Hi

I am running an application throught the wrapper class which receives two images and outputs one image + a text file.
Now the client downloads the wu's and processes them and I know that the processing is successfull since I also write a log file to the c:/ drive on the client computer. However the results are not passed back to the server and I get this error on the client messages screen:

8/21/2008 2:56:02 PM|test_proj1|Starting uc_1219319569_46_1

8/21/2008 2:56:02 PM|test_proj1|Starting task uc_1219319569_46_1 using mdetect2 version 601

8/21/2008 2:56:06 PM|test_proj1|Output file logfile.txt for task uc_1219319569_46_1 absent

I guess this must be an error with my results template file however my template seems fine to me :

<file_info>
    <name>resIm.jpg</name>
    <generated_locally/>
    <upload_when_present/>
    <max_nbytes>5000000</max_nbytes>
    <url><UPLOAD_URL/></url>
</file_info>
<file_info>
    <name>logfile.txt</name>
    <generated_locally/>
    <upload_when_present/>
    <max_nbytes>5000000</max_nbytes>
    <url><UPLOAD_URL/></url>
</file_info>
<result>
    <file_ref>
        <file_name>resIm.jpg</file_name>
        <open_name>resIm.jpg</open_name>
    </file_ref>
    <file_ref>
        <file_name>logfile.txt</file_name>
        <open_name>logfile.txt</open_name>
    </file_ref>
</result>

I have also tried using the line <file_name><OUTPUT_0/></file_name>

but that doesn't help matters.

Can anyone see where I've gone wrong?

Thanks

Try <file><OUTPUT_0/></file> on the leading <file_info> block as well. They have to match.

Here is a result template for the sample app 'concat', which I gather is similar to yours (takes in two files, outputs one).

<file_info>
    <name><OUTFILE_0/></name>
    <generated_locally/>
    <upload_when_present/>
    <max_nbytes>32768</max_nbytes>
    <url><UPLOAD_URL/></url>
</file_info>

<result>
    <file_ref>
        <file_name><OUTFILE_0/></file_name>
        <open_name> outfile </open_name>
    </file_ref>
</result>

I tried that but I still have the same problem. Only now instead of the error message:
8/21/2008 2:56:06 PM|test_proj1|Output file logfile.txt for task uc_1219319569_46_1 absent

I get the message:
8/21/2008 2:56:06 PM|test_proj1|Output file uc_1219319569_46_1_1 for task uc_1219319569_46_1 absent

any other ideas?

My guess is that because this is a wrapper app you need to add <copy_file/> to the <file_ref> block. Otherwise, BOINC tries to use it's own flavor of soft link, but the app will just write over that, and the file will not make its way home.

See the Example section of the WrapperApp page in the Trac wiki, esp. the sample result template.

Other things to check are on the server:


* Check that the upload area, and subdirectories, are writable by the web server.

* Turn off the file deleter (in config.xml) so that you can see the files being uploaded (if they are).

* Check the logs of the file uploader and the file deleter.

Thanks so much!
the <copy_file/> did the trick, all systems go now

I am testing concat and looking for the templates files. This one really helps!
Could you give me a sample for the wu_template? It seems we need 2 input files there.

I have also tried using the line <file_name><OUTPUT_0/></file_name>

but that doesn't help matters.

Here is the workunit template for 'concat':

  <file_ref>
     <file_number>1</file_number>
     <open_name>infile1</open_name>

  <app>          concat                             </app>
  <command_line> -run_slow infile0 infile1 outfile  </command_line>
