Abstract
A method for zeroing memory in computing systems where access to memory is non-uniform includes receiving, via a system call, a request to delete a memory region. The method also includes sorting, after receiving the request, one or more pages of the memory region according to each associated affinity domain of each page. The method 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 method further yet includes waiting, after sending the requests, to return to the system caller until a message is received, from the zeroing threads in each affinity domain, indicating that all the page zeroing requests have been processed.
