MCMalloc: A Scalable Memory Allocator for Multithreaded Applications on a Many-Core Shared-Memory Machine

MCMalloc library enables to control local heaps to speed up memory allocation and deallocation by batch malloc, pseudo free, and fine-grained data-locking. (This library is updated version of FCMalloc.)

how to build

Ninja, GCC are required to build MCMalloc library.

$ ninja

how to run

In order to use MCMalloc library, set environment variable LD_PRELOAD to the path to libmcmalloc.so. For example, zsh uses MCMalloc library; e.g.

LD_PRELOAD=./libmcmalloc.so zsh

NOTE

• The following functions are unsupported.
  • pvalloc
  • mallopt
• Memory allocated within libmcmalloc.so is not released unless the process is terminated.
