Abstract

In recent years, we begin to see Java-based systems embrace off-heap allocation for their big data demands. As of today, these system rely on simple ad-hoc garbage-collection solutions, which restrict the usage of off-heap data. This paper introduces the abstraction of safe off-heap memory allocation and reclamation (SOMAR), a thread-safe memory allocation and reclamation scheme for off-heap data in otherwise managed environments. SOMAR allows multi-threaded Java programs to use off-heap memory seamlessly. To realize this abstraction, we present Nova, Novel Off-heap Versioned Allocator, a lock-free SOMAR implementation. Our experiments show that Nova can be used to store off-heap data in Java data structures with better performance than ones managed by Java’s automatic GC. We further integrate Nova into the open-source Oak concurrent map library, which allows Oak to reclaim keys while the data structure is being accessed.
