Abstract

We present a code optimization technique by adapting an auto-tuning (AT) function to an explicit method with the static code generator FIBER. The AT function is evaluated with current multicore processors to match situations with high-thread parallelism (HTP). The results of performance evaluations indicate that the AT function is crucial for HTP, as the speedups of the explicit method with a static code generator are as much as 7.4× compared to that of original implementations based on compiler optimization only.
