Subject: [Boost-users] MPI rank() & size() type

Hello,
I use Boost MPI for some project, but I have a question of the return
datatype of the communication rank() and size(). size() returns a
unsigned datatype, but rank() a signed, so if I compare rank() with
size() I will get a warning. Is there a reason for using different
return types?
Thanks
Phil
