This paper gives an overview of the BlueGene/L Supercomputer. This is a jointly funded research partnership between IBM and the Lawrence Livermore National Laboratory as part of the United States Department of Energy ASCI Advanced Architecture Research Program. Application performance and scaling studies have recently been initiated with partners at a(More)
As 1999 ended, IBM announced its intention to construct a one-petaflop supercomputer. The construction of this system was based on a cellular architecture—the use of relatively small but powerful building blocks used together in sufficient quantities to construct large systems. The first step on the road to a petaflop machine (one quadrillion floating-point(More)
Large powerful networks coupled to state-of-the-art processors have traditionally dominated supercomputing. As technology advances, this approach is likely to be challenged by a more cost-effective System-On-A-Chip approach, with higher levels of system integration. The scalability of applications to architectures with tens to hundreds of thousands of(More)
