Performance of a serial code often relies on compilers' capabilities for automatic parallelization. In such a case, the performance is not portable to a new system because a new compiler on the new system may be unable to effectively parallelize the ode originally developed assuming a particular target compiler. As the compiler messages from the target compiler are still useful to identify key kernels that should be optimized even for the different system, this paper proposes a method to migrate a serial code to the OpenMP programming model by using such compiler messages. The aim of the proposed method is to improve the performance portability across different systems and compilers. Experimental results indicate that the migrated OpenMP code can achieve a comparable or even better performance than the original code with automatic parallelization. © 2014 Springer International Publishing.
