SMP is one of the kernels during bootup.  If it isn't installed, install it from the original dvd.

even though kernel-hugemem is installed it does not seem to be enabled as the system is not able to recognise more than 8 cups although the system has 16 cpus
Is there a configuration file that needs to be edited to have this feature enabled?

I can only assume that you have quad core cpu's and you have 4 in the server.  Redhat ES 4 only supports 2 physical CPU's, hence how you can only see 8 CPU's (2 Cpu's x Quad core = 8 Cpu's) if you want to utilise all cores you will need to use Redhat AS 4.
