MAI: Memory Affinity Interface
Résumé
In this document, we describe an interface called MAI. This interface allows developers to manage memory affinity in NUMA architectures. The affinity unit in MAI is a variable or an object of the parallel application. A set of memory policies implemented in MAI can be applied to these variables/objects in a easy way. High-level functions implemented in MAI minimize developers work when managing memory affinity in NUMA machines. MAI's performance was evaluated on two different NUMA machines using three different parallel applications. Results obtained with \mai present important gains when compared with the standard memory affinity solutions.
