Along with the automatic test and installer package, I've updated the downloads to Release 1.3 of the science applications.
This update is a cosmetic fix - it inserts information about the true CPU speed into the stderr section of each result.
An example - my Pentium D says it's a 2.66 GHz CPU and BOINC records this information. It actually runs at 3.85 GHz, though (it's overclocked).
Monza_MH26 (http://lunatics.at/index.php?action=viewprofile;user=Monza_MH26) suggested it's a good idea to show the real CPU speed as well - I agree and added it.

Just a suggestion : modify your naming conventions to incorporate the release version, something like that to keep the filenames not too long ?
setiathome-5.15-kwsn-mmx.exe -> S@H-5.15-kwsn-1.3-mmx.exe

Been thinking about that, too - sounds good. Have t think about it a little more :)

Noting actual clock is very good, particularly for system comparison. If the measurement routine is light enough, it might also be used to get an average clock by measuring periodically (perhaps when checkpoints are written). Summing those measurements and keeping a count would allow showing the average clock raste.
For those crunching on laptops which are on battery sometimes or even desktops with marginal cooling causing CPU slowdowns, that average rate might be more meaningful.

It's using an IPP function -
#ifdef USE_IPP
int myfreq;
ippGetCpuFreqMhz(&myfreq);
fprintf(stderr,"CPU real speed: %d MHz\n\n",myfreq);
#endif
This is what I inserted into the code. No idea how heavy the overhead for that function is, but I believe it's very small.

Is there any chance you could put a date or version number on the downloads so credit hounds like me can see if anything is new?

Good idea, will do that on the next update.
Also, I will make a page that lists the most recent versions, release dates etc. so you always know what's what.
