PERSISTENT MEMORY FILE SYSTEM WITHIN RECOVERABLE APPLICATION MEMORY WITHIN VOLATILE MEMORY

摘要

Aspects of the invention include a persistent memory file system within recoverable application memory within volatile memory. A non-limiting example computer-implemented method includes designating, by a processor, a portion of the system memory as recoverable application memory and establishing, by the processor, a portion of the recoverable application memory as a heap-backed memory file system. The computer-implemented method remounts, by the processor, the heap-backed memory file system following an initial program load. This heap-backed memory file system is available for general application use and for use as an internal caching mechanism for other cluster consistent file systems.
