If Cern does not want X86 hosts running tasks here it is as easy as not sending out tasks for X86/32bit hosts.


There are 32bit versions of Windows that are still supported by Microsoft

XP, Vista and 7 are now outside normal support, and are not recommended to be connected to the internet, as are all older versions.

What can I do on my Windows Vista 32 bit that cannot be upgraded to 64 bit. It has worked since 2011 OK for LHC@Home?

I have Rosetta working OK, for a month but even if I turn all those Rosetta off I now have a totally completed LHC@Home that has been stuck with "Ready to report" for 3 days.

In the week before that I ran 1 Rosetta and I LHC@Home both working properly.and upgrading properly.


Have you tried an Update in the last few hours ? The server side update may have fixed it for you.

There is also a workaround that has worked for some Windows users, that involves editing the ca-bundle.crt file in c:\program files\boinc directory.
Make sure that you look in the correct BOINC directory or folder, there are 2, one in Program Files, the other in Program Data.

It's not recommended to continue using older Microsoft Windows systems online unless you are aware of the security risks. It's strongly recommended to update upgrade to a newer OS version.

Two weird things:
Why was an Android Boinc issued that didn't sort it?
Why haven't LHC done what Rosetta did and sort it at their end? Rosetta now works on any Boinc version.


I'm hoping that the admins here can do that.

https://support.sectigo.com/articles/Knowledge/Sectigo-AddTrust-External-CA-Root-Expiring-May-30-2020 is the official website of the CA that owns AddTrust.
AddTrust certificates are apparently "Legacy" software, which I assume means that the company was bought by Sectigo at some point in the last 20 years.
The most recent Android BOINC updates were several months ago.

[Edit]
This page https://support.sectigo.com/Com_KnowledgeDetailPage?Id=kA03l00000117LT may also be useful to the server administrators for LHC@home

It is to STAY at the top of this thread so when ANYONE wonders why this happened they come here and fix the problem in mere minutes.

So one more try.

For Windows 10 X64 all you do is update BOINC.......no magic tricks.
Worked the same with Win 7 X64

https://boinc.berkeley.edu/download_all.php
Version 7.16.7


Suspend your work and then X-out your current version of BOINC and update to this version and reboot and all your finished tasks will go to Cern servers and leave your BOINC Manager Tasks finished page and then continue your work and they will return when finished as usual.


That's fine for 64bit Windows, but Windows is not the only operating system that has this problem.
My Windows system is working fine, but I still need to report the work on my Android system, so do many other Android users!.

Some people use other operating systems, that are not Windows !

There is apparently a BOINC Flag that can limit the number of Cores that a Project will use.
I have not managed to get it to work properly yet.
My 4 core Intel Atom machine can only manage 1 or 2 Rosetta tasks without struggling, but it also runs Einstein tasks on the GPU. It can manage 3 LHC or WCG, or 4 SETI tasks, if we ever get work from SETI again :(

Posted 1 Jun 2020 by Keith T.
Post:
This is more of a BOINC question than an LHC question.

The BOINC client software switches between tasks every 60 minutes by default, if you have more tasks In Progress than available Cores.

I have seen it try to run several tasks, but run out of memory, or disk space. It may then switch to a different task with lower expected resource usage.

The Event Log may be helpful, otherwise, you might get more information here https://boinc.berkeley.edu/forum_index.php

My phone lets me in settings disable individual certificates, so I would have thought we could just turn off the offending one, if anyone knows what it's called.

There are actually 4 expired AddTrust certificates, with names that include: Class 1, Public, Qualified, and External.
All 4 expired on 30 May 2020.


https://support.sectigo.com/articles/Knowledge/Sectigo-AddTrust-External-CA-Root-Expiring-May-30-2020 appears to be the authoritative reference from the issuer.

I have tried disabling them all, without success on 7.16.5 for Android.


That doesn't make sense. Either it's not disabling what you tell it to, or something else has expired. Or perhaps Rosetta had the option of using a different one in the list and LHC does not, so what you've done is given it no certificates to try?


I currently have 3 LHC tasks in progress, 2 are Ready to Report, about 60 hours of work. Deadline is 3 June according to the client, but 4 June on the website !

In Android 7.0 settings, Security, I have disabled the expired certificates, but I can't see any option to delete or remove.

Can I force my SSE3 capable computer to use SSE3 file using app_info.xml ?


Well I gave it a try, seems to be working so far !

Here is the app_info.xml file I created:

<app_info> 
    <app>
	<name>sixtrack</name>
            </app>
    <file_info>
        <name>sixtrack_windows_sse3</name>
        <executable/>
    </file_info>
    <app_version>
	<app_name>sixtrack</app_name>
        <version_num>44401</version_num>
        <file_ref>
	   <file_name>sixtrack_windows_sse3</file_name>
            <main_program/>
        </file_ref>
    </app_version>    
</app_info> 


My original file had [Tabs], but they have disappeared when I posted this. I think the file should still work though if you want to try it.

I downloaded the executable from http://lhcathomeclassic.cern.ch/sixtrack/download/ using Chrome, then copied the file into C:\Documents and Settings\All Users\Application Data\BOINC\projects\lhcathomeclassic.cern.ch_sixtrack

I exited BOINC, copied my app_info.xml into the same folder. Restarted BOINC, and the LHC tasks which had been downloaded for sixtrack_windows_gen started using sixtrack_windows_sse3.

Checked using Windows Task Manager that SSE3 app was running.
Also checked BOINC startup messages with:

I have used optimized apps at SETI@home and understand the basics of file editing, but I'm not 100% sure what detail to put in.

I've also manually downloaded the SSE3 and PNI files from the server, but they show as file instead of .exe

Posted 10 Jul 2012 by Keith T.
Post:
I know a million BOINC credits won't even buy a cup of coffee, but many people have wasted hundreds of hours and lost thousands of credits in the last few days.

One of my computers http://lhcathomeclassic.cern.ch/sixtrack/show_host_detail.php?hostid=9766664 had the _9 iteration of several tasks, and I thought a few hours ago that it was helping to clean out the database of zero byte files.

I didn't realize that some of those WorkUnits had previously been successfully downloaded and crunched by at least 1 host that was waiting for a validation.

e.g.
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1776621 7.3 + 3 hours
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1837803 5.3 hours
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1793416 18.4 hours
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1776892 5.99 + 5.9 hours

http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1765377 19.99 (mine) + 2.44 hours

http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=1781803 46.26 + 3.98 hours

Those 6 WUs represent over 118 hours of Crunching time. There are probably thousands more over the last few days.

I am aware that this project has adjusted credit before in exceptional cases, I hope they may consider doing it again in this case.
