The case for a read barrier . With a read barrier, objects are traced by two di erent mechanisms during a garbage collection. The case for a read barrier . With a readbarrier, objects are traced by two di erent mechanisms during a garbage collection. Each pointer represents a unique local direction that must be embedded into a one dimensional virtual memory system.
Pointers also point to program functions stored in virtual memory.
We conclude in Section 7. Comparatively little attention has been paid for implementing automatic storage reclamation for large persistent object storage systems, and none that we are aware of considers the client server model. With a readbarrier, objects are traced by two different mechanisms during a garbage collection. The cost of these checks is high on conventional hardware, because they occur very frequently. This collector avoids performing exhaustive background scavenging until toward the end of the garbage collection cycle, to enhance the odds that objects will be reached first by the mutator, and copied in a locality enhancing order.
