Topic 224050

Greetings Crunchers!

I have recently changed my <app_config.xml> files for all three of my projects which I am currently running (Einstein, Milkyway, and Universe).  Since then, I am getting a message, which I don't understand, in my BOINC Manager <notices> directory which says: Missing <app_config> in app_config.xml

I have also noticed, and tried to correct, the missing preferences for Einstein but to no avail.

My current event log file begins with this:

In the user manual for BOINC, the BOINC Manager Advanced View here, there is an image from Ageless (circa 2015) of a similar event which shows in his event log the same thing, though for a different project.  (the image is down towards the end of the page)  There is no mention of the "Missing <app_config> in app_config.xml file" anywhere on the page other than the same message I received, shown in the example image of "The Notices Tab" near the top of the page.

I have checked and rechecked that the <app_config.xml> files are actually placed in their correct DataFiles>project directories for each of my projects, that they are properly named, using Windows 10 File Explorer, Notepad, MS-Word, and an XML Validation for files online.  They all check fine.

Here is a copy of Einstein@Home <app_config.xml> file for you to read.  The Milkyway and Universe files are very similar.

As for preferences for Einstein, I do have preferences set at <https://einsteinathome.org/account/prefs> for 'computing>advanced' and 'project' in the home and generic tabs, and I've compared them to one another and they are the same, to the letter.

My reasons for wanting to update/change the said files is to give some levity to each of my projects so they use BOINC in equal shares, or be much closer than they are now.  My resource shares for Einstein=150, Milkyway=45, and Universe=5, and Milkyway and Universe dominate the CPU use using all core threads available for either one one at a time while leaving Einstein on the GPUs only.

So, my question(s) are: What gives?  I'm at a loss.  Maybe, just maybe, the SETI/BOINC servers are getting backlogged too much and they're running much slower than expected, and a guy like me is to impatient too wait long enough for the servers to catch up?  And am I confused in not knowing where to find the 'host' computer?  I thought that was all settled when I configured BOINC Manager correctly.  Or did I?

Help!  :-(

You said this "I have checked and rechecked that the <app_config.xml> files are actually placed in their correct DataFiles>project directories for each of my projects, that they are properly named, using Windows 10 File Explorer, Notepad, MS-Word, and an XML Validation for files online.  They all check fine.

You CAN NOT use anything except Notepad in Windows to make and save and edit the Boinc xml files!!!!!!! If you ever open or save them with Word etc extra junk will be embedded in the files and Boinc can't then process them correctly. My suggestion is to copy and paste the files into Notepad and then same them from there in the Project folders. Be sure it saves them with the .xml as the file extension and does not add a .txt at the end after the .xml To be clear the file goes into the folder c:\program data\Boinc\projects\einstein.phys.uwm.edu folder     Just save it in the folder with all the other files, if it says it's already in there say yes to overwrite it. Then go back to the Boinc Manager and tell it to read the config files and then open the Event Log and see if everything is okay, if so you are good to go. It could come up with some unknown file application errors and that's okay as you may not have all those file applications on your computer right now, but as long as you are using the right names it will work when you do get them.

Hi Mikey!  I am not using anything but Windows Notepad, and I just looked at my event log again tonight and it is still showing "Missing..."

I'm wondering...?  Didn't I read something about Windows modifying Notepad in the last update?  It has been a mainstay for ever it seems, with no changes or modifications at all since... well, since MS-DOS?  Could that have anything to do with it?

When you posted your

When you posted your app_config file, it started with the line

[Einstein@Home]

If that's in the file, take it out. <app_config> should be the very first line in the file.

Also, when using Notepad, ensure that the file type is set to ANSI. The recent versions seem to be defaulted to UTF-8.

I have done that now.

But I want to get a clarification on something.

From https://boinc.berkeley.edu/wiki/Client_configuration:


Use the following format:

<app_config>
   [<app>
      <name>Application_Name</name>
      <max_concurrent>1</max_concurrent>
      [<report_results_immediately/>]
      [<fraction_done_exact/>]
      <gpu_versions>
          <gpu_usage>.5</gpu_usage>
          <cpu_usage>.4</cpu_usage>
      </gpu_versions>
    </app>]
   ...
   [<app_version>
       <app_name>Application_Name</app_name>
       [<plan_class>mt</plan_class>]
       [<avg_ncpus>x</avg_ncpus>]
       [<ngpus>x</ngpus>]
       [<cmdline>--nthreads 7</cmdline>]
   </app_version>]
   ...
   [<project_max_concurrent>N</project_max_concurrent>]
   [<report_results_immediately/>]
</app_config>

All the tags use lowercase characters.
Both the <name> and <app_name> containers may contain uppercase characters for the application name.

Note: The sections in square brackets '[foo/]' are optional. When you want to use any, remove the square brackets.

Each <app> element specifies parameters for a given application:


I was under the impression that when I used square brackets [Einstein] that the software (whether BOINC or MS-Notebook) would not read it.  I was unaware that <app_config> should be the very first line in the file.

Also, in the above example they use [<app> and [<app_version> with a square bracket to begin with, and  <app>] and <app_version>] to end each of the elements.  Why would they do that?  And does the software read it?

I have also changed the file parameters to ANSI.  I did not notice this before you mentioned it.

I believe the square brackets have to go away too

 

I am guessing they are using them to seperate a set of instructions from the next set, set of instructions being like:

[<report_results_immediately/>] and [<fraction_done_exact/>] but they are not consistent in the way they do it, ie the line right above what I posted is 

<max_concurrent>1</max_concurrent> with NO square brackets.

Is contained in the portion you quoted just before you asked the question:

Quote:

The brackets are a notational construct, not a specification of something to be included in the file.  The software won't read it because you will not include it in the actual file.

In programming manuals, square brackets are used to denote optional elements. They are part of the description, not part of the end product.

A comment in XML is anything between the delimiters <!-- and -->.

Once again, I thank you for responding to my questions Richard.  You are considered to be one of the most knowledgeable people in SETI/BOINC related forums and I'm happy that you even read my posts, let alone respond.
