BOINC LCS 3.0 Beta
I was testing out the BOINC LCS 3.0 Beta (demo here), as I currently have 5 machines working on the SETI@HOME project and thought it might be nice to be able to put online a quick overview of what the machines in my house are working on at any given moment. I found that with my multi-processor machines (one of which is a dual Xeon proc with hyperthreading, which equates to 4 processors as far as BOINC is concerned!) the program was only showing the first of the workunits that the machine was working on. After a quick delve into the code, I found that the problem was that once the correct info had been read from client_state.xml, the array that was produced wasn't being read properly. The offending code was:
<?php
if(is_object($elements->active_task_set)) {
foreach($elements->active_task_set as $task) {
?>
<tr>
<td>Project URL</td>
<td><a href="<?php echo $task->active_task->project_master_url; ?>"><?php echo $task->active_task->project_master_url; ?></a></td>
</tr>
<tr>
<td>Result Name</td>
<td><?php echo $task->active_task->result_name; ?></td>
</tr>
<tr>
<td>Work done</td>
<td><?php echo bcmul($task->active_task->fraction_done,100,2); ?> %</td>
</tr>
<tr class="noh">
<td></td>
<td><div class="fractioncontainer"><div class="fractiondone" style="width:<?php echo bcmul($task->active_task->fraction_done,100,0); ?>%;"></div></div></td>
</tr>
<tr>
<td class="projectdivider">Computing time</td>
<td class="projectdivider"><?php $time = secondstodate(number_format($task->active_task->current_cpu_time,0,'','')); echo $time["hours"]<1 ? '0 Hours ' : $time["hours"].' Hours ' ; echo $time["minutes"]<1 ? '0 Minutes ' : $time["minutes"].' Minutes ' ; echo $time["seconds"]<1 ? '0 Seconds' : $time["seconds"].' Seconds' ; ?></td>
</tr>
<?php
}
}
?>The code references foreach($elements->active_task_set as $task), where $elements->active_task_set is an array element containing a sub-array of active tasks. Instead, we need to change this to reference the sub-array elements, as in foreach($elements->active_task_set->active_task as $task). This way, the foreach statement reads through each sub-array, which contains the info for a single task. Once this has been changed, each subsequent reference to $task->active_task needs to be changed to just $task. Change this code to the following and it should work:
<?php
if(is_object($elements->active_task_set)) {
foreach($elements->active_task_set->active_task as $task) {
?>
<tr>
<td>Project URL</td>
<td><a href="<?php echo $task->project_master_url; ?>"><?php echo $task->project_master_url; ?></a></td>
</tr>
<tr>
<td>Result Name</td>
<td><?php echo $task->result_name; ?></td>
</tr>
<tr>
<td>Work done</td>
<td><?php echo bcmul($task->fraction_done,100,2); ?> %</td>
</tr>
<tr class="noh">
<td></td>
<td><div class="fractioncontainer"><div class="fractiondone" style="width:<?php echo bcmul($task->fraction_done,100,0); ?>%;"></div></div></td>
</tr>
<tr>
<td class="projectdivider">Computing time</td>
<td class="projectdivider"><?php $time = secondstodate(number_format($task->current_cpu_time,0,'','')); echo $time["hours"]<1 ? '0 Hours ' : $time["hours"].' Hours ' ; echo $time["minutes"]<1 ? '0 Minutes ' : $time["minutes"].' Minutes ' ; echo $time["seconds"]<1 ? '0 Seconds' : $time["seconds"].' Seconds' ; ?></td>
</tr>
<?php
}
}
?>This bugfix has been posted to the developer's site, but I've heard nothing back yet. I guess the developer probably just has a single processor machine and as such didn't spot this.
In case anyone's interested in how my BOINC number crunching has been going recently, you can have a look at my BOINC Stats page. I also plan to add a page to this site soon which will grab these graphs and other info (such as that from BOINC LCS) and display them in a nice overview of one of my geek projects!
Update:
The author of BOINC LCS, Wilhelm, has now emailed me to confirm that he has received my bugfix and will be incorporating it in his software.
