I have a linux machine with Redhat 32 bit SMP Kernel installed , the ram size of machine is 16 GB and processor architecture is 64 bit. Please clarify my doubts on this setup :
- Can OS use the 16GB memory completely ? ( i heard that in windows os if we are using 32 bit , maximum ram capacity is less than 4 GB )
- What is the specialities of SMP kernel compared to the normal one
The following are the redhat-installation details
[user@applicaton ~]$ uname -a Linux applicaton 2.6.18-164.el5PAE #1 SMP Tue Aug 18 15:59:11 EDT 2009 i686 i686 i386 GNU/Linux [user@applicaton ~]$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.4 (Tikanga) [user@applicaton ~]$ lsb_release LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch [user@applicaton ~]$
Can we use SMP along with PAE in linux ?
