Memory Allocation Costs in Large C and C++ Programs

Dynamic storage allocation is an important part of a large class of computer programs written in C and C++. High-performance algorithms for dynamic storage allocation have been, and will continue to be, of considerable interest. This paper presents detailed measurements of the cost of dynamic storage allocation in 11 diverse C and C++ programs using ve very di erent dynamic storage allocation implementations, including a conservative garbage collection algorithm. Four of the allocator implementations measured are publicly-available on the Internet. A number of the programs used in these measurements are also available on the Internet to facilitate further research in dynamic storage allocation. Finally, the data presented in this paper is an abbreviated version of more extensive statistics that are also publically-available on the Internet.

Dynamic storage allocation is an important part of a large class of computer programs written in C and C��. High-performance algorithms for dynamic storage allocation have been, and will continue to be, of considerable interest. This paper presents detailed measurements of the cost of dynamic storage allocation in 11 diverse C and C� � programs using five very different dynamic storage allocation implementations, including a conservative garbage collection algorithm. Four of the allocator implementations measured are publicly available on the Internet. A number of the programs used in these measurements are also available on the Internet to facilitate further research in dynamic storage allocation. Finally, the data presented in this paper is an abbreviated version of more extensive statistics that are also publicly available on the Internet. key words: Garbage collection Dynamic storage allocation Performance evaluation Conservative collection Dynamic memory managemen
