Nettet29. jan. 2014 · For small allocaitons, it still performs similarly to tcmalloc. However, beyond about 64KiB, it drops drastically in performance. It uses a central "hoard" to redistribute memory between threads. This presents a bottle-neck as only one thread at a time can be using it. As the number of threads increases, the problem gets worse and worse.

NettetThe advent of 64-bit highly threaded applications running on tens, if not hundreds, of cores resulted in a clear need for a multithread-aware memory allocator. By design, Oracle Solaris ships with two MT-hot memory allocators, mtmalloc and libumem. There is also a well-known, publicly available MT-hot allocator named Hoard. Hoard Nettet1. apr. 2024 · Hoard, proposed by Berger et al., is a typical scalable memory allocator for multi-threaded applications [7]. Each thread corresponds to a local heap and all thread share a common global heap. Once the mapping relationship between a thread and a local heap is determined, the thread will only access the corresponding local heap. god of weapons china

Hoard is the first allocator to simultaneously solve the above problems. NettetHoard was designed primarily by Professor Emery Berger of the University of Massachusetts Amherst, based on his PhD thesis work at the University of Texas at Austin. The Hoard memory allocator has been in continuous development for over 15 years. Hoard has been licensed by numerous companies to improve their application … booking card for travel
