewall, main: trusted zone security is medium
Zones: loopback adapter (IP address) and network card (adapter subnet) which are normally both added automatically by ZoneAlarm. No other zones added.
Program control: medium
Automatic lock: off
BOINC Client: Access Trusted & Internet - yes & yes / Server - Trusted & Internet - ask & ask
BOINC Manager: Access Trusted & Internet - yes & yes / Server - Trusted & Internet -ask & ask
BOINC Screensaver (I don’t use it): Access Trusted & Internet - yes & ask / Server - Trusted & Internet - ask & ask

I never had any problem connecting to any server of any application (participating in 6 different projects) by using these settings.
31) Questions and Answers : Wish list : QUESTION FOR SEARCHING DATA (Message 449255)
Posted 3 Nov 2006 by Profile Thierry Van Driessche
Post:
I am new to SETI. Is it possible to search through the data either while or after it has been crunched to look for specific power ranges, periods, etc? Or are we limited to viewing the data only as it is searched? Thanks

You can use SETI@home-MapView together with BoincLogX.
Mapview gives you the possibility to view a lot of details about the spikes, gaussians, triplets and pulses.
Here you can find all the add-ons for Seti/Boinc.

Hi, As per above I have the Preferences correctly set to allow Seti to only run when the system is idle, (& I don't have different settings for home / work etc) & having run the search engine on my Windows XP sytem, can't find this global_prefs.xml file anywhere. I'm going to have to kill the current task & set up BOINC to not download anymore work by the looks of it !

This post can probably help you out of the problem.

Posted 1 Nov 2006 by Profile Thierry Van Driessche
Post:
It might be interesting to look in the global_prefs.xml file to the value of
work_buf_min_days

As you reinstalled Boinc, your host is using the default value of Boinc.

The default value for the "connect to" is I believe 0.1 days. As it is known, the “general preferences” on the server at Seti doesn’t update the preferences on the host due to some bug on the server side. This means that even if the general preferences at the server is set to 10, very probably this value is not the one used by your host due to the fact you reinstalled Boinc from scratch.

If the value found in the xml file is 0.1 day, you could change that value to 10. In order to do so, quit Boinc and edit the xml file with o.a. notepad and save the file after editing.

Has Matt made any progress on the issue with recovering the old Classic password so that accounts can be merged? That reply was dated Oct 22 and I know it is only the 31st, but is there any date for resolution?
Thanks,

The special form to recover the password is not available anymore. Matt will not be able to fix it. Sorry I don't have any better news.

Post:
Raise your "connect every 'x' days" interval slightly (maybe 0.2 to start, then up by 0.1) until you've got two or three work units, and then BOINC won't need more work right away when it hits a noisy WU.

There is actually, since several days, a problem with the setting of the general preferences: when making changes to it and hitting the "Update" button of the Boinc Manager makes no changes to the host.
Admin are aware of the problem.

I'm currently using bonic version 5.4.11 running seti. Because some of my systems are not constantly on the net, is there a way to download multiply tasks for a project? I would like to pull down 5 or 10 tasks, and have the system process before uploading them. Any info would be greatly appreciated. thanks

Cache setting of WU


Caching WU’s can be done by doing the following:

--> "Your account"

--> "Preferences"

--> "General preferences"

--> "View or edit"

which brings you here

There, in "Network usage", change the "Connect to network about every xx days" to some 1 or 1.5 days. After that, in Boinc Manager, go to the tab "Projects", select Seti@Home and use the button "Update" to bring the new value over to your host. Keep an eye on the tab "Messages" after clicking the update button to be sure the new value is brought over.

By doing this, you can manage how much WU's are downloaded.

You can repeat this sequence as long as you want. Keep in mind the WU's have a deadline of 14 days in order to get credit.

I've tried this several times, and it doesn't seem to work. I keep getting a "Bad password" error for my Classic account. So I logged in using my classic account, changed the password, tried again ... still doesn't work.
So, how do I merge the two accounts? Thanks!
Steve.

On that page, in the outmost upper part you need to fill in the e-mail address of Seti Classic
and in the lower part
"... or if you've already created a SETI@home/BOINC account and want to link it to your SETI@home Classic account:"
fill in

the Email address of your existing SETI@home/BOINC account
the Account key of your SETI@home/BOINC account
and your SETI@home Classic password

and use the "link to existing account" button.

If this is not working, then some of the given info is not correct.

40) Questions and Answers : Windows : Q&A regarding cooling (Message 438718)
Posted 17 Oct 2006 by Profile Thierry Van Driessche
Post:
For those interested.

I went digging in my old Seti Classic software and still have some WU there. This is the experiment I made.

I had Seti/Boinc running for some 5 hours, shut it down for some 5 minutes and switched to Seti Classic, recorded the temperature for the time it was running, quit the software while the temperature was still recorded, switched back to Seti/Boinc and so on. The final result of the temperature for running Classic can be seen here while it was running for some 10 minutes and the final temperature for running Seti/Boinc can be seen here.

For info, I have an Intel P4 2.4GHz that is over clocked at 2.928GHz.

As can be seen on the 2 different graphs, the difference in temperature is only some 3 degree C or 5 degree F. And also the temperature as measured is fully acceptable. BTW, the room temperature was some 20 degree C or 68 degree F.

What is important:
1. Check the cooling capacity of your heat sink and fan, which can be done by using a temperature controller software which can be downloaded at several websites. This will give you the info what is the temperature without using Boinc and while using it.
2. If there is any abnormal heating when running Boinc, check some points like the following
3. Check if the heat sink is well attached to the CPU
4. Check dust on the heat sink as well as on the fan of it. If present, blow it away or clean it accordingly. Cleaning dust from there can lower the temperature several degrees, especially on a PC where the heat sink has never be cleaned
5. Leave room around the case in order to evacuate the heat properly
6. If needed place a fan that blows air inside the case and one that sucks the air outside, which is what I am using.

It is also known that laptops have less efficient cooling compared to desktops.
