Big-Iron to Open Up for AMD

vincecate writes "Traditionally the key chips that have allowed companies to scale multiprocessors to large numbers have been proprietary. Some examples are the Cray SeaStar, SGI NUMAlink, HP sx1000, and the IBM X3/Hurricane. This proprietary paradigm is about to change to a more open one. Two companies have developed key chips for building large Opteron multiprocessors, and they will be commercial off-the-shelf parts. PathScale has released InfiniPath which can be used with an Infiniband switch to make a high-bandwidth low-latency interconnect for a supercomputer cluster. The other company is Newisys, which will soon release the Horus chip. This chip will make it possible to build 32 socket (64-core) shared memory Opteron systems."
