WORK STEALING FOR CONCURRENT MARKING GARBAGE COLLECTION WITH FINGER POINTER

Abstract:

A computer-implemented method, system, and computer program product are provided. The approach includes popping a first task from a queue of a garbage collection thread. The approach also includes identifying a second task from the popped first task, where the second task is associated with a bit of a bitmap and the bit is located at a location within the bitmap that has not yet been passed by a finger pointer. The approach also includes pushing the second task to the queue of the garbage collection thread.
