Demo of aggregating results of all executions of slambench across all platforms (different CPU, GPU, frequency, compiler, etc). It can help build a realistic training set for further machine learning based autotuning and run-time adaptation as described in our papers [1, 2, 3]. We can use it to find an optimal platform for a given data set (balancing execution time, energy/frequency, accuracy, price, cost, etc - particularly useful for cloud computing or mobile devices).
