Abstract
A thread on a processor core executes one or more instructions to write file data for a file into a persistent memory save area. The instructions to write the file data have the effect of storing the file data for the file in the cache associated with the processor core. The thread running on the processor core flushes the file data from the cache to the persistent memory save area while retaining the file data in the cache. The thread running on the processor core copies the file data from the cache for the processor core into a persistent copy of the file that is stored in persistent memory.
