Embodiment Construction

[0021] The invention is described below with reference to methods and devices according to embodiments of the invention. Wherein, each block in the flowchart and / or block diagram and the combination of blocks in the flowchart and / or block diagram can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine such that execution of these instructions by the computer or other programmable data processing apparatus produces implementing flow diagrams and and / or means of function / operation specified in a block in a block diagram.

[0022] These computer program instructions can also be stored in a computer-readable medium that can instruct a computer or other programmable data processing device to work in a specific manner, so that the instructions stored in the computer-readable medium generate a pro...

Abstract

The invention provides a handling method and a system for new memory access events; the method comprises the following steps: an expanded procedure is carried out, and the expanded procedure comprises an inserted memory tracking code to track memory access events of a plurality of objects conveniently; unique identifiers are respectively distributed on a plurality of the tracked objects; weak references are respectively built for a plurality of the tracked objects, and mapping relation is built between the identifier for weak reference and the corresponding identifier of the object which is tracked; the memory access events of a plurality of the objects care recorded, stored and tracked; a notice for memory rubbish recovery, which is received, is responded, the notice comprises a weak reference identifier for a recycled object, the identifier of the recycled object is determined according to the mapping relation between the weak reference identifier and the corresponding identifier ofthe tracked object, and the memory access events of the recycled object are searched in the stored memory access events; and the memory access events of the recycled object are deleted; by adopting the method, the memory overhead can be reduced.

Description

technical field [0001] The invention relates to data processing in a computing system, in particular to a processing method and system for memory access events. Background technique [0002] In the past two decades, with the rapid development of microelectronics technology, the performance and capacity of computer systems have grown explosively. More computing resources mean that more complex software can be developed to handle complex problems. In addition, more computing resources also mean that more operations can be performed simultaneously in a parallel manner. Consequently, parallel architectures, as well as parallel software development, play an increasingly central role in information processing. However, parallel software for dealing with complex problems (eg, software involving multiple threads) also becomes more complex itself. [0003] A process is a program or part of a program running on a computer system, or a related sequence of steps performed by a progra...
