fahinfo.org is a database of collected Folding@Home project scores. The scores are submitted along with details about the CPU on which they were run. This information will show which workunits are best (and worst) for specific CPUs, and also highlight the differences between the different cores on the same CPU type. The more data collected and added the better, as this will serve to make the PPD/GHz values more accurate. You can lookup the work-unit (by project number) you are currently running to see how well it could or should be doing on your particular CPU, I might even make it recommend the CPU that you should be using for that WU. This site was written by and is maintained by me, Uncle_Fungus, and has been hand-coded from scratch in PHP and MySQL.

The CPU comparison graph generator in the Buyers Guide section can now be configured to include data from the benchmark machine in a "3-way" comparison. In addition to this update the query to detect which cores should have mini-graphs has been updated and shouldn't produce links when there isn't data for them.
Thanks to 7im (folding-community forum Moderator) for this suggestion
You may also notice a short delay before the graph page updates after requesting a CPU comparison. This is because the new queries to filter results and generate the charts are very CPU intensive and so the time in which they are generated has increased slightly.

The second part of the advanced filtering system has been implemented. You can now filter the data that appears on the user-specific parts of the "All Scores" section. You can filter the data by Machine Name in addition to the standard options from the previous update thanks to some impressive mysql queries.
It is still possible to submit stupid queries like choosing a Machine name in addition to a Manufacturer different to that registered machine. Luckily all this will do is produce a blank table.
The tables accessible from "Your Account" still don't have these features, but much of the code used for this update can be applied to those tables so it won't take long (I hope).

After a flurry of activity this afternoon, I've added some extra features to the publicly accessible data tables.
Having fixed my AJAX code to allow multiple simultaneous requests, I've added some filtereing capabilities to the "Score Lists" and "Average Scores" pages. These allow broad filtering of the results based on dropdown selections. For instance you can now apply a filter that will only show results submitted by processors with a Northwood Core, or select results by a particular user.
With this in mind, the active user list has been updated to link back to the Scores List page, and show all results submitted by that particular user. If for example, you wanted to see all scores submitted by me, you would be directed to this location: http://fahinfo.org/index.php?allscores=true&new=false&searchid=All,All,All,All,All,Uncle_Fungus
Improvements have been made to the "Averages Scores" page too in addition to the filters, hovering over a set of values will show a popup graph of the data used to create the averages, in the same way as happens on the WU Search results tables.
A functional modification has been made to the CPU Comparison Chart Creator too, thanks to the AJAX fixes, you can now select the two CPUs independently of each other, there is no longer a need to fill in all the details for one CPU before you can access the second.
At the moment the filters don't apply to the user-specific tables, since that will require a little more work because of the more complex database interactions used to show registered machine names. Also, it is possible to submit completely stupid queries, like an AMD Pentium 4, since the filters are interdependent and simply show all data available to be filtered. Selecting one of these combinations will just result in a blank table.

Please do not submit scores for SMP WUs if you've run them using VMware (either Linux on Windows, or Linux on Linux) as they will interefere with the average scores generated and basically make all SMP WU comparisons completely invalid.
VMware machine's clocks often go out of sync with the host machine introducing frame time errors, AND there is a performance hit when running the SMP client inside a VM, which can vary between 15-20% over running the client natively.
At some point in the future a facility for submitting VMware scores may be introduced, but for now can people please NOT, for the sake of data integrity.

I've just fixed a non fatal bug in my project update script that prevented it from purging old projects from the "current" list. The normal list of projects available on the "Submit score" page is now much smaller as these extra entries have been removed. The complete list is still available and that hasn't been affected by the fix.
I'm currently (read "whilst not revising for exams") writing a filtering system for the raw data pages. When this is finished it should be much easier to find an raw data that you want. The filter systems will also be extended to data tables available within you own account too.
