More Information
Summary:Embodiments disclosed herein generally relate to techniques for zeroing memory in computing systems where access to memory is non-uniform. One embodiment provides a processor which performs an operation including receiving, via a system call, a request to delete a memory region. The operation also includes sorting, after receiving the request, one or more pages of the memory region according to each of the one or more pages associated affinity domain. The operation further includes sending requests to zero the sorted one or more pages to one or more zeroing threads that are attached to the respective affinity domain. The operation further yet includes waiting, after sending the requests, to return to the system caller until a message is received, from the worker threads in each affinity domain, indicating that all the page zeroing requests have been processed.
