Abstract
In response to a memory allocation request received from an application thread, a random number is obtained (e.g., from a random number list previously populated with multiple random numbers). A starting location in at least a portion of a bitmap associated with a region including multiple blocks of the memory is determined based on the random number. A portion of the bitmap is scanned, beginning at the starting location, to identify a location in the bitmap corresponding to an available block of the multiple blocks, and an indication of this available block is returned to the application thread.
