A system includes a first node including a first processor and a first memory, and a second node including a second processor and a second memory. A worker thread of the first processor calls an allocation API to allocate a portion of the first memory, and calls a first allocator of a first memory manager associated with the first node to allocate a specified size of the first memory. The first memory manager calls an operating system function to reserve a memory segment of the specified size, sets a first Non-Uniform Memory Access policy of the first node to preferred, binds the reserved memory segment to the first node, adds the memory segment to a global freelist, and returns an address pointer of the reserved memory segment to the worker thread.
