Multi-chipset systems, to hook multiplex GPUs (to accelerate computation) and NICs (tightly coupled processors/gpus crosswise computing lymph glands). But hold attention, among other things, to [nc/c]HT topologies to avoid runway out of bandwidth (ie. resource limitations) surrounded by devices when the HPC practise starts pushing to the limits in all directions. 12/7/2011 pre-Exascale HPC systems Saudi Arabian HPC Symposium, Al-Khobar  typesetters baptistry: break up NFS (RNANETWORKS) all over 4 QDR IB cards FAT node in 4U 8xSix-core @ 2.
