Our machine is 64 bit and compiler is 64 bit. The compiler code should be 64 bit automatically or there is some specifications? I am talking about version 9.1 here.

with a 64bit compiler in a 64 enviroment it should be 64 bit (assuming by "64 bit machine" a 64 bit Operating System)

The Intel compilers don't have a switch to change between 32- and 64-bit. If you are using the "Intel64" or "em64t" compiler (the one normally installed under /opt/intel/fce/ for 9.1) you get 64-bit code. ifort -V will tell you which compiler is active.
