the <copy_file/> did the trick, all systems go now

Posted 21 Aug 2008 by Aharon Levine 		Thanks

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?

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|Computation for task uc_1219319569_46_1 finished

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

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

Posted 21 Aug 2008 by Aharon Levine 		Ok ,problem solved,
I just had to set ninfiles to 2 instead of 1, in

return create_work(
wu,
wu_template,
"templates/worker_result",
"../templates/worker_result",
infiles,
1,
config
);

Posted 18 Aug 2008 by Aharon Levine 		Hi
I have an application which receives two images and outputs one image.

When I try running my project with the sample_work_generator deamon (which I have modified)
The the deamon generates two work unit folders in my project dowmload folder, each one of these folders holds only one of the two images I need to send to the app.
Also in the sample_work_generator log file I get this error:
Too few input files given; need at least 2

Here is the function I use in sample_work_generator:
int make_job() {
    DB_WORKUNIT wu;
    char name[256], path[256];
    const char* infiles[2];
    const char* commandLineArgs[2];
    int retval;

    // make a unique name (for the job and its input file)
    //
    sprintf(name, "uc_%d_%d", start_time, seqno++);

    retval = config.download_path("im1.jpg", path);
    copyImageFile("../image_buffer/im1.jpg",myPath1);

    retval = config.download_path("im2.jpg", path);
    copyImageFile("../image_buffer/im2.jpg",myPath2);

    if (retval) return retval;

    // Fill in the job parameters
    //
    wu.clear();
    wu.appid = app.id;
    strcpy(wu.name, name);
    wu.rsc_fpops_est = 1e12;
    wu.rsc_fpops_bound = 1e14;
    wu.rsc_memory_bound = 1e8;
    wu.rsc_disk_bound = 1e8;
    wu.delay_bound = 86400;
    wu.min_quorum = REPLICATION_FACTOR;
    wu.target_nresults = REPLICATION_FACTOR;
    wu.max_error_results = REPLICATION_FACTOR*4;
    wu.max_total_results = REPLICATION_FACTOR*8;
    wu.max_success_results = REPLICATION_FACTOR*4;
    infiles[0] = "im1.jpg";
    infiles[1] = "im2.jpg";
    //commandLineArgs[0] = im1;
    //commandLineArgs[1];

    // Register the job with BOINC
    //
    return create_work(
        wu,
        wu_template,
        "templates/worker_result",
        "../templates/worker_result",
        infiles,
        1,
        config
    );
}


could somebody please help me with this, I've racking my brains for hours!
thanks
Aharon
