The BlueGene/L supercomputer will consist of 65,536 dual-processor compute nodes interconnected by two high-speed networks: a three-dimensional torus network and a tree topology network. Each compute node can only address its own local memory, making message passing the natural programming model for BlueGene/L. In this paper we present our implementation of… (More)

The IBM BlueGene/L (BG/L) super-computer holds 3 of the top 10 rankings on the 26th TOP500 list of LINPACK performance. The system is novel in its design in many aspects when compared to other more traditional high-performance computing systems. When developing system libraries as well as when tuning application code for BG/L it is essential to be able to… (More)
