I was wondering is there anyway that a user process can see its list of (memory) pages that has been modified (since the last checkpoint of the process). This is with respect to checkpoint-restart Fault tolerance. I want a process to write all modified pages to a persistant file periodically (say local disk) just-in-case the process crashed due to system failure. Please cc me in your reply (mkkcbe@gmail.com). -- Thanks, -Kay.
