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." -
Buses and Interconnects: The Next Generation
mkarpinski writes "ExtremeTech has posted a nice overview of the next generation of peripheral buses and interconnects including PCI-X, InfiniBand, 3GIO, and HyperTransport. From the article, "All these future interconnects and buses have a few things in common. They use packet-based, point-to-point connections; in fact, InfiniBand implements a full switch fabric. They provide bandwidth in multiples of that offered by PCI. They decrease latency significantly, with HyperTransport and RapidIO showing the most dramatic decreases, crucial for their target communications and embedded markets. And all four strive to reduce pin counts in order to conserve power and system real estate." Open the floodgates!"
