Prob- lems appear when objects are unused but cannot be garbage-collected because they are still referenced from other objects. This is an issue because those ob- jects waste primary memory and applications use more primary memory than they actually need. We claim that relying on the operating system's (OS) virtual memory is not always enough since it cannot take into account the domain and structure of applications. At the same time, applications have no easy way to parametrize nor cooperate with memory management. In this paper, we present Marea, an efficient application-level object graph swapper for object-oriented programming languages. Its main goal is to offer the programmer a novel so- lution to handle application-level memory. Developers can instruct our system to release primary memory by swapping out unused yet referenced objects to secondary memory. Our approach has been qualitatively and quantitatively val- idated. Our experiments and benchmarks on real-world applications show that Marea can reduce the memory footprint between 23% and 36%.Lire moins >
