Resum
This paper compares data distribution methodologies for scaling the performance of OpenMP on NUMA architectures. We investigate the performance of automatic page placement algorithms implemented in the operating system, runtime algorithms based on dynamic page migration, runtime algorithms based on loop scheduling transformations and manual data distribution. These techniques present the programmer with trade-offs between performance and programming effort. Automatic page placement algorithms ar...
