概要 | In this study, we explored a thousand computation-intensive applications in terms of the distribution of kernel classes, each of which is related to expected efficiency and specific tuning patterns. To statistically estimate the distribution of the kernel classes, 100 loops were randomly sampled and then manually classified by experienced performance engineers. The result indicates that 50-70% of the kernels are memory-bound and hence difficult to run efficiently on modern scalar processors. In addition, based on the classification results, we constructed experimental classifiers for identifying loop kernels and for predicting kernel classes, which achieved cross-validated classification accuracy of 81% and 65%, respectively. |
