Automatically Optimized FFT Codes for the BlueGene/L Supercomputer


IBM’s upcoming 360 Tflop/s supercomputer BlueGene/L featuring 65,536 processors is supposed to lead the Top 500 list when being installed in 2005. This paper presents one of the first numerical codes actually run on a small prototype of this machine. Formal vectorization techniques, the Vienna MAP vectorizer (both developed for generic short vector SIMD… (More)
