Abstract: An example system comprises a memory, one or more processors coupled with the memory and configured to execute a plurality of threads, and a memory controller. The memory controller receives a request to allocate memory space for a first thread of the plurality of threads. The memory controller selects a first memory page from a plurality of memory pages in the memory. The memory controller determines whether the first memory page is currently allocated. The memory controller allocates the first memory page for the first thread based on a determination that the first memory page is not currently allocated. The memory controller selects a different memory page from the plurality of memory pages for the request based on a determination that the first memory page is currently allocated.
