Abstract
A method for zeroing memory in computing systems where access to memory is non-uniform includes receiving, via a system call, a request for a pool of memory, 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 dummy memory segment is filled with one or more pages, based on the determined size of the requested pool of memory, and the dummy memory segment is deleted.
