==History==

In 2000, its author [[Emery Berger]] benchmarked some famous memory allocators and stated Hoard improves the performance of multithreaded applications by providing fast, [[scalable]] [[memory management]] functions ([[malloc]] and [[Free (programming)|free]]). In particular, it reduces contention for the heap (the central data structure used in [[dynamic memory allocation]]) caused when multiple threads allocate or free memory, and avoids the [[false sharing]] that can be introduced by memory allocators. At the same time, Hoard has strict bounds on [[fragmentation (computer)|fragmentation]].<ref name=Berger2000>{{Cite conference | doi = 10.1145/378993.379232| title = Hoard: A Scalable Memory Allocator for Multithreaded Applications| work = Proceedings of the ninth international conference on Architectural support for programming languages and operating systems| conference = [[International Conference on Architectural Support for Programming Languages and Operating Systems|ASPLOS]]-IX| pages = 117–128| date=November 2000 | last1 = Berger | first1 = E.

It has also inspired changes to other memory allocators such as the one in [[OS X]] since February 2008 (first released in [[Mac OS X Snow Leopard]]).<ref>{{cite web |title=I’m a Mac (or, “Emery Inside”) |url=http://emeryblogger.com/2010/10/26/im-a-mac-or-emery-inside/}}</ref><ref>{{cite web |title=A look at how malloc works on the Mac |url=http://www.cocoawithlove.com/2010/05/look-at-how-malloc-works-on-mac.html}}</ref>
