Hoard memory allocator

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 https://elyondigital.com

NettetKeywords: Memory allocator · Lock-freedom · Implementation 1 Introduction Dynamic memory allocation is an important component of most applications. Nowadays, due to the use of thread-level parallelism by applications, an impor-tant requirement in a memory allocator implementation is the ability to be thread safe. Nettet23. mai 2024 · Dynamic allocation of memory uses the heap of the application/module/process (but not thread). The heap can only handle one allocation request at a time. If you try to allocate memory in "parallel" threads, they will be handled in due order by the heap.
