Ubuntu 14.04 64-bit
Boinc Manager 7.2.42 (x64)

I installed the Boinc manager from the Ubuntu repository, but let it download the project software as it saw fit.

Looking in /var/lib/boinc-client/projects/setiathome.berkeley.edu, I see

setiathome_7.01_i686-pc-linux-gnu
and
setiathome_7.01_x86_64-pc-linux-gnu

as well as

astropulse_6.01_i686-pc-linux-gnu
and
astropulse_6.03_x86_64-pc-linux-gnu

I know that both setiathome executables have been used; don't know about astropulse.

Why are they both there, and what determines which one is used for a task?
