Multiple processor support for LTSP servers aka SMP
From K12LTSP Wiki
By default the K12LTSP distribution doesn't support multiple processors on the server or the thin clients. There is no reason you need dual processors (aka dual proc) on your thin clients so that won't be covered here. Dual proc support is officially referred to as Symmetric Multi Processor (SMP). To enable SMP support on the servers log into the server as root and run.
yum install kernel-smp
or
apt-get install kernel-smp
You will need to change your boot loader to load the SMP kernel after it is installed.
As soon as I get more detailed instructions I will post them here. The original inspiration for this wiki page came from Dan Young on the k12ltsp mailing list.
Note: For Fedora 6 and later, no separate kernel is needed for smp functionality, the generic kernel will detect and enable it.
