Exploiting memory affinity in OpenMP through schedule reuse
Rights accessRestricted access - publisher's policy
In this paper we explore the possibility of reusing schedules to improve the scalability of numerical codes in shared--memory architectures with non--uniform memory access. The main objective is to implicitly construct affinity links between threads and data accesses and reuse them as much as possible along the execution of the application. These links are created thorugh the definition and reuse of iteration schedules statically defined by the user or dinamically created at run time. The paper does not include a formal proposal of OpenMP extensions but includes some experiments showing the usefulness of constructing affinity links in some irregular codes.
