You mean a SGI altix3000 node. That's a box from $500k with 16 bricks (4 processors a brick and each brick has 2 mainboards with interconnects) so in total say 64 hydra cards. each card say $3000. >Feasible? Donninger has more interesting things to do than to get 64 hydra cards to work. >If so, what performance could be expected? Quite a bit worse than in paderborn, i am very sure that they will have major problems to get to work 64 cards at a cluster. I doubt they ever will manage to get to work more than 16 nodes (currently that would be 32 cards with 2 cards a node). >Note that it might not be necessary to combine the Hydras in the most efficient >way possible. Maybe not SMA. It works at cluster currently with slow MPI calls transferring a lot of data using broadcasts. In short, they will not scale easily to more than 4 dual xeon nodes. >Bob D.
