Sourcefinder is about testing the performance and quality of the Duchamp Sourcefinding application.
We've built a simulated cube of the sky containing various radio sources, and it's the job of Duchamp to work out where the sources are. We plan on running Duchamp over the whole cube of simulated data to work how many of the radio sources in the cube it can find. Duchamp will need to be able to identify correct sources while keeping false positives to a minimum.
As this project is in beta, we welcome any sort of feedback, advice, or bug reports. You can either make a post on the forums or send us an email at email@example.com . We're happy to hear from you.
Update 26 April 2017
Added a field to the main user page that shows your total CPU time and average CPU time per result across all hosts.
Pushed out another set of work units for this week. I'm currently in the process of packaging up some additional work units, as we ran out fairly fast last week. The extra work units are currently transferring over to the main server, so I'll push them out later this week (probably tomorrow).
The stats for this first week are:
Total Cubes: 10416 Total Results: 19199 Total Canonical Results: 6737. 64.6793394777% Average Results Per Cube: 1.84322196621 Good Results: 17607. 91.7079014532% Bad Results: 1592. 8.2920985468% Client Bad: 1562. 8.13584040835% Client InProgress: 30. 0.156258138445% Client Good: 17607. 91.7079014532% Server Inactive: 0. 0.0% Server Unsent: 3491. 18.1832387103% Server InProgress: 371. 1.9323923121% Server Over: 15337. 79.8843689776%91% good results so far, which is fairly decent. It seems likely to me that the additional percentage of bad results are likely due to the increase in the number of work units that are sent out to each host. We've had a few people posting on the forums about getting too many work units. Hopefully the percentage of bad work units will settle down over the course of the next few weeks as people adjust their project preferences. If anyone else has had an issue with too many work units on any of their hosts, please see this thread.
We're now ready for Production!
Yup, the day has come. Sourcefinder is finally moving from testing to production!
Most of the bugs and issues we've been having during testing have been ironed out to a level that I'm happy with.
All testing work units have been cancelled, and all work units and results have been archived.
We're now going to begin to crunch actual data, 681GB of it!

Update 12 April 2017
I haven't heard much back from anyone concerning our Virtual Box problems, so I've decided that we'll just have to put up with the odd hitch along the way.
Most of the errors were fairly uncommon, so hopefully we'll be able to deal with them as they come.
As of next week (19th April) I plan on moving Sourcefinder from beta to proper production. We'll still use this same server, so there'll be no need to re-attach or swap to another project.
Next week be erasing all of the work units we've run so far, and cleaning up the database in preparation for the production runs. I'm going not going to modify anyone's credit though, you all deserve to keep that for the work you've done so far :)
I'm going to let the current set of work units run for the rest of this week and compare the results to those from a local run I've been doing. I'm expecting identical or very close to identical results.
So thank you everyone for your efforts so far, and I look forward to finally getting this project complete :)

Changelog 5 April 2017
Fixed a small bug with the assimilator.
It turns out that the project has been disabled the whole week, so the db dump hasn't been running and neither has the assimilator. I'm just waiting for everything to get up to speed again, then I'll push out some new work units and provide this week's stats.
I've been posting some of our virtualbox issues to the Boinc forums as well as the boinc_dev mailing list. I'm still waiting on responses.

Changelog 29 March 2017
As per the recommendations made in this thread, I've made a few changes to hopefully prevent the file deleter from erasing the parameters files.
Our weekly stats are as follows:
