there is no explicit numa support in the pc kernel. however it runs just fine on standard x86-64 numa architectures like intel nelaham and amd opteron. we have two 10gbe ethernet drivers the myricom driver and the intel 82598 driver. the blue gene folks have support for a number of blue-gene-specific networks. i don't know too much about myrinet, infiniband or quadratics. i have nothing against any of them, but 10gbe has been a much better fit for the things i've wanted to do. - erik
