This post attempts to address some of the more common issues that users are having.
If you have anything you think is useful to add to the FAQ, don't hesitate to tell me :)

What is this project about?
We're testing the effectiveness of the Duchamp Sourcefinding application by running it over a large set of simulated data. This is the beta version of the project, where we're focused on solving issues with Boinc and our applications.

Does this project require Virtual Box?
Yes it does. We recommend you download and install the latest version for your operating system from here. Ensure you are using the latest version for your OS! Old versions are not well supported.

I'm not receiving any work units! Help!
Don't worry, I push out work units at least once a week. There'll be more on the way soon.

I only have one work unit per CPU, what's going on?
As this is a beta project, we're not as concerned about the actual data crunching as we are bug removal. We're limiting the number of work units per computer to ensure a reasonable number of people are able to get access to those work units.

My work units increase in progress really fast and then slow down around 99%, what's going on?
Boinc needs some time to work out exactly how long tasks take to be able to estimate the time for each task effectively. Over time, the estimates should get better.

This project has given me too many work units, I can't process them all in time!
You are able to limit the number of work units your local client will process at any one time by creating/modifying the project specific app_config.xml file in ...\Boinc\projects\sourcefinder.theskynet.org_duchamp\. The file should have the following contents:
<app_config>
<app>
<name>duchamp</name>
<fraction_done_exact/>
<max_concurrent>n</max_concurrent>
</app>
</app_config>
Replace 'n' with the number of simultaneous work units you want to run.
More information here.
Thanks to Dave Peachey and LumenDan for their help with this one.

You are able to limit the number of work units your local client will process at any one time by creating/modifying the project specific app_config.xml file in ...\Boinc\projects\54.196.169.236_duchamp\

You can also restrict the number of processors used simultaneously by the Source Finder project with the following app_config.xml file:
<app_config>
<project_max_concurrent>3</project_max_concurrent>
</app_config>

Using the <project_max_concurrent> tag applies the processor limit to all applications from Source Finder so you don't have to update the app_config.xml file when a new application is released.
NOTE: the Source Finder project folder is currently located at ...\Boinc\projects\sourcefinder.theskynet.org_duchamp on a Windows computer.
