AFFINITY-AWARE PARALLEL ZEROING OF MEMORY FOR INITIALIZATION OF LARGE PAGES IN NON-UNIFORM MEMORY ACCESS (NUMA) SERVERS

摘要

Embodiments disclosed herein generally relate to techniques for zeroing memory in computing systems where access to memory is non-uniform. One embodiment provides a method. The method generally includes receiving, via a system call, a request for a pool of memory. The method also includes determining a size of the requested pool of memory, and creating a dummy memory segment. The size of the dummy memory segment is larger than the size of the requested pool of memory. The method further includes filling the dummy memory segment with one or more pages, based on the determined size of the requested pool of memory, and deleting the dummy memory segment.
