We then use Principal Components Analysis, and hierarchical and K-means clustering algorithms to determine the similarity of the benchmarks based on their energy-delay production bottlenecks. Therefore, an assortment of performance tuning utilities and strategies are necessary to best utilize scarce resources (e.g., bandwidth, functional units, cache). The lattice-Boltzmann method is well suited for implementation in single-instruction multiple-data (SIMD) environments provided by general purpose graphics processing units (GPGPUs). This paper proposes a fast, novel approach for the HW/SW codesign of computer systems based on a computational capacity model. This framework is more informative than simple benchmarking, or microbenchmarking. Also, the changes in IPC due to design changes are found to be proportional to the changes in IPC in the original applications. Thus, an objective comparison has become a harder task. Therefore, a programmer extracts pieces of code from large programs, as candidates for the performance tuning. Leiserson et al.
