I'd highly recommend you use a later kernel since there has been a lot of NUMA work since 2.4 days. Checkout libnuma and the mempolicy system calls, as this can help you control how your program uses your NUMA machine (e.g. set up mappings to use interleaved memory, etc). You probably also want to check out hugetlb for your large mapping. Unfortunately you will need to code a lot of this support directly (at least until we get transparent superpages, but that's for another day... :) -i
