Well, Beowulfery should be following off-the-shelf components. Remember that Infiniband started life as a general interconnect, for attaching devices outwith the chassis, in a converged network style. It only found its niche in HPC as a 'by-product' when HPC types hunting for the most blazingly fast interconnects latched onto it (pun intended). Remember that Intel dropped Infiniband and there was a bit of a stooshie in the HPC world at the time. Thank goodness other manufacturers kept running with it. As other people have said, even if this bus does not have a central switch if you could (say) rack four boxes together and connect them in a mesh, and run RDMA over it you could achieve an single process space machine for not much money. stooshie - a fuss, a fracas The contents of this email are confidential and for the exclusive use of the intended recipient.
