I am building a new system which will have a pair of dual-core Opterons and 16GB memory. Should I use kernel-smp or kernel-hugemem? I see that RH recommends the hugemem kernel if you have more than 16GB (and we may upgrade at some point, the MB supports 32GB). Any comments on this? The only difference that the descriptions show is the 4GB/4GB split with the hugemem kernel and I'm not quite clear on what that does. -- Bowie

I guess there's not a hugemem version for 64-bit, so I'll just go with kernel-smp. I forgot about that minor detail. Most of my machines are only 32-bit. -- Bowie
