I got a 32 bit executable even if I'm running a 64 bit OS (W7u x64). It seems working, anyway...

Server group said that sometimes BOINC give 32 bit application also in 64 bit machines. After some time it gives the 64 bits version. I have the 64 bits version and in my case Boinc is running correctly.

I added the following line into config.xml

1
Send hosts app versions for their primary platform if one exists; e.g. if a host is 64-bit, don't send it a 32-bit CPU version if a 64-bit CPU version exists. Use this option only if you're sure that your 64-bit versions are faster than the 32-bit versions.

We need to check if the above statement is true, if not we may also discard the x64 version at all.

Run times of my test on a tile of 20 rows:
I run the same case three times, time is measured with unix command "time":

32 bit: 3.55min 3.55min 3.54min
64 bit: 3.12min 3.12min 3.12min

Diff on output files does not return any row, so result is the same.
64 bit version shows a nice gain in performance :)
