umem (devel/umem) Add to my watchlist 0

Libumem is a library used to detect memory management bugs in applications. It is based on the Slab allocator concept. Functions in this library provide fast, scalable object-caching memory allocation with multithreaded application support. In addition to the standard malloc(3C) family of functions and the more flexible umem_alloc(3MALLOC) family, libumem provides powerful object-caching services as described in umem_cache_create(3MALLOC). This slab allocator is designed for systems with many threads and many CPUs. Memory allocation with naive allocators can be a serious bottleneck. There are other highly scalable allocators out there, but libumem is about the same or better in terms of performance, and has compelling debugging features.
