Abstract:
An application and system fast launch may provide a virtual memory address area (VMA) container to manage the restore of a context of a process, i.e., process context, saved in response to a checkpoint to enhance performance and to provide a resource efficient fast launch. More particularly, the fast launch may provide a way to manage, limit and/or delay the restore of a process context saved in response to a checkpoint, by generating a VMA container comprising VMA container pages, to restore physical memory pages following the checkpoint based on the most frequently used or predicted to be used. The application and system fast launch with the VMA container may avoid unnecessary input/output (I/O) bandwidth consumption, page faults and/or memory copy operations that may otherwise result from restoring the entire context of a VMA container without regard to frequency of use.
