{{main|Hoard memory allocator}}
Hoard is an allocator whose goal is scalable memory allocation performance. Like OpenBSD's allocator, Hoard uses <code>mmap</code> exclusively, but manages memory in chunks of 64 kilobytes called superblocks. Hoard's heap is logically divided into a single global heap and a number of per-processor heaps. In addition, there is a thread-local cache that can hold a limited number of superblocks. By allocating only from superblocks on the local per-thread or per-processor heap, and moving mostly-empty superblocks to the global heap so they can be reused by other processors, Hoard keeps fragmentation low while achieving near linear scalability with the number of threads.<ref>{{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.
