'''Parallel Self-organizing Modeling'''. F. Lemke '''Abstract.''' ''This paper reports real-world performance tests of a computationally intensive, cross-platform mathematical self-organizing modeling algorithm we have been developing. It implements vector processing (SIMD) and shared-memory multi-threaded processing (MIMD) for multi-core processors or multi-processor CPUs. We tested scalability and speedup of eight different implementations of the algorithm on datasets with growing number of samples on both 32-bit and 64-bit Mac OS X systems running on eight-core Intel Xeon based hardware.''
