View Full Version : [ubuntu] 64 bit vs 32 bit?

August 25th, 2011, 06:22 PM
Hi! So I just got a new computer, and it's a 64 bit. I've been using 32 bit Ubuntu on my other computers, should I install 32 bit on the 64 bit? On the Ubuntu Website it said recommended next to the 32 bit, but not next to the 64 bit, why is that?

This should be helpful for you to decide:

About why 32 bit is recommended, I think that is because there are still some applications and libraries that are actually made only for 32 bit processors (but you can install ia32-libs to make them work on your 64 bit OS). I also just got some x86_64 nodes for my project and it is a bit problematic. However, there is a limit to the RAM that you can use with 32 bit OS which is 4GB (=2^32 bytes so 2^32 addresses possible using 32 bits only).

It recommends 32bit since that will work on 64bit computers as well as 32bit computers. Without getting into a big long discussion - if you have a 64bit capable machine, definitely install a 64bit OS to get full utilization from your machine.
