Abstract

On vector supercomputers, vector register processors share a global highly interleavedmemory. In order to optimize memory throughput, a single-instruction, multiple-data(SIMD) synchronization mode may be used on vector sections. We present an interleavedparallel scheme (IPS). Using IPS ensures an equitable distribution of elements on a highly interleaved memory for a wide range of vector strides. Access to memory may beorganized in such a way that conflicts are avoided on memory and on the interconnectionnetwork.
